I teach elementary school and collect books of clean jokes for kids. You had to guess Leno's book would be funny, but the way he talks to kids in the intro is perfect: not talking down to them but right at them, and you are getting the best joke-telling advice in the world. (I would actually read a whole book on his life based on the readability of his intro. Is an autobiography available?) And the jokes are hilarious! Something for everyone in here. These are kid jokes that actually make adults laugh.
