Nobody understands why Angeline is so smart. She could read the first time she picked up a book, she can play the piano without ever having had a lesson, and she even knows what the weather is going to be. But being smart is causing Angeline nothing but trouble. The mean kids in school call her a freak, her teacher finds her troublesome, and even her own father doesn't know what to do with an eight-year-old girl who seems to be a genius. Angeline doesn't want to be either a genius or a freak. She just wants the chance to be herself and be happy. But it's only when she makes friends with a boy the kids call "Goon" and the teacher they call "Mr. Bone" that Angeline gets that chance.

'Why did the guy eat two dead skunks for breakfast?' 'Because dead ones squeal when you stick the fork in.' Gary W. Boone knows he was born to be a stand-up comedian. It is the rest of the kids in the class who think he is a fool. Then the Floyd Hicks Junior High School Talent Show is announced, and he starts practising his routine nonstop to get it just right. Gary's sure that this will be his big break - he'll make everyone laugh and will win the $100 prize money. But when an outrageous surprise threatens to turn his debut into a disaster, it looks as if the biggest joke of all may be on Gary himself.
