George Denis Patrick Carlin (May 12, 1937 – June 22, 2008) was an American 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 by the justices affirmed the government's power to regulate indecent material on the public airwaves.

He is widely regarded as one of the most important and influential stand-up comedians of all time: one newspaper called Carlin "the dean of counterculture comedians." In 2004, Carlin was placed second on the Comedy Central list of the 100 greatest stand-up comedians, ahead of Lenny Bruce and behind Richard Pryor. The first of his 14 stand-up comedy specials for HBO was filmed in 1977. From the late 1980s, Carlin's routines focused on sociocultural criticism of modern American society. He often commented on contemporary political issues in the United States and satirized the excesses of American culture. He was a frequent performer and guest host on The Tonight Show during the three-decade Johnny Carson era, and hosted the first episode of Saturday Night Live. His final HBO special, It's Bad for Ya, was filmed less than four months before his death. In 2008, he was posthumously awarded the Mark Twain Prize for American Humor.
