There was a man in these shows who was called Mr. Bones because he carried two small sticks of bone that he used as an instrument. He was asked questions by one of the other men in the show, just to get stupid but funny answers. This became known as "pulling boners." But in time, the expression, "to pull a boner," meant something more than getting an answer to make you laugh. It meant a bad blunder a mistake that was costly. And a man who pulled such boners was often described as a "bonehead." less
