The general consensus was that this functionless appendage should be amputated due to concerns about its lack of circulation and vitality – though Santos simply strapped the limb to his thigh in a special sling so that he could remain active and ride horses.

The exhaustive examinations Santos received throughout his life confirmed that he could not only urinate but also achieve erections with both of his members simultaneously.

One is bad enough. Ha ha
