None - I don't like the cult of the celebrity. I don't think that you can become a celebrity unless you work at it and I don't think that it is an interesting or useful thing to work at.
There are plenty of ordinary people I'd happily go to the pub with. It would also be good to have a chat with talented people who may be well-known but who haven't allowed themselves to be turned into 'celebs'.
I was on a training camp on the Costa Blanca once when Robert Millar was in attendance and I was amused at how many cyclists there were treating him like a celebrity - trying to get him to pose for photographs with them, that kind of thing. He seemed to find the whole thing really tiresome, which is how I think any normal person would feel. I actually would have liked to have had a drink and a chat with RM, but he's not exactly the kind of bloke you ask out to the pub!
