The Knights of Arthur

The Knights of Arthur by Frederik Pohl, published in 1958, is a humorous sci-fi tale. The sum total population of the entire U.S. is now less than 10,000(!) as the listener is taken on a wildly funny ride, an Arthurian quest, actually; but of a very eccentric nature indeed, as Arthur is an entity with very strong and particular opinions...without body and limbs, by the way.
