"The Fisherman and His Wife" is a German fairy tale collected by the Brothers Grimm, tale no. 19. It is Aarne–Thompson type 555, the fisherman and his wife. Its theme was used in The Tale of the Fisherman and the Fish, an 1833 poem by Aleksandr Pushkin. Virginia Woolf has her character Mrs. Ramsey in To the Lighthouse read a version of the story to her son, James. Günter Grass's 1977 novel, The Flounder, is loosely based on the fairy tale, as are Emanuele Luzzati's version, Punch and the Magic Fish, and Ursula LeGuin's novel The Lathe of Heaven.
There is a poor fisherman who lives with his wife in a hovel by the sea. One day the fisherman catches a golden flounder, which claims to be an enchanted prince, and begs to be set free. The fisherman kindly releases it. When his wife hears the story, she says he ought to have had the flounder grant him a wish, and insists that he go back and ask the flounder to grant her wish for a nice house.
The fisherman returns to the shore but is uneasy when he finds that the sea seems to becoming turbid, as it was so clear before. He makes up a rhyme to summon the flounder, and it grants the wife's wish. The fisherman is pleased with his new wealth, but the wife is not and demands more, and demands that her husband go back and wish that he be made a king. Reluctantly, he does, and gets his wish. But again and again, his wife sends him back to ask for more and more. The fisherman knows this is wrong but there is no reasoning with his wife. He says they should not annoy the flounder, and be content with what they have been given, but his wife is not content. Each time, the flounder grants the wishes with the words: "just go home again, she has it already" or similar, but each time the sea grows more and more fierce.
Eventually, the wife wishes to command the sun, moon and heavens, and she sends her husband to the flounder with the wish "I want to become equal to God". When that final wish is made, the flounder say: "just go home again, she is already sitting in the old hovel again". And with that, the sea becomes calm once more.
A short cartoon based on this story was part of the United States animated television series, Rocky and Bullwinkle Show. The Flounder was replaced by a beautiful mermaid who grants the wishes in exchange for her freedom. Additionally, the wife goes directly from queen to wishing to be a 'goddess'. The mermaid points out to the fisherman that all his wishes have been for his wife, and asks him what he desires. The fisherman replies that he just wants his wife to be happy, and the mermaid replies, "Go; she is happy." As in the later 1997 version, the fisherman and his wife are reduced to living in their hovel, but the wife is happy that it is poor yet neat.
In 1997, the story was given a Spanish-flavored adaptation on the animated cable series, Happily Ever After: Fairy Tales for Every Child. Edward James Olmos and Julia Migenes provided the voices of the fisherman and his wife. In this version, the fisherman is unable to figure out what his last wish is, and says, "I want only for my wife to be happy". Immediately, he and his wife are reduced to living in the hovel again. She is content and happily embraces him.
The Timon and Pumbaa cartoon episode "Be More Pacific" is based on this story, with Pumbaa's role paralleling the fisherman's and Timon's role paralleling the wife's. Pumbaa finds and rescues a magical whale named Lester, who grants him three wishes. Pumbaa asks for nothing for himself, but he does relay Timon's wishes to Lester. First Timon wishes for "something big and expensive" and is given the Statue of Liberty. Then he wishes to be a king and is transformed into a giant. Lastly he wishes to be "a regular-sized king in a stone castle with a ferocious fire-breathing monster that he can defeat," but Pumbaa gets the message wrong and says "can't" instead of "can." The ferocious monster turns out to be a fire-breathing chicken (instead of the dragon that Timon actually meant), and after several futile attempts to defeat and escape it, the episode ends with Timon searching for another wish-granting fish while Pumbaa struggles to hold down the trapdoor separating them from the monster.
"The Fisherman and his Wife", is arguably a story intended to convey the moral that material goods do not bring contentment: The person who is dissatisfied with little will also be dissatisfied with much. Likewise the person who is happy, or content, with much will also be happy with little.
A reading may be possible where the final situation is not (only) a punishment for the one wish that went too far, but an actual fulfillment of the wish. After all, though the wife thinks about moving Sun, Moon and stars, the actual wording of her wish is "I want to be equal as to God". Note that, in Christian views, Man has been created according to the image and likeness of God in the beginning, and that God became Man to live in poverty (and eventually die on the cross). In this case, the couple would be granted the wish to become Man (as God had done), that is, revert to their original situation (which in their, and in many men's, case includes poverty). In this case, the moral would be not to imagine Godhead as a sort of increased form of Emperorhood and the like.
