You Thought The Playboy Mansion Was Bad? 20 Jaw-Dropping Secrets From Inside Nevada's Raunchy Brothel 'The Bunny Ranch' EXPOSED

From group sex to strict curfew rules, Hugh Hefner's ex Holly Madison told all about her experience at the Playboy Mansion in her new memoir. But Dennis Hof, the owner of legal Nevada brothel the Moonlite Bunny Ranch, makes Hefner's house look like a nunnery! The self-proclaimed "pimp" dishes about his dirty deeds— and those of his girls and celebrity guests— in his new tell-all, The Art of the Pimp: One Man's Search for Love, Sex And Money.

Long before Hof purchased the ranch in 1993, he was a frequent guest— along with late comedian Andy Kaufman. The funnyman loved watching the girls wrestle, and had a hard time picking and choosing his lovers. "I like all of you, and I want to party with all of you. And if I have to come back morning, noon and night for the next two weeks well, that's exactly what I'll do," Kaufman said, according to Hof.

One of the first guests to the Bunny Ranch was the notorious John Wayne Bobbitt, who made headlines when his wife cut off his penis in his sleep. Though Hof calls him a "nice guy," he "ended up running off" with one of his girls!

When working girls arrive at the Bunny Ranch, Hof hands them a copy of the Bunny Bible, which teaches them proper bedroom etiquette. "There will be no T-shirts, Levis, or Levi Shorts worn by the ladies while they are working," the 100-page book reads.

Hof's best friend of many years is infamous porn star Ron Jeremy. One time, Jeremy pranked him by hiding in Hof's closet during the ranch owner's romp with a married swinger. When it was over, Jeremy came out clapping.

Another member of Hof's high-powered entourage? Hustler CEO Larry Flynt, who invited Hof and Jeremy to his wild 1998 wedding. The People vs. Larry Flynt star Courtney Love flirted with Jeremy, and called herself a "huge fan."

Not all of Hof's clients have happy endings at the ranch. When an elderly man won Howard Stern's contest for the best grandpa to get a free romp at the ranch, he died moments before his appointment with blonde babe Caressa Kisses.

Despite admitted cattiness between his female sex workers, Hof calls his ranch a "family." Every Thursday, his assistant Suzette holds a tea party for employees to air their grievances and work out any problems.

Some of the clients are quite unusual, Hof says. "We had a guy who came in to have a pillow fight with one of our bunnies, naked, but he wasn't interested in sex," he writes. "Another client enjoyed being diapered. And still another showed up as a clown with the face paint and the wig and the bulbous red nose and everything."

Girls gone really wild: Hof insists that his girls get it on in between clients— with each other! "Some of them happen to love sex," he explains. "That's not a myth."

Hof made no secret of his enemies in the memoir. He can't stand journalist Diane Sawyer, who interviewed Hof for a story on the Bunny Ranch in 2008. "If you didn't give her the answer she wanted, the answer that, in her opinion, made for good television, she'd look at you as if you were a lower life-form," he claims. "She was uppity as hell. She was bossy and rude and acted like f*cking royalty. Everybody at the ranch hated her."

When conservative political commentator Bill O'Reilly called prostitution a "lazy business," Hof snapped back. "O'Reilly, try to have sex with guys like you every day and then come back and tell me how lazy it is!" he claims he told him.

Hof swears one of his girls was "roughed up" only one time, when Motley Crue singer Vince Neil came to the ranch. The rocker was arrested and pleaded no contest to a misdemeanor battery charge.

Another odd client: a food-fighting enthusiast. "We had a guy come in once and pay ten thousand dollars to have a food fight with three of our girls," Hof writes. "They were throwing Twinkies and Ring Dings at each other, and the guy was giggling like a little girl."

Hof had a fling with notorious madam Heidi Fleiss. "When he's done with me, I don't know whether to ask him to marry me or to call nine-one-one," she told Howard Stern in an interview.

Hof once bailed Liberace's lover Scott Thorson, played by Matt Damon in Behind the Candelabra, out of jail and housed him at the ranch.

When Hof busted his knee, his good friend Tucker Carlson, a Fox News reporter, gave him a cane "made entirely out of a bull's penis," he says.

Hof says he's had 4,000 lovers, but in his will, he left half a million dollars to his dog, Domino.
