I still have a video from 1987 or 1986 of David Letterman when he was still on NBC. He interviews Cybil Sheperd while she's dressed in nothing but a towel.
The great part about the tape is the commercials in between. Growing up in Pittsburgh I see a commercial for I.C. (Iron City) Light (Hey! Gimme an I. C. Light..), Dannon Light 'n' Lively 6-pack, White Mountain Wine cooler, and Swatch watches.
