I'm in favor of an art that does something other than just sit on its ass in a museum.

The end of the '60s was a terrible time. I was in Los Angeles then, and I remember the night someone ran into the studio and told us about the Manson murders. Then suddenly something happened, the '60s disappeared. The '70s were completely different.

Everything I do is completely original-I made it up when I was a kid.

My work doesn't have the same rules as, say, Andy [Warhol]'s work. But it's gathered together for the simple reason that we all worked with the images and objects around us.

I am an immigrant in a sense. What happened was that my father was stationed in New York when my mother became pregnant, and she said, "I've got to go to Sweden so this child can be born there, because you don't have any idea where you're going to be transferred next."

The art world was very small and the people got together at parties. There was less commercialism.

I'm always careful to say that I changed everything I found.
