***TRUE HISTORY***
When the Air Force first started, The commander gave them all a medallion or coin in a pouch to wear around their necks, one of the pilots was shot down and captured. He some how escaped and got to his allies, and they were about to shoot him and he presented his coin, so instead of giving him a bullet they gave him a bottle of wine.
now if you challenge someone, if they dont have theeir coin they owe you a drink, but if they do then you owe them a drink.
