Quoting Joss Whedon's Firefly is verboten at the University of Wisconsin-Stout, whose Professor Miller decorated his office door with a poster of starship captain Mal declaring (in reply to 'How do I know you won't kill me in my sleep?') his fair-play code: 'You don't know me, son, so let me explain this to you once: If I ever kill you, you'll be awake. You'll be facing me. And you'll be armed.' Campus police removed this in horror, threatening a charge of 'disorderly conduct'.
