George Carlin is dead.

The Associated Press: George Carlin mourned as a counterculture hero

The label, "counterculture hero," may be fitting, but the world would be a better place if it didn't. The world needs more people like George Carlin.

The original seven words were, shit, piss, fuck, cunt, cocksucker, motherfucker, and tits.
...
I found three more words that had to be put on the list of words you could never say on television, and they were fart, turd and twat, those three.

Turd?

Times change. Thanks, George Carlin. More power to you.
