A very ordinary man named Howard Mitla, who has a strange aptitude for Jeopardy!, is confronted by the bizarre sight of a human finger poking its way out of the drain in his apartment’s bathroom sink. He tries to deny the reality of what is happening, but the solitary digit eventually proves to be infinitely long and multijointed, capable of attacking him, and smart enough to hide whenever his wife, Violet, goes to the bathroom. Eventually, while Violet is at work, Howard burns it with a bottle of heavy-duty drain cleaner, then chops it to bits with a pair of electric hedge trimmers before dropping the pieces in the toilet. After this is done, Howard starts thinking about the creature and the hand to which it was attached. As he realizes it probably has multiple digits and that there are several openings in an average bathroom, an ominous sound is heard from the toilet.

Investigating reports of noise coming from Howard’s apartment, a police officer arrives to find him lying in a daze next to the toilet in a bathroom covered with blood. A police officer asks where the body is and he cryptically tells them, “If you have to go to the bathroom, I definitely suggest you hold it.” Just then, the toilet lid starts to shake from the inside. The story ends with the officer deciding to lift the lid to “wager it all” after Howard, in a shocked daze, laughs and asks, “Final Jeopardy. How much do you wish to wager?”
