Even Stevens (2000) : 1x3

Louis wants to enter the school talent show and do his comedy routine but he waits too long and misses the entry deadline. He tries to get Ren to let him share her spot in the show with him, but she has no sympathy. At dinner Louis gets his parents to pressure Ren into doing an act with him, much to her annoyance. They do Louis' act in rehearsal and it gets a lot of laughs. Larry Beale sees this and doesn't like it. He tells Ren that she's just being her brother's flunky in the act and that he keeps all the good lines for himself. Falling into Larry's trap, Ren gets mad at Louis and quits the act. When the talent show comes around, Larry and his partner Ivan go onstage before Louis and steal his act. Louis is crushed now that he won't get to do the one thing he felt he was really good at. Ren takes pity on him and at the last minute they come up with a comic opera routine that wins the brother and sister first prize.
