According to Partridge and the Morrises, the archetypical shaggy dog story involves an advertisement placed in the Times announcing a search for a shaggy dog. In the Partridge story, an aristocratic family living in Park Lane is searching for a lost dog, and an American answers the advertisement with a shaggy dog that he has found and personally brought across the Atlantic, only to be received by the butler at the end of the story who takes one look at the dog and shuts the door in his face, saying, "But not so shaggy as that, sir!" In the Morris story, the advertiser is organizing a competition to find the shaggiest dog in the world, and after a lengthy exposition of the search for such a dog, a
