We seem to forget that the first group that tried to ban Carlin's performance was from the "right" side of the political spectrum.
Recording material for a new album, Class Clown, he debuted a monologue called "Seven Words You Can Never Say on Television." Rattled off to hearty laughter and applause, the words were: st, ps, fk, ct, c********r, m**********r, and t**s.
The bit was meant to highlight the absurdity of signaling a few words out of the roughly 400,000 in the English language that would somehow corrupt our souls by repeating them for public consumption, and Carlin effectively made his point with silly voices and simple logic.
But the funnyman knew he was treading in dangerous territory: He had been with Lenny Bruce a decade earlier when his mentor was arrested in Chicago for saying at least two of those forbidden words during a show.
Sure enough, Carlin met the same fate in Milwaukee a few months after debuting his "Seven Words." His arrest was eventually thrown out, but the bigger battle was just beginning.
