Believe it or not this works in parties of thirty or more almost every time. The larger the group the bigger the odds are in your favor.

Simply ask folks to announce their birthdays aloud and eventually someone will chime in and say, “That’s my birthday too!” It seems with three hundred and sixty-four days in a year you’d need several hundred people to make this work.

So not to embarrass some of the older crowd, I’ll tell them that it is not necessary to announce the year when naming their birth date aloud. Then I’ll ask of a mature woman, “Since it’s not nice to ask a lady her age… how much do you weigh?”
