If I do a picture, I want the audience to be the people I was just packed against on the subway or on the street, walking on Fourteenth Street. I don't want it to be some narrow public that I myself feel alienated from.

The client isn't quite satisfied and then the prostitute is always unsatisfied but is doing it just to make ends meet. And if you're doing fine art, if you're doing it for a gallery or a museum, it's so sterilized. It's such an antiseptic environment.

As I developed as an artist and studied art history, I noticed that all the great works were dealing with the human condition. [Art] had humor in it. It had sex in it. But it also had sorrow running through it.

When I was younger, when I was a teenager, the work was more satirical and funny and cartoony. And part of it was chops - if you have a more limited repertoire of stick figures and cartoon characters, they lend themselves more to humor than to tragedy.

The trick is not to look back, but keep on expressing where I'm at now. It's challenging to create something new, so it's crucial to dwell in the present moment.

Poster art was always my way of being involved in the conversation. So it wasn't just a one-way conversation with the police yelling at us or freaking us out. Street posters allowed you to have the last word.

Artists always live in the cracks anyway, whatever culture they're in. They're usually accustomed to not having much money, to kind of roughing it.
