"The Electric Monk was a labour-saving device, like a dishwasher or a video recorder. Dishwashers washed tedious dishes for you, video recorders watched tedious television for you, thus saving you the bother of looking at it yourself; Electric Monks believed things for you, thus saving you what was becoming an increasingly onerous task, that of believing all the things the world expected you to believe."
--Douglas Adams, Dirk Gently's Holistic Detective Agency
The advanced alien race that invented these sophisticated androids chose to give them an otherworldly look eliminating any chance someone could mistake them for actual living beings. By a curious coincidence, this made Electric Monks dead ringers for inhabitants of the planet Earth, which is exactly where one of them is transported through a time-space warp.
