Adam Sandler, Anderson Cooper, Jon Stewart, Jimmy Fallon, Seth Meyers, John Oliver and Andy Cohen were among those who made surprise appearances on Monday's episode after CBS announced that the late-night show would be ending in May 2026.

John Oliver, Jon Stewart, Jimmy Fallon, Seth Meyers and more had cameos during the July 21 episode of "The Late Show With Stephen Colbert."

The late-night host acknowledged that "a lot of people out there are bummed" about the show ending next May, so he tapped a few famous friends to cheer everyone up.

Stephen Colbert announced "The Late Show" was cancelled three nights after revealing his summer mustache on air. Coincidence?

Fox News host Greg Gutfeld is the ratings king of late night with 3.1 million average viewers, despite what Stephen Colbert may be telling his audience.

CBS could not figure out a path to profitability in an entertainment world increasingly dominated by streaming.
