In Gilmore Girls, describing a debutante ball: "It's like animals being up for bid at the county fair, except sheep don't wear hoop skirts."
This kind of over-the-top, facetious detail is used throughout the show and fuels the witty dialogue. Is there a word for humor created by such an unexpected, specific detail?
This question suggests "facetious synecdoche," but I don't think the example above is synecdoche (except for "sheep" being representative of "animals", but it's really the "hoop skirts" that drives the humor). I'm also not looking for: "detail," "imagery," "satire," "hyperbole."
