I remember Aniston in one of her first appearances on the Letterman show where she talked about doing a show at the Public. She dismissed her role - "I played 'the girlfriend'" - but she said it was a great experience and "it was great getting to meet Mr. Papp before he died."
Dave said "That's the time to meet him! After that, you're just sittin' around in the waiting room!" She laughed at that one.
