I happen to think singing is hilarious, especially when it pops out at the wrong time.

When we were not shooting [The Hangover] we were sleeping, so pretty much every waking moment we spent together. And, you know, Bradley [Cooper], Zach [Galifianakis] and I were acquaintances before the movie started but we became good friends very quickly and spent so much time together that it was just inevitable we were either going to really hate each other or really like each other. Thank god it turned out to be the latter.

I worked as an assistant editor, actually, for a few years. That was right when I was just starting to get out at night and do a lot of stand-up, improv, and sketch work in New York. It really is invaluable. I think it pounded into me an awareness of what an editor wants and needs, in terms of clarity of a moment, where and when to start and stop a line.

People now genuinely respond to it and associate me with music. It's really fun.

You take a vacation to a place like Thailand and you're ready for the excitement of something new and foreign. But when you're working 14-hour days, all you want is something familiar to ground you. And there's just nothing there.

I have profound respect for Sacha Baron Cohen, but Borat is not a particularly comfortable movie for me to sit through.

The Daily Show was an incredible training ground for that kind of thing. It was all about discipline and generating material constantly.
