Packed with kid-tested jokes and riddles, this funny novel is also a thoughtful exploration of the power of laughter to hurt--and to heal. Bobby is the class clown. He can always be counted on to crack up his friends and sometimes even the teachers. But he can't always be counted on to stay out of trouble, and that's no joke when you're in danger of being shipped off to a special school for kids with "behavioral problems." Bobby's got one last chance to prove to his teachers, his principal, and his parents--especially his super-sarcastic dad--that he can be taken seriously. His assignment: to put on a school-wide laugh-off. It's teachers vs. students, and may the best comic win. It's also a chance for Bobby to show his dad that mean jokes aren't just kidding around.
