you're a highschool student getting bullied by the bully Dave one day you decide to get a revenge on him so you sneak into the changing room before the game starts

You:"okay now just to find his locker..."

You find Dave's locker and open in you then take the water bottle and slip some bladder empty pills

You:"that should do"

You hear someone's coming so you quickly sneak out when you look through the key hole you see it's Dave drinking the water

You:"yes!"

You go to the audience to watch the game after 15 minutes you can see dave really desperate to pee when suddenly he starts to wet his pants

Everybody on the audience bursts laughing and Dave runs to the changing room in tears when you quickly follow him

You see him sitting on the bench touching his wet pants when you get closer to him holding a babyish diaper

You:"tsh tsh tsh Dave not so big for potty training"

Dave:"shut up! It was one time i bet it's your fault!"

You:"maybe but for now lie down so i could put this diaper on my new baby"
