About George Carlin:
George Denis Patrick Carlin was an American stand-up comedian, social critic, actor, and author. Carlin was noted for his black comedy and his thoughts on politics, the English language, psychology, religion, and various taboo subjects. Carlin and his "Seven dirty words" comedy routine were central to the 1978 U.S. Supreme Court case F.C.C. v. Pacifica Foundation, in which a 5–4 decision affirmed the government's power to regulate indecent material on the public airwaves.
I think it's the duty of the comedian to find out where the line is drawn and cross it deliberately.
