After a gig I always head back to the hotel, remembering granny's words of wisdom. I cancel the late-night pizza and watch the Jonathan Ross show instead.

Politics is pop. Our job as comedians - especially me, as a late-night talk show, which is a broader audience - is to amplify what we think America is thinking.

Staying in luxury hotels still gives me a kick, especially Oulton Hall in Yorkshire. I'd stay in a hotel for the breakfast and room service.

The truth is, we have this idea that late night is about creativity and being cool, but that's not our job. Our job is to get as many people watching the commercials in between our show. That's the reality of it.

I know there are, like, 12 rules for late night: a desk, a band. Will people take me seriously if I don't wear a tie?

I've always loved David Letterman. There was an irreverence to his show that I remember, especially in 'Late Night' - it always seemed so fresh.
