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.

I absolutely love television. What's so great about TV is that I can tell 20 stories in a year. If I was working at a feature studio, I'd tell 1% of someone else's story, over the course of four years.

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 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.

When you're doing an animated series, you tend to pitch storyboards. You write a script and then you draw a comic version of that script and put it up on big boards, and then you pitch it to a big room of executives and writers.

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.

If you ask anyone in animation, how long they've been into animation, they'll pretty much always tell you that it's since they can remember, and I'm no exception.
