The one-armed man is king. Unless he is so unfortunate that not only is he one-armed, but happens to sleep on the same side of the bed as he's missing an arm. In which case he is but a peasant.
But a one-armed man who has had the missing arm replaced by a robot laser cannon is once again king. Unless, of course, he lives in the land of people with robotic rocket launcher arms.
In which case he is target practice.
