There was once a hat-seller who passed by a forest on his way back.The 
weather was very hot and so 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 by some sounds. The next thing he realised 
was that all his hats was gone. Then he heard some monkeys sound on top 
of the tree. He looked up! To his surprise, the tree was full of monkeys
and they had taken all his hats. 

The hat-seller sits down and think of how he can get the hats down. He 
start scratching his head. The next moment, he realised that the monkeys
were doing the same action. Next, he took down his hat and fan himself
and the monkeys do exactly the same. An idea came to him, he took his 
hat and throw it on the floor and the monkeys do that too. So he finally
managed to get all his hats back. 

Fifty years later, his grandson also became a hat-seller and had heard 
this monkey thing from his grandfather. One day, just like his grandfather,
he passed by the same forest, very hot, 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 realised that the monkeys had taken all his hats. Remember
what his grandfather had told he start scratching his head and the monkeys
follows. 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 surprise, the monkeys still hold on to all the hats. Then one 
monkey climbed down the tree, grap the hat on the floor, gave him a slap and
said "You think only you have grandfather meh".
