Tina Fey stripped down to her Spanx and literally gave Letterman the dress off her back. Bill Murray, who had been Letterman's first guest on his former NBC show, was also his last guest on CBS.

Letterman didn't have time to interview the countless celebrities he'd undoutbedly influenced during his storied career, so they're taking to social media to express their gratitude and admiration for the host.
