Laughing Eye and Weeping Eye or The Lame Fox is a Serbian fairy tale collected by Albert H. Wratislaw in his Sixty Folk-Tales from Exclusively Slavonic Sources, number 40. Andrew Lang included it in The Grey Fairy Book. Parker Fillmore included the tale as The Little Lame Fox in his book Jugoslav Fairy Tales. Synopsis A man once always had one eye weeping and the other smiling. He had three sons, of whom the youngest was rather foolish. One day, out of curiosity, the sons each asked why one eye was weeping and the other smiling. The father went into a rage, which frightened off the older two but not the youngest. So the father told the youngest that his right eye smiled because he was glad to have a son like him, but his left eye wept because he once had a marvelous vine in his garden, and it had been stolen. All three sons set out to find it, but the youngest parted with his older brothers at a crossroads. A lame fox came up to the older brothers to beg bread, and they drove it off with sticks; it went to the younger, and he fed it. It told him how to find the vine, and to dig it up with a wooden shovel rather than an iron one. He thought the wooden shovel would not be strong enough, but the noise the iron shovel made woke the guards. His captors told him he could have the vine if he brought them a golden apple. He went back to meet the fox, who told him where it was, and to use the wooden rather than the golden pole to get it, but he used the golden pole, which woke the guards. They told him he had to bring them a horse that could circle the world in a day. The fox told him where to find it, and to use the hempen halter rather than the golden one. He failed again, and his new captor told him he could be free if he brought him a golden maiden who never saw the sun or moon. He persuaded the man to lend him to the horse to help find her. The fox led him to a cave where he found such a maiden. He brought her out and to his horse. The fox said it was a pity
