Man.... I just sheared the head off of one of the screws that hold the right arm of my office chair in place. I want to be able to say that I work as hard as I play, but really it's because I have a habit of launching myself from my seat while bracing against the arms. Not so much the problem when I was "Mr. Kung Fu Guy", but "Mr. Beer and Cheese Guy" probably puts a little too much torque on small metal objects.
