I liked the book The Joke War by Gene Inyart Namovicz. It is about two cousins named Charlie and John playing practical jokes on each other. Then they decide to have a joke war to see who can pull the wildest trick. Charlie plays only one trick. He booby-traps the toilet with firecrakers. Some of the jokes John plays are better, like putting egg yolks in Charlie's shoes and putting vaseline on his comb and super glue on the phone receiver. This is a great book even though it has no pictures. Sometimes I laughed so hard I couldn't stop for 3 or 4 minutes.
