Query: YUCK! PLAY CLAY!

I love this book. In true Munsch fashion, the reactions of the parents (and eventually kid) eating play clay cookies are incredibly over the top and hysterical. They gag, they scream, they brush their teeth a zillion times. And of course Christopher learns his lesson because, as we all know, turnabout is fair play.There's no real moral to this book, it's just a bit of fun.
