Read full description

Back in the 15th Century, two families were involved in a bitter dispute when the feud came to a head. One family sought refuge in a cathedral, while the other family sought to make peace by requesting that the first family come out and shake hands. But they refused, fearing they would be attacked. As a gesture of goodwill, a hole was cut in the door of the cathedral so the head of the family seeking peace could place his arm through the hole in the door to prove his attempt at reconciliation was honorable. Thus the phrase “Chance Your Arm” was coined – when the head of the family reached through the hole in the door, risking that his arm might be lopped off instead of his hand being shaken. He chanced his arm in order for the two families to settle their dispute and make peace. Thus is born Chance Your Arm: a fun and easy way to challenge your friends, family, coworkers, teammates, classmates, golf buddies, workout partners, whomever – to keep track of the winners and losers, and to know the score. Chance Your Arm… go ahead!
