I try to be a man of mystery. I try to keep the various projects I'm up to as close to the vest as possible until it's time to reveal them.

I believe that one of the reasons Gravity Falls is such an unusual place, maybe part of the reason that the stoplights switch on and off at random times and cell phones don't get proper reception and compasses spin wildly - is because of the strange kinetic influence of the UFO buried just underneath everyone's feet.

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.

As long as I could hold a pencil, I was drawing and telling stories and making jokes. I've just been lucky that no one ever stopped me, and now I can do that for a living.

Some people could say, "I'd like something that's super dramatic and miserable and made me cry and made me sad forever" but that's not my taste.

I thought that was the coolest thing in the world, the idea of somebody trying to solve mysteries. I would see conspiracies in everything. I think I believed in leprechauns longer than any of my fellow classmates because I tried to catch them.

I think twins can sometimes be shoved into the same mold and they can start to feel like they're not being given a chance to develop their own identities.
