I would say that the Principal has too much time on his hands if this is the kind of shit he is wasting his time on. I would e-mail a complaint to the Superintendent about this douchebag and copy the fucker on it. From my experience, you only need to do this once and it puts assholes like this in their place pretty quickly.
