I’ve learnt from experience that a painting isn’t finished when you put down your brush – that’s when it starts. The public reaction is what supplies meaning and value. Art comes alive in the arguments you have about it.

In the future, everybody will be anonymous for 15 minutes.

The human race is the most stupid and unfair kind of race. A lot of the runners don't even get decent sneakers or clean drinking water. Some runners are born with a massive head start, every possible help along the way and still the referees seem to be on their side. It's not surprising a lot of people have given up compeating altogether and gone to sit in the grandstand, eat junk and shout abuse. What the human race needs is a lot more streakers.

I figure there are enough self-opinionated assholes trying to get their ugly little faces in front of you as it is. You ask a lot of kids today what they want to be when they grow up, and they say, 'I want to be famous.' You ask them, 'For what reason?' and they don't know or care. I think Andy Warhol got it wrong - in the future, so many people are going to become famous that one day everybody will end up being anonymous for 15 minutes.

Stencils are good for two reasons; one - they're quick; two - they annoy idiots.

Keep your coins, I want change.

Graffiti is one of the few tools you have if you have almost nothing. And even if you don't come up with a picture to cure world poverty you can make someone smile while they're having a piss.
