BONG #7: "Six Degrees of Kevin Bacon"

"Six Degrees of Kevin Bacon 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.

Google has implemented this in its index and now you can find any actor's bacon number by googling "Bacon Number" + Actor's Name."
