A skateboarding principal offers unusual incentives to his students to motivate them to learn more. Principal Klutz was hanging upside down from the school flagpole! He kissed a pig on the lips! He painted his bald head orange! And now he wants to bungee-jump off the roof of the school, dressed like Santa Claus! In fact, all the grown-ups at A.J.'s school seem to have something wrong with them. What's going on here? What are A.J. and the kids in his class going to do? They've got to help Mr. Klutz before he ends up hurting himself. Never before has school been this mixed up -- or this much fun. Popular author Dan Gutman pulls out all the stops for this right-on second-grade hilarity. Oh, by the way, A.J.'s teacher, Miss Daisy, is off the wall too. Be sure to read Miss Daisy Is Crazy!
