It has been said that a rolling stone gathers no moss. I would add that sometimes a rolling stone also gathers no verifiable facts or even the tiniest morsels of journalistic integrity.

It's incredible how big a part of my acting career music has become. I get asked about it all the time, and I love it. It's one of my favorite things, and I'm so glad that I get to sort of work that in.

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 was just fooling around with the piano and Todd [Phillips] was like, 'Hey there's a great spot in the movie [The Hangover] where we need a little bit of a breath in the narrative. You should write a song and stick it in there.' And I was like, 'Well, what should the song be about?' And he said, 'The tiger.' 'Oh, okay.' So I went off and I wrote this song. I came back and Todd and I tinkered with it a little more and then we shot it right then. It all happened in a day.

I worked as an assistant editor, actually, for a few years. That was right when I was just starting to get out at night and do a lot of stand-up, improv, and sketch work in New York.

February is a month of months, and there is one special day: Valentine's Day on the 14th. I know it's still a ways off, but I just can't wait. Janice, if you're watching, will you make me the happiest man in the world and get out of my apartment?
