Nasruddin bought a donkey and was leading it home. On the way, a thief stole the donkey and left his young son in the harness.
When he got home, Nasruddin was surprised to see his donkey had turned into a boy.
"For my bad behavior, my mother cursed me to become a donkey," the boy said. "But I repented, and now I'm human again."
"Make sure you don't misbehave in future!" Nasruddin said, sending the boy home.
The next day Nasruddin saw the same donkey at the market. "You bad boy!" said Nasruddin. "Didn't I tell you to behave yourself?"
