One of the biggest breaks we had actually, one of the biggest, the hardest I laughed on the movie [The Hangover] was the baby was just doing ridiculous things and making hilarious faces. But I'm sitting there and I'm supposed to be having this exchange with Zach [ Galifianakis] and the baby is like staring at me with these huge eyes and acting, and just making the most cerebral faces, and I could not keep it together.
