Greg Graffin: "If you ever get a hold of our first EP, a 7", there's a guy with a jacket - a leather jacket - in the audience and it says, 'You don't belong' on it. That's where we got the title from. And it was sort of the attitude all through the punk era; none of us felt like we belonged. But we certainly felt like we should belong, because we had something to say."
