Pinette and Titus are great. Two different styles, though.
I guess if you can get into “out of left field” humor, Dmitri Martin, Steven Wright, and Mitch Hedberg (who work mostly clean) are some faves of mine.
Lewis Black is the modern George Carlin. I will die on THAT hill.
Carlin is the GOAT, no doubt. I’m a big fan of Anthony Jezelnik but I can’t really remember how close to “clean” he is. I don’t necessarily remember a lot of sex talk. He does talk about some f’d up stuff but he is the king of delivery.
