Graffiti is only dangerous in the mind of three types of people; politicians, advertising executives and graffiti writers.

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.

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.

Graffiti ultimately wins out over proper art because it becomes part of your city, it' s a tool; "I'll meet you in that pub, you know, the one opposite that wall with a picture of a monkey holding a chainsaw". I mean, how much more useful can a painting be than that?

The grumpier you are, the more assholes you meet.

I have a theory that you can make any sentence seem profound by writing the name of a dead philosopher at the end of it.

Art should comfort the disturbed and disturb the comfortable.
