Co-stars Yeardley Smith and Hank Azaria appear to promote their Fox shows "The Simpsons" and "Herman's Head". A clip of the show is shown after their interview with guest host Chris Lemmon.
Lisa (Yeardley Smith) begins to laugh to herself and says that she is "thinking of a joke I saw on 'Herman's Head.'" Smith was also a cast member on "Herman's Head."
