For anyone who doesn't know, George Carlin passed away on Sunday of heart failure, he was 71. If you don't know who he was then I really have no clue what rock you were hiding under. He did a lot of guest appearances on TV shows and did have a very short lived show of his own. The George Carlin Show, which ran for something like 12 episodes in 1994-95. What I remember him for most, sadly, is Rufus in Bill and Ted's Excellent Adventure and the sad movies that followed that travesty. More recently he was the voice of Fillmore in Cars and The Wizard in Happily N'Ever After.
Oh yeah and obviously he was a stand up comedian! Here's a clip of one of his routines. Warning! If you are in any way offended by crude language then don't listen to this. He was one foul mouthed little man!
