Why don’t skeletons ever go trick-or-treating?
Why this joke works
A Companion Hidden in No Body
No body sounds like nobody, the word for having no companion. The answer offers an ordinary social reason for staying home while also pointing to the skeleton's bare-bones appearance. In a Halloween cartoon, the missing flesh becomes a missing body, even though a real skeleton is itself part of a body. That deliberately loose picture makes the word split work. The laugh comes from a costume-like character's predicament rather than anything frightening happening to a person.
A closer look
A Closer Look
The space between no and body is visible in writing but almost disappears in speech. On a card, keep the two words separate so the visual clue survives. When telling it aloud, a tiny emphasis on body is enough. A cheerful skeleton illustration helps keep the scene playful; gruesome detail would distract from the very mild language trick.
Fact behind the joke
Fact Behind the Joke
Cambridge Grammar classifies nobody as an indefinite pronoun and notes that it takes a singular verb. It has the same basic meaning as no one. Separating no body changes the grammatical structure into a negative word followed by a noun, which gives the skeleton answer its visible written twist.
