On February 20, 2009, NBC aired the last episode of "Late Night with Conan O'Brien". The show consisted of a compilation of previous "Late Night" clips and included a surprise appearance by former sidekick Andy Richter. Will Ferrell, John Mayer, and the White Stripes also appeared. O'Brien ended the episode by destroying the set with an axe, handing out the pieces of the set to the audience, and thanking a list of people who helped him get to that point in his career. Among those thanked were Lorne Michaels, David Letterman, Jay Leno, and O'Brien's wife and children.
