Knock-knocks are a perennial favorite with youngsters, and here are hundreds to keep them giggling. This new collection of uproarious knock-knocks will take kids (and their unwitting victims!) from A (Knock-Knock. Whos there? Ammonia. Ammonia who? Ammonia little kid, so I cant reach the doorbell!) to Z (Knock-Knock. Whos there? Zoe. Zoe who? Zoe doesnt recognize my voice now?). With fantastic drawings that add to the fun, this pocket-sized volume will soon have you bursting at the seams with laughter!
