"Not if I can help it. The fellow bears pain with wonderful fortitude. When I was in Yucatan, and had to slash my face to get out the poisoned darts of the cactus, I screamed till you could have heard me a mile. And I had no anaesthetic to soothe me. Your lieutenant never whimpered or cringed with his mangled foot and he refused morphine when I operated on it. But I fooled him. I hate to see a brave man suffer. I stuck a needle just above the wound when he wasn't looking, and I've doped his medicine ever since."
