"Brain Drain" is an episode of Phineas and Ferb. It premiered on Disney Channel on October 29, 2010 and on Disney XD on November 6, 2010.


Phineas, Ferb and the gang are all sick, so they decide to make it the best "sick day" ever by creating a live television feed to their friends' homes so that they can all enjoy a day of fun together. Meanwhile, Vanessa learns from her mom, Charlene, that her dad is picking her up from a party she is going to with her punk rock boyfriend Johnny and she worries that he will embarrass her yet again. However, Dr. Doofenshmirtz is busy trying to use his "Devolition-ator" to drain Agent P's will power so that he can control him. Things get out of hand when Dr. Doofenshmirtz picks up Vanessa at the party, and it's up to Agent P to save the day.


Candace on having the best sick day ever.

Linda is about to leave while Phineas and Ferb are sick in bed. Before leaving she asks if they'll be fine by themselves. They both state that they will be fine. They both say bye to Mom. Shortly afterward, Candace comes in and asks if they are sick. Phineas optimistically tells Candace not to worry, sneezes, and then replies that nothing can stop them. Candace happily thinks about Jeremy related activities out loud, and leaves.

She does not know that they have made a system with their friends so that they can talk via microphones and a television screen. Isabella greets them with her catchphrase, and then sneezes. Both Baljeet and Buford come on, and they all cough and sneeze except for Buford. Buford says he is not actually sick, just lazy. Phineas wonders where Perry is, and everyone looks in their beds.

Perry walks past Phineas and Ferb's room. He stands up and puts on a surgical mask. He walks on two legs across the door. He walks on all fours again and puts on his fedora. He goes to his lair. Major Monogram makes a comment about the surgical mask, and Carl adds his thought. Perry takes off the mask and Major Monogram starts the briefing. He says Dr. Doofenshmirtz has been making purchases at Brain Bath & Beyond. Perry leaves in his hovercraft. The Flynn-Fletcher family van and the driveway open in half and closes again.

Perry arrives at Doofenshmirtz Evil Incorporated. He walks to a chair with an empty table. He hears Dr. Doofenshmirtz's voice but he sees no one. Dr. Doofenshmirtz swings from a rope and puts a helmet on Perry's head. Dr. Doofenshmirtz tells Perry he can control his actions with his new invention: the "De-Volitionator" which was, according to him, "not to be confused with the "De-Evolutionator" from "a few schemes ago". Dr. Doofenshmirtz makes Perry get off of the chair and walk towards him then explains that volition is the power to choose what he is going to do.

Meanwhile, back at Phineas and Ferb's room, Phineas and the kids are about to play a video game. The first round is Buford verses Isabella. Buford knocks Isabella down. She stands up and gets her sash. She ties him up and pulls, sending Buford spinning away.

Vanessa is in Charlene's car. She is on her way to a party at the Danville Scrap Yard, and she is talking about her Dad with Charlene. In a flashback, Dr. Doofenshmirtz is seen picking up Vanessa from school in a tricycle with a wagon tied to the back. He is wearing a diaper and baby hat. The other students laugh as Vanessa gets in the wagon. Back in real life, they arrive and Vanessa greets Johnny. Charlene leaves.

Back in Phineas and Ferb's room, they start their next round: Baljeet and Ferb. Baljeet complains that Ferb is the Gaming World Champion and he would easily lose. Ferb runs toward Baljeet, and Baljeet kicks him. He punches Ferb, who loses. Baljeet asks if he intentionally let him win because he didn't want to hurt his feelings. Showing a pendulum duck hitting the forward button, Ferb replies, "Oh, I'd never do that," while reading a book.

At Danville Scrap Yard, Vanessa and Johnny are at a party. There are cameras set up to record everything; including themselves, the crowd, the DJ, and the toilets. In Phineas and Ferb's room, Phineas wonders who he will fight, either Isabella or Baljeet. The next round is Phineas verses Phineas. Because he is playing both of himself, they kick each other, and fall to the floor. He exclaims that he is "kicking his own butt."

Dr. Doofenshmirtz is walking Perry to Abzir's Car Parts. He makes Perry dance around. He then makes Perry slap himself. Afterwards, he makes him pick up a piece of gum from the floor to put it in his mouth. Before it gets in his mouth, Doofenshmirtz stops Perry, then decides it was so funny he makes Perry put the gum down to do it again. From the park, Doofenshmirtz calls Vanessa at the party. He says that Perry the Platypus almost ate gum off of the sidewalk. He also tells her that he will pick her up along with her Visigoth friends. Vanessa corrects her father, telling him that the name is Goth, not Visigoth; and that her friends are Punk, not Goth. Vanessa hangs up, and Dr. Doofenshmirtz talks to someone dressed as a Visigoth barbarian. The barbarian leaves, disappointed that he doesn't get to go to the party. Dr. Doofenshmirtz returns to making Perry slap himself.

Perry the Platypus about to eat gum off the sidewalk.

Perry is pushing Dr. Doofenshmirtz in a shopping cart. They arrive at the Danville Scrap Yard. The remote's battery is low so Dr. Doofenshmirtz tried to plug it into the battery running the party's cameras. However, it does not work and the resulting electricity is sent through the power lines to the Flynn-Fletcher house. On Phineas and Ferb's video game, instead of seeing Phineas and Buford fight the signal from one of the cameras shows Perry and Dr. Doofenshmirtz on screen. Phineas realizes that he can control Perry's left arm with his game controller. Isabella can control his left leg. Buford can control his right arm, and starts making Perry slap himself. Ferb can control his right leg, and Baljeet can control his forward and backward movement.

Dr. Doofenshmirtz is annoyed that he is no longer able to control Perry, and tries to kick him. The kids think Dr. Doofenshmirtz is a game villain boss and control Perry to fight him in the "Perry level." Buford has made Perry catch a fly and eat it thinking that it is a power up. Dr. Doofenshmirtz says the fly that Perry ate was worse than the sidewalk gum he almost ate earlier. Isabella made him hit Dr. Doofenshmirtz. He gets scared and runs away to climb one of the scrap piles. Phineas knocks him down. Dr. Doofenshmirtz tries to hit Perry with an umbrella, but Buford uses Perry's right hand to stop it and steals it from him. Isabella makes him jump and hits Dr. Doofenshmirtz with the umbrella. Phineas tells Ferb to kick him off. He does make Perry kick him off, which causes him to roll down the pile. Ferb blows the game controller. Phineas claims the right to throw Perry's hat in the air, removing the helmet and it lands on the camera. They lose the signal, and everyone groans.

"There's a Platypus controlling me."

Dr. Doofenshmirtz is rolling down the pile and gets his hands covered in glue. He lands on the DJ controls for the party. As Dr. Doofenshmirtz stands up, he puts his hands on it. The music stops and everyone is silent. Johnny asks Vanessa if he is her Dad, and she replies that he isn't. Someone comments, and the crowd boos him. Perry starts to leave but he sees the crowd booing at Dr. Doofenshmirtz and feels bad for him. Perry gets Dr. Doofenshmirtz's attention and puts the mind control helmet on him, making Dr. Doofenshmirtz scratch the records. He starts singing a rap about a platypus controlling him. The crowd likes it, and decides that the platypus is a metaphor for the things that control them. He tells them that it is not a metaphor, in song form. He realizes that Perry has left, and looks to see Perry giving him a thumbs up. Johnny tells Vanessa that her Dad is cool. She responds "You're my punk rock boyfriend. You're not supposed to think my Dad is cool." She walks up to Dr. Doofenshmirtz, and says "It only matters that I think he's cool." She kisses Dr. Doofenshmirtz on the cheek, and Doofenshmirtz says "She thinks I'm cool!" and everyone cheers.

Phineas and Ferb are still in their room and Phineas replies that all their fevers are broken while Buford got sick from lying in bed all day. They see Perry come in. Phineas comments about giving him a walk, and Perry chatters wearily.




  • Carl says he fears the smell of garlic, but in "Ain't No Kiddie Ride", he mentions that he was born without nostrils.
  • When Dr. Doofenshmirtz first has his hands on the record, he has his hands on the record from top to bottom. Therefore, he should not be able to scratch the record. However, it is shown that he can lift his hands barely. That may be the reason he is able to scratch the record.
  • When Phineas battles himself, the health bars say "Phineas." But when Baljeet battles Ferb and Isabella battles Buford, the health bars say Player 1 and Player 2.
  • Doofenshmirtz puts the Devolition-ator over Perry's fedora, but when Phineas makes him remove the Devolition-ator, Perry is not wearing his fedora. Perhaps it was removed with the Devolition-ator.
  • When Perry puts the Devolition-ator on Doofenshmirtz after he accidentally stops the record, the rap song starts before Doofenshmirtz starts DJ-ing.
  • When Doofensmirtz was falling down the junk pile, Perry is seen wearing his fedora. But when the shot goes back to Perry, he is still wearing the Devolition-ator, and when Phineas makes him remove it, the fedora is not there.
  • During the song, Perry is clearly hiding under the table and to Doofenshmirtz's left. But when he looks under the table to motion to the "platypus controlling me," he looks to his right.
  • At the end of the episode, Phineas is shown with one more lock of hair then normal, of course he could've just grown for one day and then got it cut.
  • Linda had left to get groceries. Therefore, her car would not have been in the driveway when Perry exited his lair.
  • In the closed captions, Carl's name is misspelled as "Corro."
  • Despite of the fact that Charlene's car is a 1973 Chevrolet Camaro, the jingle says "Sports Sedan." The Chevrolet Camero has never been sold as a sedan.
  • Because the Devolitioninator fits Perry, it therefore should not fit Doofenshmirtz.
  • When Doofenshmirtz says "platypus power," his mouth is not open.
