I gotta go with the classics. In no particular order...
- George Carlin
- Rodney Dangerfield
- Richard Pryor
- Bill Cosby
- Gallagher (the rest of his show, not the 5 minutes of sledgehammer and watermelon mess that he's known for)
The next generation after them...
- Richard Jeni
- Dennis Miller
- Tim Allen
And on a still younger note...
- Adam Ferrara
- Gabriel Iglesias
- Christopher Titus
