I probably have the geekiest story behind my name.  It is a trow back between Star Wars and a Wing Commander video game.  In Star Wars there is the classic line, "Laugh it up fuzball".  Now my family used to call me the wookie because I am tall and lean, and used to be a lot grouchier when I was younger.  I changed things over to Furball because of Wing Commander Prophecy, because while in a Dogfight your fellow pilots would always say, "We have ourselves a furball."  So there you have it, the explantion of my geeky name.
