Gravity Falls has transformed the children of America into an army of Dippers. I couldn't be more proud!

I've always loved The Simpsons, just because it was really, really funny. As a kid, you love the characters. You know that the dad is dumb and frustrated, and you know that the boy is smarter than everyone else around him and is constantly getting into mischief.

I feel like the best kids shows aren't just for kids. The best kids shows have something in it for everyone. As you grow up, you're increasingly proud to be a fan of the show, rather than getting to an age where you suddenly become embarrassed that you ever liked it because it's only for seven-year-olds.

The concern about what's too violent or what's too scary is something that I just completely don't let enter into my creative process. I feel like, if I spend a lot of time trying to worry about whether it will appeal to everyone and who will like it and who won't, and I try to please everyone, I'll just spread myself too thin and lose my mind.

Gravity Falls is a show about mysteries and magic but first and foremost it's a show about characters.

I built a leprechaun trap that was made to look like a tiny hotel. There was a ramp where the leprechaun could walk into the hotel, see a Lego pot of gold on the other side, try to reach it, fall through a trap door, go through a tube, wind up in a biscuit tin, and be trapped. My mom, encouraging my madness, told me that the leprechaun might escape and that I needed a shot glass of whiskey down there to keep him occupied while he was in there.

My goal with Gravity Falls is to make people as paranoid and insane as I was as a child, and I'm delighted to see it's working!
