They come in all shapes and sizes, the big, the wobbly the small… ... insists a teacher, reading from a book called The Book of Things That Are Definitely Not Funny. In this hilarious picture book, join a class of children as they attempt to keep a straight face while learning about bottoms. But after the teacher has described ants in pants, ninja farts and torpedoes in the bath everyone is rolling around laughing. What will the headteacher say?! A fabulously silly story with hilarious illustrations – children and their grown-ups will love reading and giggling along.
