Honey: Sir, I've got a reporter on the line. He wants to know why you only have one name. Duke: Tell him I came by it honestly...on my first day of school, my mother dropped me off with a tag that just said "Duke" pinned to my shirt. For some reason, she never came back to pick me up. Honey: What? Duke: So that's how I grew up without a last name. Honey: That's so...so sad. Duke: Yeah. Fortunately, you didn't need one in the porn industry.
