The great thing about Glasgow is that if there's a nuclear attack it'll look exactly the same afterwards.

I don't understand art-speak. My pictures are big doodles. I'm amazed what people come up with when they look at them. There's one of a figure with two heads that somebody thought must be a comment on the state of matrimony. None of it is a comment on anything.

I think comedy is difficult, and I'm amazed so many people want to do it. I'll be buying jeans and somebody will say, "I'm a comedian" - the guy selling you the jeans. The desire to be a comedian is weird. I found it weird myself to want to be one; I was a schoolboy when I wanted to be one but I didn't know how to do it. That was 50 years ago, so times have changed greatly. There seems to be a long line of people desperate to do it and most of them are quite good.
