INDIANAPOLIS – Before the freshly retired David Letterman drives off into the sunset, he's set for a trip at the Indianapolis 500.
Letterman's IndyCar race team paid tribute to the former "Late Show" host by putting a caricature of his face and #thanksdave on the car of driver Oriol Servia for Sunday's race.
Team members wore gray T-shirts with their own "Top Ten" list of reasons they love Letterman. Among them: Cries on the parade lap.
Letterman says of the tribute, "with everything that's happened, it's the highlight of my career. It's crazy it's the Indianapolis 500."
