The rule in rugby union (section 10, paragraph 4, part k) that lets a referee penalise "unsportsmanlike behaviour", which is handy if you have nfi why you just blew the whistle. From the players' point of view, it's a bit dodge because it gives the ref the power to blow anything. It is perhaps this frequent blowing that has led to speculation that all referees are gay.
