BACKGROUND--FIELD OF INVENTION

[0001] This invention relates to traditional and ancient 52 "playing card" decks being inscribed with an equally traditional and ancient human recreation known as telling "jokes".

The "inventor" further explains what he is claiming, and what he isn't:

A joke which is able to be expressed in words and/or reduced to printed form (as distinct from "practical jokes" however demonstrated, or cartoons of visual form) are defined as a group of words designed to arouse laughter. Such Individual jokes are not subject to copyright unless a person is able to claim (and usually prove) that he or she is the creator.

Absent this, the law does not afford even copyright protection to a joke: only the form of the individual presentation as the visual form of a book, a poster or some other format: even a card, playing or otherwise. No doubt even I will seek copyright protection for specific individual printed parts of my future production of decks of playing cards inscribed with jokes.

Well, that's a relief.
