The Adventures of Captain Underpants

This is the second funniest book I've ever read by Dav Pilkey. It tells about how George and Harold turned their mean, mean, mean Principal into Captain Underpants. His name was Benny Krupp.

They used a 3D hypno-ring to hypnotize him. George and Harold got into lots and lots of trouble. One time they put frogs in the teacher's Jello. Another time they glued the bathroom door shut. And gluing the bathroom door shut was part of the biggest prank they've ever done. But, Mr. Krupp caught them. He did this by using small video cameras all around the school.
