I think every character I've ever come up with has been based on someone or something I've known.

I think my funny books are my favorites because I like to laugh so much.

Once I have the story in my head, I write it down. The illustrations usually come last.

I guess I'm the only guy in the world who would listen to those incredibly offensive songs and think, 'Hey, that guy should be making music for kids,' ... But that's what I thought.

Being an author is fun. It's a great job, because I can stay up as late as I want, and if I feel like taking the day off, I do it. Plus, I get to make up silly stories and draw pictures all day.

I had a lot of reading problems growing up.
