Mimsy's Joke

"Mimsy's Joke" by Millard Grimes is a science fiction short story published in the early 1950s. The narrative centers around Oscar Nance, a prominent archaeologist who embarks on a historic expedition to Mars, led by a stern military commander. The story delves into themes of discovery and the unexpected nature of exploration, focusing on the fate of the Martian civilization and their ironic relationship with Earth. As Nance and his team explore Mars, they encounter Staang, a Martian who reveals that Earth has been unknowingly inhabited by the descendants of ancient Martians—dogs, which have become the lazy remnants of a once-great civilization. The story unfolds as Staang narrates the history of the Martians and their secretive invasion of Earth, leading to a humorous yet thought-provoking realization for the explorers. By the end, the expedition is left with the ironic understanding that they have been the subjects of an age-old joke, forced to confront their ideas about intelligence and servitude as they plan their return to Earth to share this startling revelation.
