Ever since 1965, when theatre critic/known sado-masochist Kenneth Tynan uttered the word “f**k” on “BBC-3,” one of George Carlin’s seven words you can’t say on TV has been, well, said on TV. It’s an easy word to overuse, and it’s only used effectively in two situations: 1) in an unexpected live moment, and 2) by skilled professionals. My current favorite cuss artist is Susie Greene on “Curb Your Enthusiasm,” which returns to HBO this Sunday for its eighth and possibly final season. Played by Susie Essman, Greene has unleashed numerous toxic tirades at her “fat f**k” husband, Jeff, and his “four-eyed f**k” client, Larry David, since the show began in 2000. In honor of Susie, and for all those who don’t mind dropping an F-bomb (I’m sorry for using that phrase, I really am) every so often — or constantly if you’re on one BBC comedy — here are ten great moments of the F-word on TV.
