George and Harold have probably gone crazy. Coffee Commodes transported them to a wacky place where the teachers are always kind, the cafeteria serves delicious food, and the school principal, Mr. Krupp, finds them funny. Something is very, very wrong - and it gets even worse when their evil doppelgängers kidnap their pet pterodactyl, Crackers, and Sulu, the Bionic Hamster.
