God bless him, I mean a lot of times you get non-actors on a set and they get really self-conscious, especially when doing something crazy like singing along with Phil Collins. They get sort of reserved and self-conscious. Mike [Tyson] completely trusted Todd [Phillips] and totally put everything into it.

I'm a very jaded and cynical person.

I went to Oberlin College, and they don't have a film major, but they do have what's called an individual major, where you can sort of pitch to a committee your own course study, and if they approve it, you have essentially just designed your own major. So Oberlin doesn't have a film major; they do have a film minor... And then my spring semester of my junior year, I went off to NYU film school as a visiting student - they have a program for kids from other schools to come in for a semester.

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

It's incredible how big a part of my acting career music has become. I get asked about it all the time, and I love it. It's one of my favorite things, and I'm so glad that I get to sort of work that in.

I mean they [ Bradley Cooper, Zach Galifianakis] are both just really good guys and also they're both extremely funny in very unique ways. We made each other laugh an awful lot, and that goes a long way. And we also went through some hard times. I mean it was hard to make this movie [The Hangover].

There are certain relationships in our lives that implode, and it can feel really inexplicable and terrifying. You don't know why, and sometimes relationships end for reasons that one person keeps from the other person, and it's just totally unclear, and it just goes south and it's heartbreaking.
