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!

There is a very specific, unique brand of rivalry that exists between twins. You're always wondering who the Alpha twin is.

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.

A sibling is a friend for life, but they are a friend for life that you are forced to have. And like anything that you are forced to do, occasionally people will drive you crazy.

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.

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 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.
