What's a contest without a prize? Aunt Molly has entered a joke-telling contest at a local comedy club, and Cam; her best friend, Eric; and Mr. Jansen are in the audience to watch her perform. The prizes are exciting, but the competition is stiff - there's a prop comic, a knock-knock joker, and more!
As the show starts, Cam notices that one of the prizes, an engraved silver plate, has disappeared. Suddenly, everyone in the club becomes a suspect. Can Cam solve the mystery of the missing prize, or will she be laughed out of the Joke House?
