George Carlin
George Carlin is one of my heros, I don't agree with him in many things, and his understanding of economics is a bit lacking, but he is an absolute genius, and I love how he trounces political correctness and other generally accepted nonsense.
Here are two great shows by him:
His rant on religion is as close to perfection as a rant can be.
And his essay about children is beautiful.
