One day a man found a battered lamp by the roadside. As he polished away the grime, a genii came streaming out of the burner in a pillar of flame.
"For liberating me from that prison, I will grant you any wish!" he cried.
"Make me the richest man in the world!" said the man.
And POOF! The genii took away his desire.
