     Long ago, there was an interesting man called Effendi (阿凡提), He had a good sense of humour.

One day he had a joke with the Prime Minister (宰相). He said that the Minister would die the next day.

Really the next day, the Minister fell off the horse and died. When the king learned this, he got angry and

sent his men to catch Effendi at once.

     When Effendi was in front of the King, the king shouted angrily, "Effendi, since (既然) you know

when my Minister would die, you must know the date of your own death. Say it out, or you will die

today."Effendi looked at the king for a while, he answered, "But how can I know? I'll die two days earlier

than you."Because the king was afraid if he killed Effendi, he himself would die after that. He thought he

must keep Effendi alive as long as he could, so he let Effendi go.
