One day a neighbor asked Mullah Nasruddin for his donkey.
Nasruddin not wanting to give him his donkey answered: "I'm very sorry, but somebody else has borrowed it, and the donkey is not here. "
Suddenly in this moment the donkey made a loud voice, behind a wall: iiiyyaahh !!
The Neighbor: "hey, you lied to me, there is the donkey ?!"
Nasruddin: "Whom would you rather believe, your Mullah or a donkey ?"
