Green's Theorem
     
         (TMRC) For any story, in any group of people there
        will be at least one person who has not heard the story.  A
        refinement of the theorem states that there will be *exactly*
        one person (if there were more than one, it wouldn't be as bad
        to re-tell the story).  The name of this theorem is a play on
        a fundamental theorem in calculus.
