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 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 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.

In terms of creative engagement, I just love being able to produce, produce, produce. You don't always get it perfect, but it has much more of an improvisational element, and you learn.

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'm a very relentless individual and have a lot more insanity coming.

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!
