I very much enjoy things like '24,' although I suspect that's run its course.

I used to do prank calls as these people and try to convince certain hoteliers that I was someone else. At the time, I used to do people like Tony Blair and William Hague. It was very good fun hearing people kind of thinking, 'Hmm, is that who I think it is?'

On the whole, when I travel to different countries, I like to find the hidden places, so I tend to avoid the cities - but in terms of the ease of getting about, finding what you need, the excitement, that undercurrent of whatever you want it to be, it's got to be London.
