Dav Pilkey started writing the Captain Underpants stories while he was still at school. His books contain scenes which may be too silly for grown-ups, small animals and some types of houseplants. If you are a grown-up, a small animal, a houseplant or a teacher, you should seek permission from a kid before reading on! He is also the author of two series for younger children, Ricky Ricotta and The Adventures of Ook and Gluk. He lives in Washington State, USA with his wife.
