There are certain places where you'd assume there aren't any rules, and one of those places was Hugh Hefner's Playboy mansion.
A huge house filled with scantily clad women walking round, which has high security surrounding it so people have no idea what goes on inside... yep, seems like a place where anything goes.
However, according to Piers Morgan, who was lucky enough to be personally invited there, there was one golden rule laid down by the late Hefner - which he broke.
Writing in his column for the Daily Mail following the Playboy founder's death, he recalled meeting him 10 years ago.
He'd been invited to the 'legendary' Midsummer Night's Dream summer party, which he thought would be suitable to take his wife (his fiancée at the time) to.
Now I can't confess to know exactly what happens at a party at the mansion, and I'm willing to bet you can't either, but I'll happily lump a large sum of money on it not being a bring-your-fiancée kind of event.
Piers says that his former America's Got Talent co-judge, David Hasselhoff, was baffled by the revelation.
"Man, don't you know the golden rule? Never take sand to the beach," he said, according to Piers.
The Good Morning Britain presenter went on to detail the party, writing: "We were greeted by the most eye-popping spectacle: hundreds of mostly semi-naked and completely naked women with various body parts painted, swarming around inside a giant, fabulously decadent marquee.
"In the centre lay the infamous Grotto, surrounded by a vast artificial lake, where some guests were already frolicking in the cave-infested water.
"As I soaked in this extraordinary scene, Paris Hilton arrived wearing nothing but Agent Provocateur lingerie and very high heels.
"I followed her into Hefner's private Bedouin tent to meet our host.
"He was 82 at the time, wearing a toga, lying on a large bed with a dozen or so stunning Playmates, and sporting an understandably gigantic smirk."
He went on to describe how the two of them had a fleeting exchange, before the party dragged on and his missus was consistently chirpsed by a movie producer, and Morgan had to keep his hands to himself while two twins got cozy with him.
Others didn't have the same decorum and will power, something which led him to label it the "nearest thing to a Caligula-style Roman orgy I have ever experienced."
Hefner died at the mansion last week at the age of 91. Announcing his death, Playboy Enterprises said: "Hugh M. Hefner, the American icon who in 1953 introduced the world to Playboy magazine and built the company into one of the most recognisable American global brands in history, peacefully passed away today from natural causes at his home, The Playboy Mansion, surrounded by loved ones. He was 91 years old."
In 2011 he said to The Hollywood Reporter: "Could I be in a better place and happier than I am today? I don't think so. In my wildest dreams, I could not have imagined a sweeter life."
