Bus stops are far more interesting and useful places to have art than in museums. Graffiti has more chance of meaning something or changing stuff than anything indoors. Graffiti has been used to start revolutions, stop wars, and generally is the voice of people who aren't listened to. Graffiti is one of those 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 somebody smile while they're having a piss.

I'd been painting rats for three years before someone said 'that's clever it's an anagram of art' and I had to pretend I'd known that all along.

I wouldnt want to be remembered as the guy who contaminated a perfectly legitimate form of protest art with money and celebrities.

People who enjoy waving flags don't deserve to have one.

It's impossible to predict which paintings will last and which won't. In New Orleans I painted on a dilapidated shop in a street littered with abandoned cars and rotting mattresses, then two hours later the piece was gone. It turned out I'd picked the side of a crack house and the proprietor didn't like the attention.

People either love me or they hate me, or they don't really care.
