In real life, Josh [Gad] is a different kind of lovable idiot. In real life, he's a much filthier idiot. He has a dirty sense of humor.

Josh Gad and I have been friends since the time he auditioned for Modern Family. I directed the pilot for that, and that's how we met.

It's funny because The Book of Mormon is The Book of Mormon now. When I was doing it at the very beginning, and I was a part of it for four years and always believed in it, I never really knew if it was going to be more than a convention for South Park fans.

There are certain TV shows that probably would have made me rich, and there are certain commitments I could have made that probably would have raised a lot of eyebrows that I didn't. But I don't look back at those decisions and say, 'Oh God, I'm such an idiot.

I was like a Borscht Belt comedian trapped in the body of a 6-year-old. I was channeling Jackie Mason at 7.

Josh [Gad] is such an amazing improviser and is so good when the material is flowing from him that sometimes, if a written scene isn't working quite right, I'll tell him that we've got it and that he can just play. He'll blow us away with some super weird stuff and some wild things that we might use bits and pieces of in the edit, and then I'll say, "Just for good measure, let's do one more of the scripted version."
