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 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.
