All Earth needed was a good stiff dose of common sense, but its rulers preferred to depend on the highly fallible computers instead. As a consequence, interplanetary diplomatic relations were somewhat strained—until a nimble-witted young man from Mars came up with the answer to the "sixty-four dollar" question. The Martian colony, now independent but still economically controlled by Earth, sends an ambassador to the home planet. At this time, all decisions of any kind are made by computers, and all Earthlings are equal: equally ugly. Wearing masks, padding, and harnesses to make themselves unattractive, their main persuit is developing new allergies. The ambassador's task is to free Mars from Earth control. Since Earth is run by machines, he assaults the machines.
