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.
