When you're playing a fictional character reacting to the real world, it's incredibly difficult and confusing and kind of messes with your values a bit.

Improvisation is about finding the best joke or the silliest way to get something across. Improvising conflict is always fun because you can just go for it.

We spent six weeks there [in Vegas]. The only thing crazy that I did was shoot that movie [The Hangovers]. The stuff in that movie is way crazier than anything I might have done, drunk one night in Vegas. I mean we did it for real in the movie, so that's as crazy as it got.

Don't be afraid of fear. Because it sharpens you, it challenges you, it makes you stronger; and when you run away from fear, you also run away from the opportunity to be your best possible self.

Sometimes you just create a joke out of thin air in the editing room. So I'm really glad I've had that experience. It gives me a little more confidence in front of the camera.

Vulnerability is huge. I love to see that in characters. It's something I feel like a lot of my comedic heroes have always done.

A lot of kind of like the way that Andy [Bernard] talks, you know, the writers pick up on those things - little moments that I inject and then they start to write it in later. It's hard to say if a whole storyline is spun out of an improv. I feel like it has happened on The Office, I just can't think of it.
