Funny Bone

Just as I was about to type this I hit my funny bone. Hence the title of my post. I still haven't thought of a legitament reason for this bone to be called this. It isn't funny when you hit it. More or rather is goes numb and you can't move it for a few seconds. Maybe it is called this due to the fact that everyone else laughs at that person when they hit it. Anyway, all I can say is that it isn't funny and someone should change the name.
