A good impression is sort of a juxtaposition of disparate elements.
I was just never discouraged from doing something wacky like trying to be a comedian.
I pride myself on being tragically uncool.
Comedy is a tool of togetherness. It's a way of putting your arm around someone, pointing at something, and saying, 'Isn't it funny that we do that?' It's a way of reaching out.
It's much easier for me to do an impression of someone real, because you and the audience begin with a baseline understanding of this person's life. And then if you subvert that in any way, it's a little comedy surprise.
It's hard not to be the straight man when Zach Galifianakis is there. He's such a delightfully bizarre creature. Everything he does is so surprising. He's such a live wire. It's just so exciting to watch.
