     The fifth-grade girls and the fifth-grade boys at Laketon Elementary don't get along very well. But the real problem is that these kids are loud and disorderly. That's why the principal uses her red plastic bullhorn. A lot. Then one day Dave Packer, a certified loudmouth, bumps into an idea -- a big one that makes him try to keep quiet for a whole day. But what does Dave hear during lunch? A girl, Lynsey Burgess, jabbering away. So Dave breaks his silence and lobs an insult. And those words spark a contest: Which team can say the fewest words during two whole days? And it's the boys against the girls. How do the teachers react to the silence? What happens when the principal feels she's losing control? And will Dave and Lynsey plunge the whole school into chaos? This funny and surprising book is about language and thought, about words unspoken, words spoken in anger, and especially about the power of words spoken in kindness...with or without a bullhorn. It's Andrew Clements at his best -- thought-provoking, true-to-life, and very entertaining.

    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.

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.
