Georges et Harold se retrouvent dans un monde ?trange, un monde ? l'envers, o? le directeur de l'?cole a le sens de l'humour, o? la bibliotechnicienne sugg?re de bons livres, o? les profs sont aimables et o? la nourriture de la caf?t?ria ne sent pas les couches souill?es. Mais ils y d?couvrent aussi une autre version d'eux-m?mes, vilain Georges et vilain Harold, qui s'appr?tent ? mettre en ouvre quelques grotesques machinations.

Have George and Harold completely lost their minds? Their time-traveling Purple Potty has landed them in a crazy place where the teachers are always nice, the cafeteria serves delicious food, and the school principal, Mr. Krupp, actually thinks they're funny. Something is very, very wrong -- and it gets even WRONGER when the boys' pet pterodactyl, Crackers, and Sulu the Bionic Hamster are kidnapped by George and Harold's evil-twin look-alikes. Now George and Harold must face their cleverest enemies yet: THEMSELVES Could this be another job for the amazing Captain Underpants?
