On the first day of my first year class, a professor told us this joke:
Many years ago, a man who sold hats, walked from one village to another through a forest.
Tired, he rested under a large, shady tree. He did not notice the suddenly excited chattering above him and quickly fell asleep.
His hats lay beside him.
When the man woke up, he yawned and then turned to find that all his hats had vanished!
This time hearing the racket up in the tree, he looked up to see a tribe of monkeys – everyone of whom, wore his hats.
Worried out of his wits- for the hats were his livelihood- he wondered what to do. Finally, he remembered that he was still wearing on of his hats on his head. He looked up again at the monkeys and recalled what he knew of their habits.
Then he tore the hat off his head and threw it on the ground.
The monkeys, seeming much fascinated by this, pulled off the hats from their own heads and threw them on the ground as well!
The man, then, quickly picked them up and went hurrying out of the forest.
Now, in the present day, another hat-seller passing through the same forest, sat under the same tree and leaving his hats in a pile by his side, fell soundly asleep.
When he awoke, he found that his hats had disappeared. He looked up to the branches and saw a tribe of hat-wearing monkeys laughing at him.
Now, remembering that his grand-father had got into the same predicament many years ago, he pulled off his hat from his head and threw it on the ground.
A monkey climbed down the tree, picked up his hat and ran up to his friends again.
As the man gaped, bemusedly, up at them, the monkey laughed and said, ‘human, do you think you’re the only one who had a grandfather?’
