There was once a hat seller who passed through the forest. The weather was very hot and he decided to take a nap under one of the trees, so he left his whole basket of hats by the side.
A few hours later, he woke up and realised that all his hats were gone. Then he heard some monkeys on top of the tree and looked up. To his surprise, the tree was full of monkeys. They had taken all his hats! The hat seller sits down and try to think on how he could get the hats down. He started to think and scratched his head. The next moment, he realised that the monkeys were doing the same thing. Next, he took down his own hat and fanned himself. The monkeys did exactly the same. Then an idea struck him, he took his hat and threw it on the floor, the monkeys did the same too.
Happily, he quickly collected all his hats back.

Fifty years later, his grandson also became a hat seller and also got to hear the monkey story from his grandfather. One day, just like his grandfather, he passed through the same forest.
Feeling very hot, he took a nap under the same tree and left the hats on the floor.
Again, when he woke up, he realised that all his hats were gone. He looked up and found that the monkeys had taken all his hats. Remembering what his grandfather told him, he started scratching his head and the monkeys followed. He took down his hat and fanned himself and again the monkeys followed.
Now, very convinced of his grandfather's idea, he threw his hat on the floor, but to his greatest surprise, the monkeys still held onto all the hats.

Then one bold monkey climbed down the tree, grabbed the hat on the floor and sneered, "You
think say na only you get grand papa?"
