David Letterman's Final Episode of Late Show

David Letterman's last episode of Late Show aired on May 20, 2015, and opened with a presidential sendoff featuring four of the five living American presidents, George H. W. Bush, Bill Clinton, George W. Bush, and Barack Obama, each mimicking the late president Gerald Ford's statement 'Our long national nightmare is over.' It also featured cameos from The Simpsons and Wheel of Fortune (the latter with a puzzle saying 'Good riddance to David Letterman'), a Top Ten List of 'things I wish I could have said to David Letterman' performed by regular guests including Alec Baldwin, Barbara Walters, Steve Martin, Jerry Seinfeld, Jim Carrey, Chris Rock, Julia Louis-Dreyfus, Peyton Manning, Tina Fey, and Bill Murray, and closed with a montage of scenes from both his CBS and NBC series set to a live performance of 'Everlong' by Foo Fighters. The final episode of Late Show with David Letterman was watched by 13.76 million viewers in the United States with an audience share of 9.3/24, earning the show its highest ratings since following the 1994 Winter Olympics on February 25, 1994, and the show's highest demo numbers (4.1 in adults 25–54 and 3.1 in adults 18–49) since Oprah Winfrey's first Late Show appearance following the ending of her feud with Letterman on December 1, 2005. Bill Murray, who had been his first guest on Late Night, was his final guest on Late Show. In a rarity for a late-night show, it was also the highest-rated program on network television that night, beating out all prime-time shows. In total, Letterman hosted 6,080 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late-night talk show host in U.S. television history.
