"I'm celebrating because I'm in a huge (frickin') fight with Bristol Palin!" the Grammy-nominated performer announced exuberantly at The Fillmore Miami Beach at the Jackie Gleason Theater, drawing thunderous hoots and shouts from an audience several hundred strong.

Cho claimed on her blog recently that Bristol, her Dancing With the Stars rival, was forced onto the show by Sarah Palin.

She repeated this assertion at The Fillmore, adding, "I didn't dance a lot, so I had a lot of time to gossip (on the set)." Cho segued Dancinggate into a rant against Sarah and the former vice presidential candidate's politics: "She would be the worst (frickin') president ever," said Cho, who also then railed against conservatives in general, particularly those she says pepper the Atlanta area, where she's living while working on her "Drop Dead Diva" series for Lifetime.

In one passive-aggressive catfight she described with an anti-gay group who'd set up a booth at a local gym with "family values" magazines, she spoke of loading up their table with pro-gay literature every chance she got.

"If I made one gay kid feel good about himself, I (frickin') won," concluded Cho, a bisexual well-known for her advocacy for the LGBT community.

None of the politically tinged opening segment of Cho's act was particularly funny, but the crowd still loved it and loved her for it, having been pumped up by her tourmate John Roberts, who plays Jimmy's mom on NBC's Late Night with Jimmy Fallon. Roberts donned wig after wig to pound out outrageous character vignettes ranging from John Travolta to a drunk Jersey girl, all the while disco dancing and muttering, "So stupid ... so stupid" about his own antics with a giggle.

For her part, Cho mercilessly mocked her own mother, pulling her face into a caricature of Confused Elderly Asian. "Maybe it better if you just die," Cho imitated as Mama Cho, in response to 14-year-old Margaret's desire to become a comic.

In what’s become a trademark for her, Cho weaved anecdotes about her mom throughout the night, revealing that she was a mainstay in the DWTS audience, and mentioning that one time she accidentally sexted her. She spoke fondly of her grandfather, whose face was disfigured in a fire, as a sympathetic and accepting -- yet stoic -- figure. "The only time Koreans get emotional is when someone dies or shoplifts," Cho concluded.

She grew increasingly raunchy -- and more can't-catch-your-breath hilarious -- as the night went on. Also a singer who released an album called Cho Dependent this year, she treated the audience to a few ditties accompanied by guitar. ("I started playing guitar because I saw Madonna doing it, so how hard could it be?")

From sex to politics to racial tensions, no topic was off-limits.

"I love white people, but when there's a lot of white people together they start playing bagpipes," she said of her fear of steeplechase events. White folks look at Asians, Cho said, as if they're thinking, "Hey, you look like you do stir fry real good. And offer tech support."

She drew frequently on her experiences in the gay community. Pretending to be taken aback by Grindr, an iPhone app that lets gay men find other gay men near them, she exclaimed, "The closest thing we lesbians have is Animal Rescue!"

She likes men too, yet she wishes it were easier to hook up with them on Craigslist. "I'll send them pictures of myself, and they're like, 'Why are you sending pictures of Margaret Cho?'"

She chatted about the horrors of portapotties at outdoor festivals, about her dream of opening a combination strip club/assisted living center, and about talking to Cyndi Lauper after eating an entire medical-marijuana lollipop ("I have no idea what happened after that. ... I think it was on Fox News though”).

Getting a big response were tidbits from across news and pop culture, such as JetBlue employee Steven Slater, who became a folk hero after he cursed out a passenger, grabbed beer and slid down the jet's chute. "He's the Nelson Mandela of flight attendants," Cho pronounced.

Other zingers:

• On a man she pined for from afar for years, only to find he'd later bludgeoned his wife to death: "So, it's really good that we didn't hook up."

• On her fellow gays and lesbians: "We walk in a tight formation, 'cause we're used to being in a parade."

• On a man a relative wanted to set her up with: "’He not good looking, but he very tall, so he face far away!’"

• On Latisse, the prescription eyelash-growing drops she says she's addicted to: "Brooke Shields is my dealer."

• On things she thinks while smoking pot: "What would it be like to brush Chewbacca?"

But much of her act can't be repeated here, including the end result of her vocal chord-soothing olive oil therapy, her and tourmate Roberts' secret plans for the sound guys at the Bonnaroo festival, what she wants to do on her first day of living in a nursing home, and most of the lyrics to the songs she performed.

At the end, she brought Roberts back out and they both got into character as their mothers, singing a rap that would probably singe your own mother's eardrums.

Neither the title nor a single line can be repeated here.
