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.

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

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.

Working on The Daily Show, I co-produced all those field segments, and that's another huge thing.I probably did more than 100 field segments.

I have profound respect for Sacha Baron Cohen, but Borat is not a particularly comfortable movie for me to sit through.

It's a fascinating culture [the South in the Civil War period] and so rife with comedic possibilities. And not in a way that...I have no intention of making fun of re-enactors. I think it's more just a celebration of their passion and enthusiasm, which is so infectious and maybe at times a little misguided.

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.
