The Knights of Arthur

The Knights of Arthur is a humorous sci-fi tale by Frederik Pohl. The inhabitants of the entire U.S. is now less than 10,000(!) as the listener is carried onto a madly hilarious ride, an Arthurian quest, actually; but of a very peculiar nature indeed, as Arthur is an entity with very strong and outspoken particular opinions, also missing body and limbs, by the way.
