How many degrees of separation are you from someone famous or well known? Someone I know's adviser was a well known scientist who collaborated with Einstein. Another one of his students is also famous and worked on the Manhattan project and knew Teller and Oppenheimer. My former co-worker was an a few semi-well known punk bands and has hung out with Dave Grohl and Josh Homme. My other friend used to be friends with surfer Kelly Slater when they were growing up in Florida. My adviser's relative was FDR's personal physician and was present when he died.
