 Goaded by his local rival, TJ challenges Blimpy s manager, Ivor Willis, to an inter-restaurant quiz. Before long, there are both reputations and large amounts of cash at stake. TJ is confident that with Lily s brains they will walk the competition, but disaster strikes when Lily is called away due to her grandmother s illness. The Spatz team then recruit a very boring, but highly knowledgeable, eccentric academic, Professor Billy, to be a ringer for their side. However, they don t bank on the professor defecting to the Blimpy s team. It looks like all is lost, but it eventually emerges that Stanley was paying more attention to Professor Billy than anyone else, and comes up with the winning answer.
