Golden Globe winner Sam Rockwell made a big splash while guest-hosting "SNL" this weekend — and he did it in a way that wasn't scripted!
The "Three Billboards Outside Ebbing, Missouri" actor was in character as an increasingly frustrated science teacher instructing idiotic students (Cecily Strong and Mikey Day) when he blurted out, "You can't be this f*cking stupid!"
Amazingly, none of the actors broke character.
NBC has not commented on the slip, which has happened on the show in the past, with different outcomes.
On a 1981 episode, cast member Charles Rocket (who died in 2005) asked who the "F" did it while in character as shooting victim J.R. Ewing of "Dallas," and Jenny Slate — in her first live appearance — used the word opposite Kristen Wiig in a sketch she had written. Both cast members were let go, in part due to their loose lips.
Guest hosts Samuel L. Jackson (2012) and Kristen Stewart (2017) uttered the word without much of an outcry.
This weekend's "SNL" was also noteworthy for the uncensored use of the word "sh*thole" in coverage of President Trump's controversial remarks slamming Africa and Haiti.
