And lo! Supreme Plumbling was created, and it was established on Fourth Street, in Saint Louis, Missouri, nigh unto the White Castle, somewhat close to the shadow of the Arch, and all the other plumbers gave way, yielding to its supremacy.

He gathered up his pipes and attached them to a single Great Bowl. He filled it with a magical substance that the Powers of Darkness strove to suppress. He put fire to the bowl and drew upon it, blowing its smoke upon his companion in wisdom, Elbow Joint the Owl, who thereupon straightaway entered oblivion.
