New York Times bestselling author Dav Pilkey's Captain Underpants soars to greater heights with the
breakthrough fourth book--now in full color!
George and Harold are fourth-grade buddies with a penchant for practical jokes. When the boys' latest prank
drives their science teacher over the edge, their clueless principal, Mr. Krupp, quickly hires a replacement:
Professor Pippy P. Poopypants. Of course, George and Harold can't resist making fun of the Professor's silly
name. But then the Professor retaliates by forcing everyone in town to change their own names to be equally
silly, with colossal consequences!
