A lot of humour is about just enjoying life and spontaneity and because you make a joke that puts somebody down - we're always teasing each other. It's with affection. It's nasty teasing that we - not all teasing; nasty teasing you cut out.

I think it takes a long time, as you get older, to realize just how crazy the world is, just how ridiculous it all is.

I was very sad to hear of the death of Ronnie Barker, who was such a warm, friendly and encouraging presence to have when I started in television. He was also a great comic actor to learn from.

I don't miss London much. I find it crowded, vast and difficult to get around. Cabs are incredibly expensive.

I started to make harder jokes before anyone else did. And the producers would get anxious. They'd say, 'That's a little bit hard-edged, isn't it?' And I'd say, 'Let's just try it and see how the audience reacts. If they don't like it, let's cut it out.' And the audience roared with laughter, so I learned you could do this harder humor and people loved it.

I think there are so many activities going on, like mountaineering. You know, you would pay good money not to have to do that, and yet there are people racing out who want to spend their spare time clambering up rocks.

I was always a sports nut but I've lost interest now in whether one bunch of mercenaries in north London is going to beat another bunch of mercenaries from west London.
