George Carlin
1937 - 2008
George Carlin is best known for his anti-establishment humor, which includes bits like the seven dirty words you can't say on TV. Those who were kids in the early '90s might remember him as Mr. Conductor on Shining Time Station. He passed on Sunday from heart falure.
If you've never seen any of his work, look him up on Youtube or something.
I really need to put something other than death notices up here... So depressing.
