Crown David Letterman the king of shade.

Letterman posted a video and a quip this week, seemingly in response to news that CBS would be ending “The Late Show with Stephen Colbert” in May 2026.

Letterman shared a montage of the many times he had roasted his own network over the years, when he was still working for CBS. Colbert succeeded Letterman as host of “The Late Show” in 2014, following Letterman’s 22-year run.

“You can’t spell CBS without BS,” the caption on the video reads.

The two men have been friends for years and have been guests on each other’s shows.
