However, Brooklynite Buddy Hackett and Queens- born Don Rickles soon developed a style of humor that offended audiences, both thematically – with racial and religious jokes – and literally, testing the crowd with ad-libbed dialogue and cursing. The New York comedic titans of the 60s, Lenny Bruce, Mort Sahl and Shelley Berman, pushed the envelope even further with coarse social commentary that, for the first time, sought to shock people into laughter.

Self-deprecation, ethnic jokes, and mocking the out-of-the-ordinary are the now standard shtick for most politically incorrect routines. Witness the gags on display during one night at Gotham Comedy Club:

"How do you circumcise a red neck?"
"You kick his sister in the chin."

"The only good thing about gambling at an Indian casino is that, if you lose, you feel like you’re helping. You’d be like, "Fuck, I lost $200. But it’s okay; let the Indians have it."

-- Mark Maron

"What do you call a Haitian on roller skates?"
"Roll-AIDS."

-- A joke popular in the 80s when Haitians were accused of bringing in AIDS, Wil Sylvince says
