It's an old story that we read in Class 3 but with a new ending.

A hat-seller who was passing by a forest 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 realized that all his hats were gone.

He looked up and to his surprise, the tree was full of monkeys and
they had taken all his hats.

The hat seller sits down and thinks of how he can get the hats down.
While thinking he started to scratch his head. The next moment, the
monkeys were doing the same.
