David's only film role is in the "Birthday Party" scene outside of Divine's trailer. He was the "singing anus". If you haven't seen the film you'll just have to watch it to see what I'm referring to, because I'm not going into detail lol. He's uncredited in the film. He chose to remain anonymous until both of his parents had died, at which point he'd go to screenings of the film and let people know who he was.
