"I don't know how much it changed my life. It creeps up on you really. You become used to it quickly, I think. I wasn't aware of it suddenly changing my life, although I had a bit more money to spend on rubbish. I bought a house, but the money was rubbish because I was a BBC newcomer, though nobody's money was very good, except probably Robert Hardy's. I remember after the third series I bought a car, which was a Renault 18. I thought it was pretty flash, and I went to this garage to fill up with petrol, and the guy said, 'Aren't you that bloke off the vet series?' I said yes I was, and he said, 'Why are you driving that piece of shit?'"
