I write for kids because I think the most interesting (and most humorous) stories come from people's childhoods. When I was writing 'Diary of a Wimpy Kid,' I had a blast talking on the phone to my younger brother, Patrick, remembering all of the things that happened to our family when we were growing up.

To come out and meet kids who have my books in their hands is kind of amazing.

I think if everyone would write down the funny stories from their own childhoods, the world would be a better place.

My life is pretty ordinary in so many ways. I live in a town called Plainville. I have the life of an average dad. It feels like I have this secret identity as an author, and it's still very surreal to me.

On the first day of school, you got to be real careful where you sit. You walk into the classroom and just plunk your stuff down on any old desk, and the next thing you know the teacher is saying, 'I hope you all like where you're sitting, because these are your permanent seats.'

Working with Dav Pilkey was a dream come true. Dav is incredibly funny, and he's been a hero of mine for a long time. It was great bringing the 'Wimpy Kid' and 'Captain Underpants' worlds together!

I can't divorce myself from my childhood. I try to write as much fiction as I possibly can, but there are so many things that are touchstones of my childhood like being on the swim team and playing soccer and the particularities of sports season and environments that make their way into my books.

When kids get stuck on one of our quests, we now have an app for that. It is so cool to know that now kids can use mobile technology to learn more about Poptropica's great adventures and solve its challenging quests.

With the recent addition of a full soundtrack and the players map, millions of Poptropicans around the globe are now fully immersed in a multimedia gaming experience when they embark on our high quality adventures.

When I was growing up, my house was filled with books. My mother was an educator, and my father was a history buff, so our home was a virtual library, covering every author from Beverly Cleary to James Michener.
