In this fictional universe, Jonathan and Martha Kent's pickup truck has a flat tire caused by a nail. This prevents them from discovering the spaceship outside Smallville with the baby Kal-El, negating Superman. The story's theme is set in the first paragraph: For want of a nail the shoe was lost, for want of a shoe the horse was lost, for want of a horse the knight was lost, for want of a knight the battle was lost. So it was a kingdom was lost – all for want of a nail.
