"Homecoming Upset" is the eighty-third episode of Kim Possible.
Kim is unable to share in Ron's joy at being crowned homecoming king because newly-single Bonnie cheats her way into becoming queen, and seems intent on making Ron her next boyfriend.
- This episode aired on Will Friedle's 31st birthday.
- We learn that Kim is seventeen years old, or at least was at the time of their Junior Prom, when she says she had to wait twelve years to get a kiss from Ron.
- This calculation would mean more if we knew exactly how old Kim was at Pre-K when she first met Ron.
- Mr. Barkin mentions that Ron Reiger won second place in the Tri-City Science Fair, which also makes him the second known student from Middleton High School to excel in any mentioned science fair, the first being Justine Flanner.
- These facts were also mentioned in A Stitch in Time.
- The eighty-third episode in chronological order.
- The eighty-forth in production order.
- The only episode where Señor Senior, Junior appears without his father, Senior.
- When Ron is on Coco Banana's plane on his way to Venice, he is in his mission clothes. However, when they arrive in Venice, he is wearing his usual clothes. Later, when he is in the boat, he has returned to his mission outfit.
- As he opens the gate to Rotiffle's community, Wade tells Kim, "After you," but he then precedes her through the gate.
- Kim complains that it took Ron "twelve stinking years" to kiss her after seeing Bonnie kiss him. But since Bonnie has been calling Ron cruel names since kindergarten, one year less than Pre-K, she has known him almost as long, at least eleven years.
- JP Bearymore's Pizza Party-Torium has a grand re-opening in this episode because it was destroyed by Motor Ed in "Car Alarm".
- Coco Banana gives Team Possible a ride in this episode to pay them back for their assistance in recovering his stolen designs in "Fashion Victim".
