The perfect exam question

Comes to us from Chicago, via Joseph Epstein in today's WSJ.  The city of Chicago has banned foie gras.  Epstein writes:

"A Chicago alderman named Joe Moore, who sponsored the ban on foie gras, after its passage declared that it sends "a powerful message that we [in Chicago] uphold the value of a civilized society." All too easily can I hear one of the red-faced, pot-bellied Chicago aldermen of my youth, reply, "What's he, [epithet deleted] nuts!?""

As a trade law instructor, one is tempted to just add to the bottom, "Discuss."
