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

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

My freshman English professor at Kent State University in 1984 told me I was a good writer, and she loved all the silly pictures I drew in my notebook. She said I should try writing children's books, and so I did.

My goal with The Adventures of Captain Underpants was to invent a style which was almost identical to that of a picture book - in a novel format. So I wrote incredibly short chapters and tried to fill each page with more pictures than words. I wanted to create a book that kids who don't like to read would want to read.

Encourage kids to be creative without worrying about being perfect.

I had a lot of reading problems growing up.

My reading preferences are kind of all over the board - I read nonfiction, I read graphic novels.

Most kids are smarter than most grown-ups. Kids see the world in black and white... They look through all the garbage and see a world run by fools and dullards and lazy people. And there's nothing they can do about it because they have no power.

It used to take me forever to read and comprehend stuff, so I decided not to make the 'Captain Underpants' books too challenging. Don't get me wrong - the humor and ideas are often sophisticated - but the books aren't hard to read. I wanted kids who hate reading to find these books irresistible.

Try to remember that being unsuccessful in school doesn't automatically mean you'll be unsuccessful in life. Lots of people who didn't excel in school still went on to have successful lives.

Nothing prevents boredom like a good book.

Having a sense of fun in books is a huge, huge deal, because a lot of times kids - even me when I got to third or fourth grade - don't associate reading with fun.
