I think the culture of Civil War re-enacting is also incredibly fascinating.

It's just one of those things like when you're not supposed to laugh, it makes it that much harder to stop laughing. And for some reason Zach [ Galifianakis] and I get in this feedback mood of giggling, and on the set of Hangover we just couldn't get through stuff.

All I knew is that I loved movies and comedy and TV, and I wanted to perform. I made a bunch of shorts and movies in college, and that was always fun too. I directed some plays in college. It was taking it all in and trying to immerse myself in as much of it as possible.

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.

The scene [in The Hangover] where the tiger actually pops up behind us, that's actually a Jim Henson tiger puppet. The Jim Henson Company actually supplied that tiger. And it's really cool. Its entire face moves. It has like all these little motors in its eyebrows and cheeks and mouth. It was amazing.

I loved the show Lost, in part because the writers were so nimble in how they would take things from previous episodes, that probably weren't created with any intent towards a larger narrative, and they would get woven into narratives in a really elegant and exciting way.

I told personal stories the way [Bill] Cosby would spin a yarn for ten minutes. I think in hindsight it works better as a long story than as a condensed monologue.
