I really like the spin the bottle idea!
What about this one?
Each man is blindfolded and then five women take turns kissing him. He has to see if he can guess which woman is his "significant other."
And for a prize, if the man guesses right, he gets to remove an article of clothing from the woman of his choice, and if he guesses wrong, he has to remove a piece of his own clothing. Everybody wins!
hee hee!
