Six Degrees of Separation

You know when you hire a couple of DVD's and you find that there's a common actor, plot or location? It's spooky. Or you meet you kid's friend and find out he's the nephew of someone you went to school with? I watched a movie this afternoon that opened with loads of antique clocks ticking in someone's 'parlour' and it reminded me of someone I know who has an interest in timepieces and the six degrees theory kicked in. Years ago, my milkman was the estranged father of an old school friend - she never spoke of him but I spoke to him every day. I have a friend in NewZealand who's uncle served in the Hong Kong police at the same time as my Godfather - he doesn't know if they knew each other. I worked for a man who turned out to be the husband of a dear friend of my friend who lives in Melbourne the connection made only because he has an unusual surname. I have another friend who's family emigrated to Australia on the same ship that I did and I met her 25 years later. I'm yet to make a Pennsylvanian or Irish connection but it's really weird how you are separated from people by often much fewer than six degrees. *queue twilight zone music* Any stories of six degrees or less in your world?
