Should be fun.....David Letterman will be on with Stephen Colbert Monday night.

Though he departed CBS' The Late Show back in 2015, fan-favorite talk show host and comedian David Letterman will return to the show next week, just on a different side of the desk. The Late Show With Stephen Colbert confirmed that David Letterman will appear on the series in an announcement posted to social media, revealing he'll appear on the series' new episode airing Monday, November 20th. In the video Colbert revealed: "On Monday, I am so happy to say, I will be joined, right there, in that chair, by a man who is no stranger to the Ed Sullivan theater; though I know for a fact he has not been here in eight and a half years because my guest will be Mr. David Letterman. Boom!"
