See, I disagree. Someone retelling their memory of some of his bits, or your nephew performing at his birthday party would be telling old George Carlin jokes. This was new material and was topical, which I think is cool. It's hard to know what George would really think about today's climate, but I can't imagine it would be too far off from the this.
Was it perfect? No. But if I know what it is going in, I can sit back and just enjoy it for what it is - entertainment.
The bit about AI Bill Cosby made me laugh the hardest. "You get all of the Cosby jokes with none of the Cosby rapes!"
