Watch David Lettermans Final Goodbye
For the last time, David Letterman signed off from his late-night show on Wednesday night. Light on the jokes, but heavy on the graciousness, the Late Night host thanked his entire staff  including crew, writers and the band  for all they had done for the show. "These people collectively," he said, "deserve more credit for this show than I ever will.", Yet, in the middle of Letterman's good-bye, bandleader Paul Shaffer summed up everyone else's thoughts, saying, "Thank you so much Dave, you've changed our lives.", Watch the full signoff here.
