Pete Davidson and Dav Pilkey on "Dog Man"

It's hard to believe, but as author and Illustrator Dav Pilkey recently told students at Boy's Prep in the Bronx, he created Dog Man back when he was in second grade. "He looks a little bit different," he said.

The kids loved hearing when someone with learning disabilities ("I had ADHD, and I was dyslexic, and I was the class clown, and I couldn't sit still," he said) could go on to be so successful. 

Every book in Pilkey's Dog Man series has been the bestselling children's book for the year it came out.
