Here is another "Mental Sorbet" that we could use to momentarily forget about those things that leave a bad taste in our mouths.
New Saturday Night Live cast member Jenny Slate drops an F-bomb in the middle of a live skit New Saturday Night Live cast member Jenny Slate. Her face is awesome once she realized her mistake.
The late Charles Rocket, surrounded by the mostly unknown cast (although young Eddie can be seen behind him) parodying the "Who Shot JR" sequence from the TV show "Dallas", that was one of the biggest pop culture items in late 1980, tells host Charlene Tilton (also on Dallas at the time) that "It has been the first time he has been shot in his life, and he'd like to know who the fuck did it". This originally aired live in the East Coast, edited for the West Coast airing later that night, but surely has to be the earliest instance of the profane word uttered on National TV.
