There were three blind men walking, along the way one of them kicked a whistle and then he picked it up. He said "my friends I have picked a whistle".
He whistled once his one eye opened he also whistled the other eye opened and then he shouted " Oh my gosh I whistled and I can see things but not so clearly"
All of his friends also whistled and each one's eyes opened but they couldn't see clearly.
Then the first blind said " Give it to me I'm going to whistle again and see if I can see very well"
Once he whistled, he at once became blind as usual. He then said "Oh my friends as I whistled the first, everyone is going to whistle again"
*Moral*: Being too ambitious leads to deception.
