Man: You came all the way out from Manhattan for this?
Jerry: Yeah. Yeah, I did.
Man: So what do you do?
Jerry: [pats his head] I'm a comedian.
Man: Are you? Lemme ask you something. Where do you get your material?
Jerry: [still patting] I hear a voice.
Man: What kind of voice?
Jerry: A man's voice, but he speaks in German so I have to get a translator.
Man: How come you keep tapping your head.
Jerry: It's a nervous tic. I'm on L-Dopa.
