Template:Spoilerstart The episode starts with the Wattersons visiting Elmore Junior High on a Saturday. Gumball asks why they are there, so Richard excitedly explains that Saturday is club day. He happily rushes off to his Fantasy Club and leaves Gumball with Nicole.
Gumball asks his mother if he could join her club, but she explains that she becomes a different person when she's in her Anger Management Club. Mr. Small, who's either the president or at least the adviser of the club, greets her, but she suddenly lashes out at him for no reason and sends him flying through the door, knocking him unconscious.
Gumball then attempts to join his sister's Physics Club, but Anais denies him entry since he's not very intelligent. Darwin offers Gumball a chance to be in his Synchronized Swimming Club. However, Gumball can't swim, so they have to deny him entry for his own safety (to which Gumball says "fair point").
Gumball tries joining the Football Club with Banana Joe and Tobias, but the club only consists of them hitting each other with wet towels, taking showers, acting sporty and high-fiving each other. Hector, who's on the actual football team, comes into the locker room and tells them that their team lost, after which he strikes them with a massive towel. Gumball then tries to start his own club, which consists of only him. It doesn't work out, so he disbands it.
