If you want someone to be ignored then build a life-size bronze statue of them and stick it in the middle of town. It doesn't matter how great you were, it'll always take an unfunny drunk with climbing skills to make people notice you.

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.

When you go to an art gallery you are simply a tourist looking at the trophy cabinet of a few millionaires.

People seem to think if they dress like a revolutionary they don`t actually have to behave like one.

Bus stops are far more interesting and useful places to have art than in museums.

If you don't own a train company then you go and paint on one instead... it all comes from that thing at school when you had to have name tags in the back of something... that makes it belong to you. You can own half the city by scribbling your name over it.

The art world is the biggest joke going. It's a rest home for the overprivileged, the pretentious, and the weak. And modern art is a disgrace - never have so many people used so much stuff and taken so long to say so little.
