You know what? What? Chicken butt! The classic schoolyard joke has been recast as an irreverent picture book, with call-and-response parts for parent and child. The word repetition in Erica S. Perl s text, and wonderfully comic illustrations by beloved artist Henry Cole, make this a particularly inviting book for new readers, as does the opportunity to "trick" a parent or other adult into participating in a very silly joke. The humor builds to a surprising and satisfying conclusion. Warning: Kids will want to read this one over and over and over again!
