People come up to me in supermarkets and demand humour. And the less amusing I am, the more they piss themselves. So I say, "I'm doing my shopping, mate, OK?" and the guy will be on the floor in hysterics. Quite odd. Eventually I do have to say something funny so I usually go for something pathetic like, "It's a nice place to shop but I wouldn't like to live here!" and they roar again. Wet themselves. I'm lucky though that I am not massively famous, I can get the Tube without much bother. Must be awful being the Beckhams.
