Party Trick: (Noun) A gag or trick performed to amuse people in a social setting.

Madonna's brother Christopher Ciccone says that his book My Sister Madonna was originally supposed to feature salacious tidbits which his lawyers made him edit out. Good thing his lawyers don't have any say in what he tells the media! Otherwise, we'd be deprived of this delightful story about Demi Moore:

He says, "There are certain stories that don't end the way that they end in the book. It's not really family stuff. It's more like - well there's a bit in the book about Demi Moore and I dancing on the bar. She's dancing up on me and humping me from behind.

The one part that's not in the book is that she was lactating at the time and she was squirting breast milk at my lesbian friends." "My friend Michelle called me the next morning and asked me, "How do I get breast milk out of my black dress?" and I said "How the f**k would I know? Call Demi.' It was hysterical. There are no pictures of it but it actually happened." (Source)

It's just a shame Ashton Kutcher wasn't around back in those days to jump and and scream: "AHHH!!! My wife just squirted you with her TITTY JUICE!!! Oh dude you are so TOTALLY PUNKED." Of course, if Kutcher had any say, they probably would have taken it a step further by sneaking chunks of frozen afterbirth into people's cocktails. And the "Bloody Rumer" would have been the hottest drink craze of the 80's! Who's hungry for lunch?
