LETTERMAN AND COLBERT SAY GOODBYE TO 'THE LATE SHOW' #DavidLetterman was one of #StephenColbert's final guests on #TheLateShow, as the franchise's two hosts go their revenge on CBS by throwing furniture off the roof of the Ed Sullivan theater. Letterman created "The Late Show" franchise in 1993 and hosted the late night show until 2015, passing off the reigns to Colbert. The final episode of "The Late Show" is set to air on Thursday, May 21.
