A neighbor called on Nasrudin.
‘Mulla, I want to borrow your donkey.’
‘I am sorry,’ said the Mulla, ‘but I have already lent it out.’
As soon as he had spoken, the donkey brayed. The sound came from Nasrudin’s stable.
‘But Mulla, I can hear the donkey, in there!’
As he shut the door in the man’s face, Nasrudin said, with dignity: ‘A man who believes the word of a donkey in preference to my word does not deserve to be lent anything.’
I’m going to use this reasoning
Like Indian poet Ghalib once refused to eat mangoes and as his friends threw the peels in a corner a donkey came, sniffed them, and started munching them with eagerness. At this his friends teased Ghalib saying, “Look even donkeys like mangoes!” Ghalib got up and said, “only donkeys like mangoes” and left smiling 
Oh most definitely this one is a keeper, go Ghalib!
