Professor Pippy P. Poopypants may be the greatest scientific genius the world has ever known. Unfortunately, he has such a silly name that nobody takes him seriously! He´s been laughed out of every major university in the world.In fact, the only place that´ll hire him is Jerome Horwitz Elementary School. Hopefully, nobody at the school will laugh at his name (or make a comic book about him).......Because if just one more person makes fun of Poopypants, it might just drive him OFF THE DEEP END!Needless to say, George and Harold poo-poo Poopypants´s pride -- practically pulverizing it to pieces -- and, hence, Poopypants is preparing to pounce!Step up to witness a brief encounter of the cottony kind. This looks exactly like a job for The Amazing CAPTAIN UNDERPANTS!Jorge y Berto no son malos chicos. Lo que pasa es que les gusta animar las cosas de vez en cuando. Asi, sin proponerselo, estan a punto de hacer que el profesor Pipicaca, un cientifico enloquecido y sin escrupulos que se encuentra a bordo de un robot gigantesco, se apodere del planeta entero. Quien desbaratara los perversos planes de Pipicaca? Un nuevo trabajo para el Capitan Calzoncillos!
