David Letterman's final "Late Show" included an all-star group of guests like Jim Carrey, Jerry Seinfeld, Chris Rock, Tina Fey, and more.

The show started with video of the late President Gerald Ford saying, quote, "My fellow Americans, our long, national nightmare is over."   Then all the living former presidents said it, ending with President Obama.

David Letterman thanked his staff, Paul and the CBS Orchestra and his family in his final goodbye.
