Once, a cap seller was passing through a jungle. He was dead tired and needed to rest. Then, he stopped and spread a cloth under a tree. He placed his bag full of caps bear him and lay down with his cap on his head. The cap seller had a sound sleep for one hour. When he got up, the first thing he did was to look into his bag. He was startled when he found all his caps were not there. He was wondering where they could have gone. Indeed, he was greatly puzzled. When he looked up the sky, he was very surprised to see monkeys sitting on the branches of a tree, each wearing a cap on his head. They had evidently done it to imitate him. He decided to get his caps back by making a humble request to the monkeys. In return, the monkeys only made faces of him. When he began to make gestures, even when he raised his fist towards them to threaten them, they also imitated him.

    At last he hit upon a clever idea. "Monkeys are a great imitator," he thought. So he took off his own cap and threw it down on the ground. As he had expected, all the monkeys took off the caps and threw it down on the ground. Quickly he stood up and collected the caps, put them back into his bag and went away.
