    Once Effendi (阿凡提) had a joke with the prime minister (宰相). He said the minister would die the

next day. The next day it really happened that the Minister fell from his horse and died. When the king

heard this, he got angry and sent his men to catch Effendi at once.

    After Effendi had been brought to him, the king shouted angrily, "Effendi, since you knew my Minister

would die you must also know the date of your own death. Say it out, or you'll die today."
