I give away thousands of paintings for free.

Policemen and security guards wear hats with a peak that comes down low over their eyes. Apparently this is for psychological reasons. Eyebrows are very expressive and you appear a lot more authoritative if you keep them covered up. The advantage of this is that it makes a lot harder for cops to see anything more than six foot off the ground. Which is why painting rooftops and bridges is so easy.

I think its pretty clear that film is the pre-eminent art form of our age. If Michaelangelo or Leonardo Da Vinci were alive today they’d be making Avatar, not painting a chapel. Film is incredibly democratic and accessible, it’s probably the best option if you actually want to change the world, not just re-decorate it.

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'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 just wanna make the world a better-looking place. If you don't like it, you can paint over it!

My lawyer's opinion is that the cops might not actually be able to charge me with criminal damage any more - because theoretically my graffiti actually increases the value of property rather than decreasing it. That's his theory, but then my lawyer also believes wearing novelty cartoon ties is a good look.
