During last Saturday’s taping of Saturday Night Live, the cast was spoofing PBS. But host Sam Rockwell apparently didn’t get the message that cursing isn’t allowed.

The scene took place in a science room opposite Cecily Strong and Mikey Day, who played obnoxious students. Apparently they were so annoying that it drove Sam to throw an F bomb. His mistake was bleeped out on the West Coast.

Props, I guess, to Cecily Strong and Mikey Day for rolling with Sam Rockwell’s f-bomb pic.twitter.com/ZcqrzoeG1U
