Colbert jokes Iran war may outlast Late Show’s final episode

Stephen Colbert turned his Wednesday monologue into a grimly timed bit of comic triage, saying he was “beginning to think this war might not be over before Memorial Day.” The line landed as he boxed up his Iran War jokes and sent them to Jimmy Kimmel, a joke that treated the conflict as material that might outlast The Late Show itself.

The timing sharpened the joke. CBS has already set The Late Show with Stephen Colbert to end on Thursday, May 21, 2026, and Memorial Day falls on Monday, May 25, 2026. That leaves only a few days between Colbert’s final episode and a holiday that, in his framing, might arrive before the war he was mocking had lost its news value.

The handoff also underscored how late-night comedy has become part of the public conversation around U.S.-Iran tensions. Colbert and Kimmel had both taken aim at Donald Trump’s rhetoric about the conflict in earlier April 2026 monologues, using satire to process a foreign-policy crisis that was moving quickly and carrying obvious stakes far beyond studio applause.

Kimmel has been a natural recipient for the material. The two hosts have appeared on each other’s shows, and Kimmel publicly defended Colbert after CBS announced The Late Show cancellation. That bond gave the joke an edge of real fraternity, as if one veteran host was passing along a live wire to another just as CBS prepares to shut down the franchise entirely.

The bigger story is not the joke itself, but what it says about the role of late-night television when war news dominates the cycle. Colbert’s line linked the end of his own show to the uncertain pace of the conflict, suggesting that comedy is now forced to track the calendar of geopolitics as closely as the network schedule.
