When Lucy enters a TV Quiz Show, Old Tom helps her study. However, Billy is one of the other contestants and, on the day of the show, he tricks Lucy into catching the wrong bus. When Lucy doesn't turn up at the TV studio, Old Tom - who is in the audience with Angela - rushes onto the set and takes Lucy's place in the quiz. Because he helped Lucy study, Old Tom knows most of the answers. However, Billy is cheating and nearly wins, until Old Tom accidentally drenches him and washes off all Billy's cheat notes. On the last question, Billy can't cheat any more, but Old Tom gets the answer right…and wins the contest.
