Phineas and Ferb: Summer Belongs to You!

Phineas and Ferb plan to travel around the world on the longest day of the year; Linda and Lawrence leave for the weekend leaving Candace in charge. It's the summer solstice, so Phineas, Ferb, & their friends decide to travel around the world in one day in an effort to create the "Biggest, Longest, Funnest summer day of all time". But not everyone believes they can actually achieve what they've set out to do, leading them to get some encouraging words, in the form of a duet, from Clay Aiken and Chaka Khan. Meanwhile, Dr. Doofenshmirtz takes a father-daughter trip to Tokyo with Vanessa.

Act One
Candace calls Jeremy Johnson in Paris to see how his trip is going, even though it's 2:00 a.m. from where he is. He tells Candace that he was dreaming of her, and they were in a Dixieland band with an iguana playing an Oboe. She soon hears some loud noises from the backyard and sees Phineas and Ferb for their latest idea, which is a gigantic jump roping robot. Candace tries to call Linda Flynn, but she can't hear her daughter on account of the construction workers working on the street she's driving on. As usual, when she arrives, the robot is now gone.

Phineas and Ferb look through a scrapbook showing everything they've done so far over the summer, and with summer halfway over, Phineas suggests a real challenge, to make it the "Biggest, longest and funnest summer day of all time." Meanwhile, on a plane up above, Heinz Doofenshmirtz and his daughter, Vanessa, are on a plane to Tokyo. She wanted to go to Paris after dropping some hints, but Tokyo was more exotic, so she didn't mind. While they're flying, the pilot announces that there will be a delay. Doofenshmirtz is annoyed at how flights are constantly delayed and mentions 'turbulence, headwind, a giant-jump-roping robot...' and the jump roping robot that was with Phineas and Ferb is seen dangling from the plane.

Linda and Lawrence Fletcher are leaving for the weekend, leaving Candace in charge. She tells Candace not to have any boys over, but as Jeremy's in Paris for a week, this won't be a problem. They also tell their daughter that being in charge means that she shouldn't be calling them whenever Phineas and Ferb are doing something bust-worthy. She needs to stop them on her own, because she's not doing her job, and she would also be in trouble for not stopping them in the first place. They leave, and Candace and the boys bid them farewell. The next day, at 5:00 in the morning, Candace dreams about Jeremy with French girls, and freaking out, she calls Stacy, who says she will come over. Candace also wants some breakfast, but gets hung up on instead.

In the backyard, Isabella, her troop, and some other kids are outside wanting to know what they're doing up so early. Phineas tells them that they plan to make it the longest summer day ever. Isabella asks why did they build the Statue of Liberty, and Phineas tells her they didn't and removes the sheet. They intend to fly around the world, chasing the sun as they travel westward, making it the longest summer day ever. Buford doesn't believe they can do it, so he makes a bet. If they don't fly around the world "in one day," they have to stand in front of everyone, tell them they are governed by the laws of physics, summer isn't what they make of it, and more importantly, do absolutely nothing for the rest of the summer. If Phineas and Ferb do succeed, he'll eat a bug, but Phineas decides to add giving back the bikes he stole from everyone when they were little. With a duet from Clay Aiken and Chaka Khan, they sing I Believe We Can, and accidentally smash the plane's wing off.

Perry gets a mission briefing from Carl, reading a note that Major Monogram hasn't been kidnapped and not to come looking for him. He tells Agent P that Doofenshmirtz is on vacation with his daughter to go to Japan where the Annual Good Guy Convention is being held and Carl assumes that it's a coincidence and gives him the day off. But Perry is immediately suspicious about this. Candace chats with Stacy about her relationship with Jeremy. Even though they dated, he's never called her his girlfriend and they've never kissed, which means he's single, in Paris, with French girls wanting his attention. Stacy tells her she needs to believe in herself. If she wants Jeremy to be her boyfriend, she has to call him her boyfriend first. Candace thought it was the other way around, so she takes the advice.

While picking up their luggage, Vanessa sees Major Monogram tied up and Dr. Doofenshmirtz introduces her to Major Monogram. She gets annoyed learning her dad had to bring his work with them when they were supposed to just spend some time together.

While the wing gets repaired, Phineas and Ferb have made out a map of their route, with stops in Tokyo and Paris to refuel. Isabella hears Paris, and Phineas invites her to come along. Buford is coming along with them to make sure they don't cheat and brings Baljeet with him. Candace tries to stop them from leaving until Stacy tells her to check out the map. When she sees one of the stops is in Paris, she decides to go with them. Stacy tells her this is a bad idea, since she promised her mom the boys would stay out of trouble. Candace tells Stacy that if she's with them, she can make sure they don't get into any trouble along the way and is aware that it's a massive rationalization. She says goodbye and tells Candace to see her cousins in Tokyo. The jet launches and takes off for Tokyo, leaving the Fireside Girls in charge of cleaning up the backyard and getting the party ready.

Act Two
Vanessa and Doofenshmirtz are at the Tokyo Tower, and Vanessa is reading facts about it, however, it says nothing about a giant water balloon at the top. She immediately blames her father who reveals he plans to drop it on the entire International Good Guy Convention and pin the blame on Major Monogram to destroy his reputation. Therefore, it would put an end to the O.W.C.A.. In another part of Tokyo, Phineas and Ferb make a grindy and sparky landing to meet Stacy's family and her grandmother, Bāchan Hirano. Ferb gets out the plane and tells Stacy's grandmother who they are in Japanese, then she calls out the the other relatives who start to sing J-Pop (Welcome to Tokyo), during which they ask for some vegetable oil to refuel their plane and take off.

Vanessa is still mad at her dad for making their entire trip about his work and leaves for Paris. As she walks away, Perry appears and begins to untie Monogram while Doofenshmirtz tries to convince Vanessa to stay. He is about to push a button to make the balloon fall and to get the whole thing over with, but Perry stops him and causes him to drop the remote. The balloon swings around and knocks Vanessa off the Tokyo Tower. Luckily for her, the Sun-Beater 3000 flies past and she lands on it. She and Ferb recognize each other and the group lets her in. Phineas asks where she wants to go but she decides to stay with them, leaving Doofenshmirtz wondering why they're running off with her. He turns to Perry and Major Monogram, begging them to give him a ride to save her and the two reluctantly decide to help him.

The gang is flying over the Himalayas and Phineas tells them to keep an eye out for Klimpaloon, the magical old-timey bathing suit that lived there. Candace claims he's making it up and notices the altitude meter is beeping. Because Phineas and Ferb didn't calculate the weight of an extra body, the plane loses it's wings and crashes in Nepal, where Klimpaloon walks by. Buford says it looks like they're going to lose their bet, but Baljeet remembers that his Uncle Sabu lived near where they crashed and may be able to help them. Candace and Vanessa decide to stay and guard the plane while the kids head over to see Baljeet's uncle who isn't that far from them. When they arrive at his factory, he sings the song Rubber Bands, Rubber Balls and afterward Phineas asks to borrow one of the rubber band balls.

Act Three
Candace and Vanessa go up the mountain for not getting a cellphone signal, whilst Doofenshmirtz is riding in Perry's hovercraft with Agent P and Major Monogram. Doofensmirtz is using a tracking device, which link up with the earrings Vanessa is wearing. When he spots his daughter on the mountain with Candace, they give him a parachute and an oxygen mask and fling him out of the plane because it was dangerous to land.He fails to pull the cord and lands on the mountain, tumbling toward the two teens in a large snowball. They flee in panic and tell the boys (Who've finished making the giant rubber ball and are putting the plane on top of it) to start the plane. They try, but it keeps stalling and Phineas tells Ferb that he's flooding it, which Ferb denies.

When they finally start it, Vanessa gets flung on board by the snowball but Candace narrowly avoids getting hit by it and it crashes into the plane instead, sending it off the cliff. Then it bounces back up, and she quickly gets on. Finally, the engine starts for real and they take off, blowing the snowball (And Dr. Doofenshmirtz) off of them.Love Handel sings Bouncin' Around the World while they bounce through Singapore, India, China, Italy, Netherlands, Russia, Spain, Egypt, Germany, Monaco, Australia and Belgium. They eventually run out of rubber bands and crash land in a river in Paris, France.

Act Four
The Sun-Beater 3000 is washed up in Paris. Phineas tells everyone they need fuel and parts so they should all split up. Candace goes off to see Jeremy, Buford and Baljeet are to go get some more fuel, and Ferb goes to the Eiffel Tower with Vanessa to plot the directions back home. Phineas decides he will go look for some parts and invites Isabella to come along with him and she quickly agrees. Candace walks around France in search of the hotel Jeremy is staying in.

She comes across a French woman who knows both French and English, but Candace only assumes she only knows French. After failing to understand her, Candace leaves and spots Jeremy around the corner, she tries to say hi, but leaves dejected when she sees him with a bunch of French girls. Meanwhile, Isabella tries to seize a romantic moment with Phineas in Paris, and sings City of Love. While doing so, getting increasingly frustrated when he's too focused on trying to get the plane repaired.

Buford and Baljeet arrive at a cafe to get some vegetable oil for fuel. When Baljeet asks for some, the french man says no. Much to Baljeet's surprise, Buford steps in and reveals that he is fluent in French, he successfully gets the man to give them some oil. Phineas is also successful in finding some parts when he is given some large plastic baguettes that can be used to make their rocket float. On the Eiffel Tower, Vanessa chats with Ferb on about how her father seems to put his work ahead of her when she just wants to have a father-daughter vacation with him. Ferb tells her if you love someone, sometimes, you need to meet them halfway, seeing a flower shop, he leaves to get a flower for her while she thinks of what he said. Heinz suddenly shows up and Vanessa gets upset when she sees him with Monogram and Perry. She is mad at him for bringing work with him again, but he explains that all he did was hitch a ride with them and he had traveled halfway across the world for her. Realizing how much he did care for her, she goes with them. When Ferb returns, she's gone.

Everyone heads back to the plane which has the baguettes connected to it by rubber bands. When Phineas sees Ferb, he asks where Vanessa went, Ferb replies that she went off with someone else. Phineas thinks that's too bad since they were in the city of love so he thought romance would be the conclusion. This immediately angers Isabella (since she never spent a romantic time with him in Paris) so much she breaks her pencil, and Ferb gives her a new one. Then, Candace arrives and Phineas notices she doesn't look too happy. Candace explains that Jeremy had looked happy by himself and that she thought maybe she seemed creepy and obsessive for coming to visit him. Phineas says the same thing as he said to Ferb, making Isabella so angry her head explodes... or at least in her vision. Phineas then tells Candace to believe in herself like Clay Aiken and Chaka Khan said in their song, though Candace missed it, much to everyone's surprise. Candace is finding it hard to believe in anything, so Phineas reminds her of her past accomplishments from being a truck driver, to being the Queen of Mars.

When Jeremy sees her on the bridge, he is surprised she's there so she tells him that her brothers are trying to go around the world in one day, but she accidentally blurts out that she saw him with French girls. He says that "I thought my girlfriend would have more trust in me than that", and upon hearing that, she calls him her boyfriend and tries to kiss him, but the jet is going away and she has to strap in and take off. He tells her he'll see her at the end of the week and they drift off. Candace sits next to Isabella and Isabella says that "At least you got a romantic love scene on a bridge." Isabella seem upset that almost everyone got a romantic love scene except her and Phineas. When they come to a giant frigate, the water balloon that had gone into orbit earlier falls into the ocean and creates a wave that allows them to hop over it. They jet through to the open ocean, realizing they may even make it to Danville ahead of time if nothing goes wrong. As soon as Phineas says that, the Sun-Beater 3000 begins to fall apart, leaving only the seats and them skipping across the ocean.

Act Five
The gang now crash lands on a deserted island and they have one hour left until sundown. Candace comes back after exploring the island and is in hysterics when she returns, telling them that the only things on the island were them, a few trees, and a big ox. Buford laughs at his apparent victory and Candace gets upset that she'll never see Jeremy again. At first, Phineas decides to make a new plane out of materials on the island when he realizes he has nothing to build it with. Refusing to give up, he searches for every possibility in his mind, trying to think of ways to use the seats, one rubber band, and sand.Dr. Doofenshmirtz and Vanessa thank Major Monogram and Perry for the ride and are about to leave, but Doofenshmirtz gets arrested by Perry and he and Major Monogram escort him away. Thinking fast, Vanessa holds the two up and tells them to release her father, and they let her escape with him in Perry's jet. Heinz thanks her, impressed with what she did, however, she tells him she improvised with a hair dryer. Doofenshmirtz says she's still a little evil and is so proud he begins to cry. Monogram decides to return back to HQ and Perry decides to stay in Paris for a bit.

At the deserted island, Phineas is desperately digging a very large hole in search of any useful minerals and only finds a sponge and a starfish. Isabella walks off on her own sadly and sits down to watch the sunset. As she begins to cry, Ferb approaches and offers her a handkerchief. She accepts and thanks him, telling him that she doesn't know what to do. They have been in Paris, yet Phineas hadn't even noticed her, she feels like giving up. Isabella says she would give anything if Phineas could sit with her and enjoy the beautiful sunset, but he was too busy still trying to find a way off the island. Phineas then runs up to her side and suggests digging a tunnel under the ocean. Realizing it wouldn't work, he gives up, sitting next to Isabella to enjoy the sunset. At first, she enjoys it, but after seeing how broken Phineas is that he'll lose his vision, she snaps him out of it and reminds him of the spectacular things he'd did that summer. She tries to tell Phineas that on Ferb's map, giving up was not part of their plan, but Phineas cuts her off and hugs her for reminding him that they still have Ferb's map, leaving Isabella in a trance-like state. Inspired, Phineas has everyone fold it into a giant paper airplane, which they put the seats to their original plane on. They use the last rubber band and place it around the two palm trees and use the ox to pull the rubber band back to make a slingshot. Candace is too reluctant, until Phineas reminds her it's the only way she'll ever see Jeremy again.

The group is shot through the air, flying across the rest of the Atlantic Ocean, past New York, and heading towards the Tri-State Area. Then we see a meeting for 27th Substitute Teachers Day and the giant paper plane flies by and the speaker says "Alright! Who's the wise guy?" When the paper plane crashes lands five blocks away from where they live (Phineas remarks that it is their best landing of the day), they plan to run the rest of the way but stop when they see the construction site it had taken Linda an hour to go around. Buford is disappointed since he had realized what Phineas was trying to tell him and now it seemed hopeless. When he notices they are at his house, he gives everyone their bikes back, except Candace whom he had never stolen from so she is forced to ride a tricycle. At first, she did not listen to Phineas, making him yell at her for the first time because they only had 58 seconds according to Isabella. They quickly pedal down the road and launch off of a ramp and into their backyard where the party is awaiting, making it with no time to spare.

Linda and Lawrence arrive and see that they had a welcome home party, but they're exhausted and decide to let the kids enjoy it. They're especially proud of Candace for being so responsible, as they had no calls from her (which was mostly because Candace didn't have international coverage on her phone). Everyone sings and dances to the song Summer Belongs to You, particularly Phineas, Isabella and Candace. Jeremy arrives from Paris early since he missed his girlfriend and sees the party. He and Candace both embrace and kiss each other. Isabella and Phineas hold hands and dance throughout much of the song. When the song ends, Phineas asks "Where's Perry?" and it is revealed that Perry is still in Paris, ordering at a French restaurant.

Background information

 * This episode is 1-hour long, making it the first hour long episode of the series, officially beating "Phineas and Ferb Christmas Vacation!", which lasted only 45 minutes with commercials.
 * Ferb speaks 9 times in this episode, making this the episode he speaks the most frequently. The majority of his lines were in Act IV (Paris). His largest line was in "The Lizard Whisperer".
 * This explains more of Candace and Jeremy's relationship, Isabella and Phineas's relationship, and Ferb and Vanessa's relationship.
 * First episode that Vanessa interacts with Major Monogram and Phineas.
 * This episode features seven songs, tying Wizard of Odd for the episode with the 3rd most songs. ("The Ballad of Klimpaloon" appears on the soundtrack album, but was not performed in the special itself.)

 * The Summer Solstice, which is known as the longest day of the summer, takes place between June 20 and 21 in the Northern Hemisphere.
 * This special seems to come after all episodes that have aired so far (or at least a good number of them), based on how many references the characters make throughout the episode.
 * "Pair of ducks" is a play on words (paradox) which also describes Candace's situation.
 * Stacy's cousins appear in this special.
 * In the episode, a person who lives in the country speaks English and one of the people in the group speak the native language three times: when Ferb says they are friends of Stacy to Bāchan Hirano, when Candace was asking for directions, and when Buford asks for cooking oil.
 * This is the second episode Phineas actually yells angrily at someone, the target this time being Candace. She refused to get on the little kid trike so they can get home. Phineas reminded her that they were running out of time and when that still didn't work, he angrily yelled, "GET ON THE TRIKE!" and it finally worked. This time, however, is the first time where his yelling is actually sincere and not planned, as the last time he had yelled angrily, it was because it was part of his "Big Idea" for the day. ("Flop Starz")
 * It is proven that Ferb can speak at least some Japanese.
 * It is also proven that Buford can speak French fluently with a French accent. He has also read Voltaire well enough to quote his works.

 * This is the first time in the series where Phineas has actually doubted that his idea could work, when he was on the island and went insane being obsessed in trying to get off the island.
 * Ferb knows about Isabella's crush on Phineas, because when they were stranded on the island, Isabella talked to Ferb about it.
 * The "Hey, where's Perry?" line is said by Chaka Khan after I Believe We Can.
 * Phineas also says this line at the end of the episode, and says "Oh, there you are, Perry" at the beginning, the reverse of the usual pattern.
 * "Poubelle" is the French word for "trash can". Therefore, the hotel Jeremy is staying at is called "Hotel Trash Can".
 * Candace and Stacy are seen eating noodles with chopsticks for breakfast. This may be to a reference Stacy's Japanese heritage.
 * The Idea of lengthening time was once mentioned in "I, Brobot": Phineas said that "We either need more days of summer, or more of us."

 * First episode to never play the theme song or a different version of the theme song.

Goofs in the episode

 * At the beginning of the episode, Phineas comes up with a way to make the longest day of the year, and says, "Ferb, I know what we're gonna do today," but they don't travel the world until the next day.(But it could be possible that the thing they are going to do that day is to build the "Sun-beater 3000".)
 * Phineas says they have 40 hours of daylight. They depart Danville, westbound, early Saturday morning shortly after 5:00 AM. This would place their observed sundown after 9:00 PM the next evening, Sunday. This could include the morning light before they depart. Milly_green_eye.jpg
 * Milly's eyes change color from green to blue to brown to end up staying blue.
 * Buford says he was not a bully until his goldfish Biff was threatened, which does not explain why he stole bikes when he was a toddler ("Voyage to the Bottom of Buford", "The Lemonade Stand"). However, he was a toddler so he probably didn't know better.
 * When Phineas is a toddler, his bike is blue, but later in the episode, his bike is red. However, this could be explained if Buford painted the bike red.
 * They have had their bikes in earlier episodes before. However, this could be explained if they bought new ones.
 * During I Believe We Can after Chaka Khan makes her entrance, Ferb's bigger eye is in the front of his face, while his smaller eye is behind it, where normally, the smaller eye would be in the front.
 * When Clay Aiken and Chaka Khan fixed the Sun Beater 3000, they used all of the packing tape. When Candace sees what the gang are doing, the tape is gone and is not seen again.
 * At the beginning, when Candace and Stacy walk through the back door of the house, Candace rips through Ferb's map, making a gigantic tear; but when they are stranded on the island, Ferb's map has no tear in it at all.
 * Before the wing fell of the plane, Phineas, Ferb, Buford, Baljeet, the Fireside Girls, Clay Aiken, Chaka Khan and the neighborhood kids were on the wing. When the wing fell off the plane, no neighborhood kids were seen on the plane.
 * When Vanessa and Heinz Doofenshmirtz arrived at the airport, when Major Monogram was coming up on the conveyor belt and Doofenshmirtz says, "Oh, here's my bag now," Monogram was tied to a blue pull cart, but as soon as Doofenshmirtz picks him up and the scene zooms out, he was tied to a red cart. Later in the Tokyo Tower, he was tied to a blue cart again.
 * If Major Monogram was 35% metal like he said, he would NEVER had been able to be a "bag" (also the fact that he is a person tied up). Doofenshmirtz even said, "Oh man, it must be hard getting through the airport".
 * While flying over the Pacific Ocean, Baljeet wasn't seen in his seat.
 * In the music video Bouncin Around The World, Candace's socks appear on Isabella and Isabella's socks appear on Candace.
 * In one scene during Bouncin' Around the World, the seats and rubber-bands of the Sun-Beater 3000 aren't colored in.
 * When Doofenshmirtz says, "According to this SPG..." at first it is right side up. But when it zooms in on him is when it is actually upside down.
 * In the song City of Love, Phineas and Isabella were under the Eiffel Tower in the second verse, but Ferb was still on the scooter with Vanessa on his following line. That would mean Phineas and Isabella made it to the Eiffel Tower on foot faster than Ferb and Vanessa with the scooter. However, this could be explained if Ferb and Vanessa went to other places before going to the Eiffel Tower.
 * The sailors claim there were 5 kids on the boat, but there were 6: Phineas, Ferb, Candace, Isabella, Buford, and Baljeet. (Although, he probably didn't count Candace, seeing as she's a teen).
 * Isabella mentions Phineas time traveling twice. However, at the end of "Phineas and Ferb's Quantum Boogaloo," Isabella's meddling with the time machine causes the trip to the future taken at the beginning of the episode to have never occurred, so technically, they only time traveled once. However, this could be explained by counting the second time as the resulting trip they then wound up taking on the same day they built the "Rollercoaster."
 * When Phineas says to Candace "Yeah but we still have this rubber band made with super special density" he was missing a stripe from his shirt.
 * The "Big fat ox" that's on the island is a musk ox. Musk oxen are native to arctic regions and would never be found on an island in the Atlantic especially since there is palm trees on the island which is usually native to tropical regions.
 * The pronunciation of Chaka Khan is messed up at the end when they were telling Candace about it
 * Towards the end Isabella is shown wearing a watch although it did not appear in the rest of the episode.
 * Isabella says there's 58 seconds until sundown, but the time between when she said that and when they get to Phineas's backyard is 87 seconds in real life time.
 * During the song "Summer Belongs to You", there are a lot of mistakes regarding placement of objects and characters. For example, during the song, Buford pushes the roller-coaster car up to the stage. Phineas and Isabella jump out and go to the mics. Ferb is still in the car. Phineas goes to the second microphone, and Isabella goes to the third. They sing the beginning of the chorus, Summer Belongs to You!. However, in the very next frame, Phineas is at the first microphone, Isabella is at the second, and Ferb suddenly appears from nowhere on stage at the third.
 * During the song "Summer Belongs to You", Isabella's tambourine turns invisible for one frame.Isabella's_missing_hair_error.jpg
 * During the song "Summer Belongs to You", Isabella's hair becomes shorter for a second.
 * At the big cast shot at the end of "Summer Belongs To You", Pedro (a minor character) appears twice, one at the bottom left and one and the top left.
 * In this episode, Candace says that she didn't have international coverage on her cell phone, but in A Hard Day's Knight, she is calling Stacy from England.
 * When the Sun-Beater 3000 crashlands in Paris, Isabella and Vanessa are not seen in the plane.
 * After Ferb shows everyone the map on the island, Phineas says that they only have 11 minutes, but the Mid-Atlantic is 3 hours ahead of America, so that meant they actually had 3 hours and 11 minutes.
 * Buford said that the Pacific Ocean is his 5th favorite ocean. There is only four oceans not five (he could have meant fourth favorite).
 * The camera points at the sunset when Isabella is talking to Ferb about it on the island, but the sun is actually rising.
 * When Doofenshmirtz is holding his GPS upside-down, he says 'According to this SPG...' If the letters GPS were turned upside-down, they would look nothing like SPG. The same applies with Paris and 'Sirap'.
 * In the morning, Phineas mentions that it's the Summer Solstice. However, the day before that he said that summer was almost over. Since the Summer Solstice is in June, summer should have just started.
 * In the song Summer Belongs To You!, when Phineas and Isabella are switching places, the color of the sole of Phineas' shoe becomes transparent.

 * Major Monogram's mouth being moved by someone's hand to make him talk was seen again. First was by Carl in ("Let's Take a Quiz")
 * Buford saying "I want the bug" may be a nod to the line "I want the mud" in ("Jerk De Soleil").
 * Vannesa asks Candace what the name "Ferb" is short for. ("Vanessassary Roughness")
 * Ferb folding the giant map to pocket size could be a reference to the time he unfolds a giant blueprint, or when the Wrapped-Up-In-A-Nice-Little-Bow-inator shot their landing pad and it folded up into a tiny parcel. ("The Ballad of Badbeard", "Invasion of the Ferb Snatchers").
 * 3 references to "Swiss Family Phineas":

 * Second time a French to English dictionary is shown ("I Was a Middle Aged Robot").
 * The road construction is later seen in "Phineas' Birthday Clip-O-Rama!" and Candace jumps over it.

Allusions

 * Around the World in Eighty Days - Buford bets that Phineas and Ferb can't fly around the entire world in just 40 hours. Also, Isabella is trying to show her affection to Phineas the same way as Aouda tries to with Phileas Fogg, also implying that maybe Phineas will only realize his feelings for her after she admits it first. As Phineas suggests that Buford return everybody's bikes if he wins, a gent in Victorian garb, possibly Fogg (?), describes an antique bike, called a penny-farthing, with "an unusually large front wheel". It should be noted that Phineas was named after Phileas.
 * During "I Believe We Can", one of Clay Aiken's lines is " ... and that's the measure, the measure of a man!" This is a reference to his own album, Measure of a Man.
 * E.T. - Phineas, Ferb, and their friends go up a ramp and appear to fly on bikes, a reference to the famous scene in E.T.
 * The jump-roping robot's statements "I jump, therefore I am" and "I dangle, therefore I am" parody Rene Descartes's famous philosophical statement, "Cogito, ergo sum" (I think, therefore I am).
 * A sight gag early in the episode parodies on-screen graphics or "bugs" which frequently appear on television stations to identify the network or show being watched or to advertise upcoming programs, a process often considered by viewers to be annoying and pointless.
 * Buford denounces Phineas's scientific reasoning by describing it as "your sorcerous ways", which is the same term Motti uses when denouncing Darth Vader's belief in The Force in Star Wars Episode IV: A New Hope.
 * The anime-inspired dance sequence in Tokyo parodies a popular internet meme turned music video, "Caramelldansen". The final scene of the sequence, where Isabella is shaking a leek, parodies "Loituma Girl" (aka "Leekspin"). Both scenes involved an anime character looped to a short music clip.
 * The revelation tarps resemble famous statues. The one hiding the plane is the Statue of Liberty]], and the one hiding the diorama is Discobolus.
 * Isabella's line "We'll always have giant plastic baguettes" parodies "We'll always have Paris," a famous line from the classic film Casablanca.
 * Before he launches the boat from Paris, Phineas list their situation like a well known quote from "The Blues Brothers".
 * One of the sailors finds the kids' "baguette boat" reminiscent of Karen Johnson, perhaps a reference to the sailing champion from Canada.
 * SpongeBob SquarePants - While stranded on a desert island, Phineas finds a square yellow kitchen sponge and a pink starfish, and says "Look! A sponge and a starfish! There's gotta be something we can make out of this! No, that's ridiculous." which is most likely a friendly jab/reference to its arch-rival animated series. Dan Povenmire worked on the show before developing Phineas and Ferb.
 * Doofenshmirtz's line to Vanessa "You have all the traveler's checks!" is a parody of the famous American Express traveler's checks commercials starring Karl Malden.
 * A mime can be seen in two scenes releasing a red balloon into the air, paying homage to the popular French short film, Le Ballon Rouge (English: The Red Balloon).
 * My Fair Lady - During the song "Summer Belongs to You," Phineas says to Candace, "By Jove, I think she's got it!" This is an exact quote from the famous musical.
 * Hairspray - Summer Belongs to you is in the tune of You Can't Stop the beat from the musical and its remade movie
 * Killing Zoe - Jeremy tells Candace that he had a dream with her about Dixieland music and an iguana playing an oboe. This may be a reference to the movie Killing Zoe which the main characters in France don animal masks and do drugs while listening to Dixieland music in an underground bar.
 * "Ah, there's the rub" is a famous line from Shakespeare's Hamlet, specifically the "To Be or Not To Be" speech
 * Raiders of the Lost Ark - When Candace and Vanessa are running to the plane with a huge snowball chasing them they are yelling "Start the Plane! Start the Plane!" Exactly the same as when Indiana Jones was being chased to the plane at the beginning of Raiders of Lost Ark.
 * Madagascar: Escape 2 Africa - Phineas digging mimics the scene in the film when all the animals dig drying to find water after the river goes dry. Also, after Candace calls Buford a big, dumb ox, she says "Not you big fat ox, him big, fat ox", pointing at an ox. This may mimic when Marty the zebra says "Not you stupid" to another zebra and says "Him stupid", referring to Alex.
 * Back To The Future - At the beginning of Act 2, the background music sounded similar to the main theme from the Back to the Future movies.
 * Alvin and the Chipmunks - Candace calling Jeremy at 2 in the morning while he's in Paris is similar to when Alvin calls Dave in The Chipmunk Adventure, including the caller saying that they were aware of the time difference when questioned about it.
 * Zoolander - Candance yells out "Have I taken crazy pills?" when Phineas and Ferb prepare to escape the island with their giant paper airplane. This may be a reference to when Mugatu ( Will Ferrell ) says "I feel like I'm taking crazy pills."

Other Disney media

 * Baljeet and Buford share the same strand of spaghetti and nearly kiss, parodying an iconic scene in Lady and the Tramp during the song "Bella Notte".
 * When Vanessa and Ferb are riding around Paris, it is similar to the movie Ratatouille when Colette and Linguini are romantically riding through the streets of Paris.
 * When Phineas, Ferb, Candace, Isabella, Buford, and Baljeet say "I believe!" is similar to the characters yelling "I believe in fairies!" to revive Tinker Bell in the original Peter Pan play.
