A lot of the fiction I read growing up was post-war American, and not all of it centers on Manhattan, but around people of the Mad Men generation, people like John Cheever and, in more modern times, Don DeLillo, who I always mention.

I did throw a lot of eggs into one basket, as you do in your teenage years - 'I am buying these records, I am wearing this'. I did quite a bit of that. You have to do it, wear your stupid shoes, wear your stupid hair.

You try various things when you're growing up. I was an attache in the Foreign Service for a while and then I drove a bulldozer, but neither of those panned out for me so it had to be stand-up.

One thing that's coming up a lot is: are you as grumpy as you appear from this Black Books thing.

I'd previously done 'Expelled,' and that was more on the comedy side, so I really wanted to challenge myself and see if I could actually do a drama.

I never looked at my future as comedy. Even at Second City, I always thought of it as acting. I knew I was going to be an actor financially, emotionally, egotistically.

The script for 'Infamous' was so poised between tragedy and comedy. It's a dream part. One reads those scripts with a sense of melancholia. When you read a script that good... I remember thinking, 'Oh, this script is too good. They'll never give it to me.'

With a live audience, it's very clear when you've pushed it too far to the edge - because you fall off that edge and hit bottom with a thud. Nothing abstract about that. You know you went too far when you hear that groan or worse - that silence instead of the big laugh you were expecting following your hilariously edgy joke.
