Comedy legend and sometime film star George Carlin passed away on Sunday due to heart failure at the age of 71. He was widely recognised as part of the"holy trinity" of comedians along with the late duo of Lenny Bruce and Richard Pryor. Carlin has had a long, storied career being the very first host of Saturday Night Live in 1975 and in 1978 was central to a case in the US Supreme Court concerning the government's right to regulate Carlin's, and other comedians, material on public airwaves. This arose due to Carlin's profanity laced (but hilarious) "Seven Words You Can Never Say On Television" performance. On the big screen he appeared as the voice of Fillmore in Pixar's "Cars" but will probably be best remembered by casual filmgoers as Bill and Ted's time travelling guru in "Excellent Adventure" and "Bogus Journey", however it is his vast back catalogue of comedy albums and HBO specials that will prove to be his enduring legacy. "Death is caused by swallowing small amounts of saliva over a long period of time." - George Carlin.
