There was once an Engineer who passed by a forest on his way back. Because of the poor economy, he was moonlighting as a hat-seller. 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 his side.
A few hours later, he was awakened by some sounds. The next thing he realised was that all his hats was gone. Then he heard some monkeys on top of the tree and he looked up. To his surprise, the tree was full of monkeys.They had taken all his hats!
The Engineer sits down and tries to think of how he can get the hats down. He started to think and scratched his head. The next moment, he realised that the monkeys were following same action. Next, he took off his own hat and fanned himself. The monkeys did exactly the same! An idea struck him - he took off his hat and threw it on the ground. And, the monkeys did the same too. And so he managed to get all his hats back.
Fifty years later, his granddaughter became a Quantity Surveyor cum hat-seller too and had heard this monkey story from her grandfather. One day, just like her grandfather, she passed by the same forest. Feeling very hot, she took a nap under the same tree and left the hats on the floor.
Again, when she woke up, she realised that all her hats were gone. She looked up and found that the monkeys had taken all her hats.
Remembering what her grandfather had told her, she started scratching her head and the monkeys followed. She took off her hat and fanned herself and again the monkeys followed. Now, very convinced of her grandfather's idea, she threw her hat on the floor, but to her surprise, the monkeys still held on to all the hats!
Then one monkey climbed down the tree, grabbed the hat on the floor, gave her a slap and said
"You think only you have grandfather meh........???!!!"
