G.P.S. didn’t always stand for Global Positioning System, you know.
In the beginning, it stood for the Grunting and Pointing System, used by cave men to indicate the nearest watering hole.
By the horse-and-buggy era, G.P.S. had evolved into a different navigation technology: Guidance by Pony Sense.
In the automobile age, G.P.S. came to mean Grumbling by Peeved Spouse. ("Why won’t you just stop and ask?")
