Twenty-three years after scoring the winning touchdown for his college football team mild-mannered Harold Diddlebock, who has been stuck in a dull, dead-end book-keeping job for years, is let go by his pompous boss, advertising tycoon J.E. Wagglebury, with nothing but a tiny pension. Harold, who never touches the stuff, takes a stiff drink with his new pal... and another, and another. What happened Wednesday?
