So begins the dialogue between a tired bear dad and a rambunctious bear cub who would rather play with his tighty whities than get into bed. Underwear makes great hair. It can even turn one into a superber, or a goggle-wearing swimming bear. But beware of a big scare! Rhymes, homonyms, and conjunctions abound in this book that could be used to teach reading, but its primary purpose is to make bedtime fun.
