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.

The veteran comedian, 78, shared a video montage of him roasting the TV network during his decades-long career of hosting "The Late Show" from 1993 to 2015.

Stephen Colbert gained a little help from his friends and late-night rivals on Monday, his first night back on-air since announcing that CBS is ending the legendary show.
