Procrustes

The most interesting of Theseus's challenges came in the form of an evildoer called Procrustes, whose name means "he who stretches." This Procrustes kept a house by the side of the road where he offered hospitality to passing strangers. They were invited in for a pleasant meal and a night's rest in his very special bed. If the guest asked what was so special about it, Procrustes replied, "Why, it has the amazing property that its length exactly matches whomsoever lies upon it." What Procrustes didn't volunteer was the method by which this "one-size-fits-all" was achieved, namely as soon as the guest lay down Procrustes went to work upon him, stretching him on the rack if he was too short for the bed and chopping off his legs if he was too long. Theseus lived up to his do-unto-others credo, fatally adjusting Procrustes to fit his own bed.
