Itoshiki, a high school teacher, explains to his class the concept of the Schrödinger’s Cat thought experiment.

This leads into a surreal discussion of how it is "better not to know" some things that form a part of your life. A businessman walks into the conversation to show off the box he placed on his head ten years ago; "My hair was beginning to look a little thin, so I placed this box on my head! Now the possibilities are limitless! Underneath this box, I could have a full head of hair... or I could be bald. But I'll never have to find out!"

The examples get sillier and sillier, until they visit Itoshiki's older brother and his new wife. It turns out that his brother has decided to wed 'Schrödinger’s Wife'.

"As long as the box isn't opened, I can continue having multiple possibilities of my ideal wife!"

One of Itoshiki's students grows curious, though, and 'slips' with her pen-knife, cutting the part of the box obsuring the wife's left arm. Undearneath is revealed a hairy, muscular arm.

Itoshiki's brother: "Oh no! The possibilities for my wife are reduced!" *images of his potential wife are updated to include one hairy arm"

Student: Oh dear! I slipped again! *cuts off the box obscuring the right leg of the wife*

A shapely, fishnet-clad leg is revealed.

Itoshiki's brother: "Argh! The possibilities are reduced even further!"

The student slips again, and cuts the back of the box. Gigantic, building-sized wings unfurl from the back of 'Schrödinger’s Wife' and begin to destroy the roof of the house.

Itoshiki: (screaming while running out the door) "I don't think humanity is prepared to see your wife!"
