Football is an insane game dreamed up by a maniac and altered by generations of maniacs, each more maniacal than the last. There is an oblong ball that bounces irregularly. The rules have become so complicated that the concept of a catch has transcended the empirical to the realm of metaphysics. They play in withering heat and blizzards, on grass and artificial turf, in front of tens of thousands of bellowing football zealots, in a flurry of flying limbs and football equipment and those inscrutable playcalling cards that show a walrus, the HMS Bounty, Chester A. Arthur, and Herm Edwards dressed as his alter-ego The Herminator.
