Regis & Letterman: Man Kisses, Slut Talk & A Wrecked Vespa

Regis Philbin appeared on the "Late Show with David Letterman" on Thursday to discuss his television talk show career retirement. The final episode of "Live with Regis and Kelly" aired yesterday in front of a live audience filled with family members and famous faces.

During his visit with Letterman, the two discuss a photographed make-out session between the two TV hosts, Letterman calls Philbin "a slut" and Philbin gets his Vespa cherry popped.

Letterman gifts Philbin, 80, with a shiny new red Vespa and matching helmet as his retirement present. Philbin, a Vespa virgin, decides to take the "very safe" scooter for a ride outside the Ed Sullivan Theater in New York City. His ride is brief, mildly disastrous and very entertaining to watch. Check out the footage below in our Saturday video lunch.

Gawker cut together "The Best Four Minutes of Regis Philbin's Letterman Appearance," where you can view the kiss-and-tell plus other highlights of the droll duo.
