9. Louis CK
A former writer for "Late Night With Conan O'Brien" and "The Chris Rock Show," CK's stand-up comedy focuses on the darker sides of sex, family and society. In this way he's reminiscent of Bruce, whose comedy sought out the darker side in almost any issue -- and often went way over the line separating dark from pitch black. Plus, one would never suspect from CK's fringe of unruly red hair and goatee that he's the crackpot behind "Pootie Tang." For a taste of the shifty ferocity of CK's humor, listen as he talks about how easy it is for people to make fun of "white trash" -- "Everybody laughs at them. Do you know why everybody laughs at them? Because they're poor, that's why. What's funny about them is that they're starving to death" -- and hear the audience howling with laughter. Are they laughing at the sheer meanness of his humor? Or is he slyly turning the audience into the very people he's really making fun of? (For a show schedule and humor tracks, click here.)
8. Chris Rock
Bruce didn't shy away from race relations; several of his most plangent bits, including "How to Relax Your Colored Friends at Parties," assailed white liberal racial guilt. Years later, Chris Rock would call to mind Bruce's race talk with this riff: "There ain't a white man in this room that would change places with me! And I'm rich! That's how good it is to be white. There's a one-legged busboy in here right now saying, 'I don't want to change. I'm gonna ride this white thing out, see where it takes me.'" (Rock's fourth HBO special, is out now on DVD.)
7. Eddie Izzard
In 1999, Izzard -- best known as the manic stand-up behind the shows "Dress to Kill" and "Glorious" -- played Bruce in a revival of Julian Barry's 1970 play "Lenny" in London. Reviewers praised Izzard in the role -- particularly for undercutting his own lighter spirits and injecting the role with the darkness and desperation Bruce himself brought to the stage. While Izzard's own jokes are far more innocuous than Bruce's (for a sample, go here to listen to his riff on "chickens"), their coming out of the mouth of a burly transvestite gives them a bit more zing.

6. Sacha Baron Cohen
On HBO's "Da Ali G Show," British comedian Cohen combines Lenny Bruce's willingness to deliver discomfort with Andy Kaufman's devilish persona-swapping. As Ali G, a clueless British rapper, or as Borat Sagdiyev, Kazakh journalist, Cohen interviews unwitting subjects like Buzz Aldrin, Jim Baker and Boutros Boutros-Ghali, forcing them into rhetorical corners by force of cluelessness. In doing so Cohen's not afraid to make himself look bad and his targets look worse: Witness the wince-inducing recent episode in which Borat got the patrons of a Tucson, Ariz., bar to enthusiastically sing along with him: "Throw the Jew down the well/ So my country can be free/ You must grab him by the horns/ And then we have a big party," which sparked an investigation by the British FCC and raised the ire of the ADL against Cohen (who happens to be Jewish). Lenny Bruce -- who noted that not only did Jews kill Christ but "we'll kill Him again when He comes back" -- would surely have approved. (HBO is airing reruns of the recent season of "Da Ali G Show" at various times; check schedules, or HBO's Ali G home page.)
