Although you might have to creep about at night and lie to your mum it’s actually one of the more honest art forms available. There is no elitism or hype, it exhibits on the best walls a town has to offer and nobody is put off by the price of admission.

You owe the companies nothing. You especially don't owe them any courtesy. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don't even start asking for theirs.

I don't know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.

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.

Speak softly, but carry a big can of paint.

If you feel dirty, insignificant or unloved, then rats are a good role model. They exist without permission, they have no respect for the hierarchy of society, and they have sex 50 times a day.

Modern art is a disaster area. Never in the field of human history has so much been used by so many to say so little.
