On Christmas Eve, Nathan thought it would be nice to buy his wife a little gift for the next day. Always short of money, he thought long and hard about what that present might be. Unable to decide, Nathan entered a department store and in the cosmetics section he asked the girl, “How about some perfume?” She showed him a bottle costing $75. “Too expensive,” muttered Nathan. The young lady returned with a smaller bottle for $50. “Oh, dear,” Nathan groused. “Still far too much.” Growing rather annoyed at Nathan’s meanness, the salesgirl brought out a tiny $10 bottle and offered it to him. Nathan became really agitated. “What I mean,” he whined, “is I’d like to see something really cheap.” So the sales girl handed him a mirror.
