Richard Pryor and George Carlin downloads - where to start?

I am downloading some stuff, and wonder what albums of these two I should start with. They are both before my time and there are so many.

What do you consider their best, and what should I start downloadin

Don’t know any of their albums by name, but I think their earlier stuff was funniest. After the funny material ran out, they both just descended into using the F-word every other word. The Carlin “Hippy-Dippy Weatherman” was pretty funny.
