Gary and Wyatt want to win the school talent show. How do they go about winning? Simple. They get Lisa to create a magic book that lets them do real magic tricks. The guys can now slice people in half and create demonic creatures that come from hell. (The slicing in half tricks lead to Chett getting an eye-full in the bathroom, when he walks in on Wyatt's lower half using the facilities.) Principal Scampi enjoys the boys' show so much that he asks them to perform at a dinner party he's hosting. Principal Scampi has a great idea for the grand finale- the guys can chop off his head! The only problem is that the magic book has been ruined and there is no way to reverse any of the magic that the guys use.
