If you missed Saturday Night Live last night (1/13), you missed host Sam Rockwell dropping an accidental F-bomb.

During a sketch in which Rockwell portrayed Mr. Science, the actor is getting frustrated with the idiocy of his students. So frustrated, in fact, that Mr. Science used a word you most certainly can’t say on national television.

In the video above, you see the edited version of the Mr. Science sketch, courtesy of the Saturday Night Live YouTube channel. Below, you’ll see the video as it aired on TV, complete with Rockwell’s unedited F-bomb:

There’s no word yet on whether or not Saturday Night Live will face any sort of repercussions from the unedited F-bomb.
