During the taping of his show on April 3, 2014, Letterman announced that he had informed CBS president Leslie Moonves that he would retire from hosting Late Show by May 20, 2015. Later in his retirement Letterman occasionally stated, in jest, that he had been fired. It was announced soon after that comedian and political satirist Stephen Colbert would succeed Letterman. Letterman's last episode 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.
