I'm quite a curious person. I don't mind being the one who doesn't know things, a role I often play in QI.

A foolproof plan for not getting a job - show up for your interview wearing flip flops.

I'm more inclined to linger in the science pages of 'The Week' magazine. But my principle obsessions are still watching sitcoms and football.

The thing I'd really like to see is the old London Bridge, with all the old buildings around it like Shakespeare's Globe. I'd like to walk along that. Don't worry, I won't get drunk and fall in.

I see myself as a comic but the acting helps sell tickets for gigs.

The principle that light can be in two places at the same time is absolutely extraordinary.
