Once upon a time there were a fisherman and his wife who lived together in a filthy shack near the sea. Every day the fisherman went out fishing, and he fished, and he fished. Once he was sitting there fishing and looking into the clear water, and he sat, and he sat. Then his hook went to the bottom, deep down, and when he pulled it out, he had caught a large flounder.
Then the flounder said to him, "Listen, fisherman, I beg you to let me live. I am not an ordinary flounder, but an enchanted prince. How will it help you to kill me? I would not taste good to you. Put me back into the water, and let me swim."
"Well," said the man, "there's no need to say more. I can certainly let a fish swim away who knows how to talk."
With that he put it back into the clear water, and the flounder disappeared to the bottom, leaving a long trail of blood behind him.
Then the fisherman got up and went home to his wife in the filthy shack.
"Husband," said the woman, "didn't you catch anything today?"
"No," said the man. "I caught a flounder, but he told me that he was an enchanted prince, so I let him swim away."
"Didn't you ask for anything first?" said the woman.
"No," said the man. "What should I have asked for?"
"Oh," said the woman. "It is terrible living in this shack. It stinks and is filthy. You should have asked for a little cottage for us. Go back and call him. Tell him that we want to have a little cottage. He will surely give it to us."
"Oh," said the man. "Why should I go back there?"
"Look," said the woman, "you did catch him, and then you let him swim away. He will surely do this for us. Go right now."
The man did not want to go, but neither did he want to oppose his wife, so he went back to the sea.
