Case in point, the Maryland Court of Appeals recently quoted the Seinfeld episode where Jerry returns a wig out of spite in a footnote in an opinion:
Clerk: I don't think you can return an item for spite.
Jerry: What do you mean?
Clerk: Well, if there was some problem with the garment. If it were unsatisfactory in some way, then we could do it for you, but I'm afraid spite doesn't fit into any of our conditions for a refund.
