"Someone famous once said 'It takes two people to make a piece of art. One person to make the art and another person to stop them from destroying it.' Which is a more poetic than saying: 'It takes two people to make a piece of art. One person to make the art and another person to come round later from the council and sand-blast it off."

“Well I'm frustrated by many things but trying to get accepted by the art world isn't one of them. This seems difficult for some people to understand - you do not paint graffiti in the vain hope that one day some big fat tory will discover you and put your pictures on his wall. If you draw on walls in public then you are already operating on a higher level.”

“Nobody ever listened to me and I used to think that was their fault. Eventually I got to realise maybe it was the fact I was boring and paranoid that was the problem. But you find that people who know you rarely listen to a word you say, even though they'll happily take as gospel the word of a man they've never met if it's on a record or in a book. If you want to say something and have people listen then you have to wear a mask. If you want to be honest then you have to live a lie.”

“Become good at cheating and you never need to become good at anything else.”

“I think I was lucky to learn so young that there's no such thing as justice and there's nothing you can do about it. The more useful lesson I learnt was that there's no point in behaving yourself. You will probably be punished for something you never did anyway. People get it wrong all the time.”

“The craft is finding a decent drainpipe to get access to the site as much as it is in the art... Van Gogh used short, stumpy brush strokes to convey his insanity - I use short, thin ledges above mainline train tracks." — Evening Post, 2004”
