Captain Underpants #1: The Adventures of Captain Underpants book by Dav Pilkey

Pilkey plays with words and pictures, providing great entertainment. The story is immediately engaging—two fourth-grade boys who write comic books and love to pull pranks find themselves in big trouble. Mean Mr. Krupp, their principal, videotapes George and Harold setting up their stunts and threatens to expose them. The boys' luck changes when they send for a 3-D Hypno-Ring and hypnotize Krupp, turning him into Captain Underpants, their own superhero creation. Later, Pilkey includes several pages of flip-o-ramas that animate the action. The simple black-and-white illustrations on every page furnish comic-strip appeal. The cover features Captain Underpants, resplendent in white briefs, on top of a tall building. This book will fly off the shelves.
