Sorry that you did not get longer by hanging from a tree. Did you ever call Won Hung Lo as recommended by Dan? Won can do wonders on the wanger. Won usually guarantees a 14 incher after 2 months on his FDA witnessed "Hung Longer" fitness machine.
Oh, by the way, did the hair come from your friend's 3rd leg? Quintiles/Innovex have caught on to the 3rd leg trick! 3rd leg hair does not count.
