Six Degrees of Kevin Bacon
My roommate has been reading The Origin of Wealth and came across a mention of Duncan Watts and Steve Strogatz who have done scholarly research on "Six Degrees of Kevin Bacon." Playing around with their database at The Oracle of Bacon has been extremely fun. Did you know that Atreyu from The Neverending Story was also in Troll and then your just one step away from Bacon himself?
I knew a guy in high school who wanted to get a tattoo so he could impress a girl. He wound up getting a tattoo of a heart with wings. A few years back he tried to out-gay himself on that one and he got a tattoo of the auryn, the crown thingy that Atreyu wears ... I don't talk to him much anymore.
