The Good Bargain

Is it a good bargain to throw money to the frogs in the pond and then complain about the frogs’ behavior? Is it smart to give a slaughtered cow to the dogs and then expect something in return? Isn’t it a great luck to make the princess laugh and get her hand only cause of this? Well it may be, if the farmer in our story wanted the princess’s hand. Which he apparently doesn’t. What happened after that? Did the king punish the insolent farmer? Is the farmer stupid enough to not accept the better life he gets offered or he is about to make even greater bargain?
