There is a video of Ricky Gervais, Chris Rock, Jerry Seinfeld and Louis CK talking about comedy and their different approaches. This was before we knew about Louis CK but it was enlightening on how different the approaches are and I appreciated the difference between CK and Seinfeld. Seinfeld basically does the same act every year and changes maybe 20% at most. CK does an entirely new act each time. I did respect his decision to rewrite his whole performance each time he changes it.

Unfortunately things are where we are at now but I think someone said prior and Carlin would do the same thing and they are some of the greats in comedy
