The fisherman's wife and escalating wishes
An old fisherman frees a golden fish that grants wishes; his wife demands a new trough, then a house, then noblewoman status, then to be tsaritsa, and finally to be mistress of the sea with the fish as her servant. At the last demand the sea darkens, and the fisherman returns to find her sitting again before the same broken trough in their dugout. Each granted wish resets her baseline, so satisfaction never arrives and the final overreach revokes every gain at once.
