Barry feels threatened when school deadhead Matt starts hanging out with the JTP and soon finds himself kicked out of the group when he becomes too controlling. Back at home, Adam uses a curse word which sends Beverly into a tail spin, even though she curses all of the time. To curb everyone's behavior, a swear jar is created, with the money going to a vacation of the winner's choice.

Barry plans big romantic gestures for Lainey on prom night; Adam is trilled when a nerdy but cute junior asks him out.
