Whether it’s executed in a complex, long-form work like a novel, or a simple one-line joke, Analogy must always be used the same way: the two things being compared must be very different; one of them must be revealed literally while the other must be kept secret; and you must make the reader aware of as many points of comparison as possible between the two. Each instance that calls to mind the hidden side of the Analogy creates a joke in your writing.
