Andrew: One morning recently [on GMTV] we had Gordon Brown, Miss Piggy and Heather Mills in the studio. You can't beat that for someone like me who thrives on thrills.
Andrew: I played in the Korean Open and Dunlop Masters and won £30,000. When I got home, I went straight to buy a brand new TVR sports car that was shaped like a phallus. What an idiot. I should have stuck the money in the bank and then got practising because I was playing particularly well at the time. Instead I just mucked about.
Andrew: If I'm going to do something strenuous, it's got to be before midday or after 6pm because I get a bit weary in the afternoons. But I can proudly say that I still play squash for Surrey and can still get the better of Peter Fleming on a tennis court.
Andrew: I left home to go to a minor college in Florida and lived in a trailer park where I didn't know a soul. That was character-building.
Andrew: I was lucky, because things can be difficult if you don't come from a wealthy background. Let's face it, tennis is not an urban youth sport. My local courts on Clapham Common in London cost £5 an hour to hire, so that's not exactly helping us to unearth champions. I loved the sport, got some breaks, benefited from help from my parents and elder brother David and put in plenty of effort.

Andrew: In my role with GMTV, I have to do things such as interview parents whose children have been murdered so I'm not going to worry about working with Mac. I guess the first few times I might have watched my p's and q's. I told him so last year, which made him smile.
