When Dav Pilkey was a kid, he was diagnosed with ADHD and dyslexia. He was so disruptive in class that his teachers made him sit out in the hallway every day. Luckily, Dav loved to draw and make up stories, so he spent his time in the hallway creating his own original comic books—the very first adventures of Dog Man and Captain Underpants. Since then, Dav has written and illustrated a number of bestselling and award-winning children's books, including the Caldecott Honor book The Paperboy. His Captain Underpants series and Dog Man graphic novels have sold millions of copies worldwide and have been translated into many languages.
