Here's a bit I thought was very funny on David Letterman's show back on NBC and I believe the date of it was November 20, 1991. It involved the Rockettes from Radio City Music Hall and the one who speaks is Dottie Belle — isn't that a great name for a Rockette? — who was part of the troupe from 1974 to 2000. In this article she wrote about it, she said they took 60 Rockettes to Dave's show but I only count 58 in the video.
