Late Show with David Letterman

In honor of the recent Sotheby's Auction that featured items once owned by John F. Kennedy, Biff comes stage on Jackie O's (alleged) riding lawnmower; in a pre-taped segment, Dave interviews CBS job applicants, during which he pressures college sophomore Todd Stevens to sing; Nathan Lane appears to show Todd how it's done; Dave leaves the show to have some coffee with a guy named Kenny.
