When I was a young lad I read about a party game in an issue of Playboy I had somehow come into possession of.
In the game they described, one person or a mixed-sex couple would be covered with a sheet and told that in order to come out they must take off a specific pre-determined item, but they are not told what it is. Each article of clothing the victim(s) removed would be handed out from under the sheet, until they were finally able to come up with the item they were supposed to remove. At that point, their clothes would be returned to them.
Of course, the item they needed to remove to end the game was… the sheet.
The clothes-taking-off game sounds amusing, but at my party, I don’t seem to remember any nudity or states of clotheslessness.
I remembe that people were joking abut a camel while there were one or two people under the sheet, but I don’t actually know if the game was supposed to involve something camel-like… Gee, I must’ve been pretty hammered.
