George Carlin, who died this week at 88, was one of the most influential comedians in America, a man who took politics to new heights of vulgarity, and who created one of his own.
He also wrote an incredible memoir, The Great American Lie.
Here are five facts you may not know about him.
He was born in 1912 in New York City.
He started performing at the age of 14 in the small city of Syracuse.
He made his debut at the Guthrie Theatre, a theatre in Chicago, in 1929, and performed in the same show until the 1970s.
His most famous comedy routine was “The Last Sunday in July”.
It features Carlin playing a man he has been repeatedly abused by, and a woman he is having an affair with.
He tells the story of the night of the abuse, which begins with him drinking in the middle of the day, then he goes to a bar and drinks with his friend.
He performed a number of shows before his death, most notably the one with Louis CK in 2008.
He has said he is “not interested in the money”, but says that his “spiritual calling” is to be “a prophet of truth”.
