The ungrateful crane

One day as a crane, standing by a pond, saw a wolf, who looked in pain. The wolf came up and asked him if he would pull a bone out of his mouth, because it had gotten stuck in his throat. The crane agreed once the wolf promised to pay him a large amount of money in return for doing the favor. As soon as the crane had finished this horrendous task he demandingly asked for his reward of money. The wolf haughtily laughed and said, “Don’t you have a reward big enough, for I have been kind enough to let you safely pull your big, empty head from the jaws of a wolf. Surely you are not ungrateful for that!”
