Six Degrees of Kevin Bacon posits that every movie actor can be connected to Kevin Bacon in 6 movies or less. The Game is played where one player thinks of an actor or actress. The other player makes the connections back to Kevin Bacon. Simple, yes, but oddly compelling. An example:
'Q:' tom cruise
'A:'
kevin bacon
If you're not good at coming up with the answers, you can play this game at http://www.cs.virginia.edu/oracle/ which reports
The Oracle says: Humphrey Bogart has a Bacon number of 2.
See?! The Oracle wins! He gets a point for a more elegant solution. Unfortunately, the Oracle is probably some sort of high-powered computer database. It's better when you're playing with drunken idiots. Had the Oracle actually been a drunken idiot, he would be considered a very good player.
This is my 6DoKB:
According to TheTippingPoint, KevinBacon is not the best-connected actor in movies. That title goes to RodSteiger.
