From Wikipedia: "SixDegrees of Kevin Bacon or "Bacon's Law" is a parlour game based on the "six degrees of separation" concept, which posits that any two people on Earth are six or fewer acquaintance links apart. Movie buffs challenge each other to find the shortest path between an arbitrary actor and prolific actor Kevin Bacon."

The game:
