PBS's The Conquistadores

Pizarro had made himself most unpopular with the Incas due to his incessant raping, pillaging and unfortunate tendency to slaughter the Indians and otherwise treat them like caca every chance he got. He demanded more and more gold while giving the Incas worthless crap, torture and death in return.

The Incan King, Atawallpa decided, quite wisely, that all the evil Spaniards had to die, except for 3 of them, whom he would merely castrate. These were, the horse breaker, the blacksmith and the barber.

Atawallpa felt that the barber had some kind of power, as he had seen many Spaniards line up outside the barber's tent. When they entered his tent they looked exhausted and scruffy but when they came out their faces were fresh as a baby's behind.
