How to evaluate george carlin?

Being a sharp and humorous gadfly, making people used to everything, without the pain of being thoroughly remoulded, may be the most remarkable achievement of george carlin (1937~2008). He is not the most famous actor and writer in America, but he is the most controversial and incisive comedian in the history of talk shows.

American political talk shows (like China's stand-up comedy, Sanda storytelling and Shanghai storytelling) which emerged in 1960s are no longer satisfied with being funny, but criticize current politics with black humor and cold jokes. 1972, 35-year-old george carlin was fined and arrested for swearing "seven words never to be said on TV", and the lawsuit went to the US Supreme Court. In george carlin's dictionary, there is no dirty language at all, only dirty attempts and dirty thoughts.
