The wishbone tradition is said to date back millenniums, carried from one culture to another in a attempt to bring luck to those areas in life where they long for thro greater abundance through some mysterious source.
We are familiar with drying the unbroken wishbone from a chicken or turkey and allowing it to dry. The tips of the wishbone were then held by two prosperity-seekers, each with their own wish, and they both pull to break the wishbone in two. The person holding the larger portion of the wishbone was believed to be granted their wish. The more commonly known two-person breaking of a wishbone, is preceded by an ancient ritual that if two girls break the wishbone the one who gets the shorter piece will get married, the one receiving the longer piece will remain unmarried. These days some might see this as the opposite of our current day belief that the longer end is good luck, given the revolving door attitude of some marriages!
