That's actually a rare thing to be on a set full of people that you admire and make you laugh all the time.

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].

It's kind of hard to win most elections on anti-family, immorality, and Satan-worship.

Who among us wouldn't rush out and buy a Pepsi if we thought it would make the Osborne's disappear?

The piano song that I do in the movie [The Hangover], it's a great example, that was never - that wasn't in the script.

Let's just say it was damn hard [to make the Hangover]. I've got the bumps and bruises to show for it. It's funny because things that don't even look that bad on screen were still extremely painful.

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.
