This rich man in one of the villages of Iran had a donkey which he adored very much. For some reason his donkey became very sad and this bothered the rich man very much. He placed an ad in Kayhan ( National newspaper in Iran) that whoever makes my donkey laugh gets 1000 tomman. People from everywhere show up, but all attempts result in faliure, but just as the rich man was getting disappointed this Turk appears. The Turk goes and says something in donkey's ear and the donkey starts to laugh the rich man was amazed and tells the Turk that he will get an additional 1000 toman if he tells the rich man how he did it.
The Turk agrees and says:" I told the donkey that my penis is larger than its".
This time the rich man says I'll give you another 1000 if you make my donkey cry. There goes the Turk to the donkey and after couple of seconds the donkey started to cry very hard. This time the rich man tells the Turk that if the Turk tells him what he told the donkey he would grant the Turk all his wealth.
The Turk say this time I simply showed the donkey my penis....
