George Carlin is one of the most legendary stand-up comedians of all-time and probably the most consistent comedian to ever live. Carlin's stand-up philosophy and brutal honesty helped shaped an entire generation of comedians and his work has been reworked and regurgitated by even some of the best comedians of today. Carlin has a total of twenty comedy albums under his belt and sixteen televised comedy specials which is an insane amount of work for a single act to complete. Think about the next greatest stand-up comedian you could think of, Richard Pryor, Chris Rock, Chappelle... Not sure if they can hold a light to Carlin's flame.
Carlin does share a physical liking to English geologist, biologist, and naturalist, Charles Darwin, the man behind the theory of evolution. Darwin believed that through the theory of natural selection the weak are eventually bred out of a species leaving the best to manifest and thrive. Darwin's theory clashed with bible thumpers but yet he's known as one of the most respected and influential people in history.
