Once upon a time, there was a boy named Sam. He lived in a village surrounded by a forest.

Sam loved playing pranks on the villagers. One day, he thought of a mischievous plan.

He rushed into the village shouting, 'Wolf! Wolf! There's a wolf in the forest!'

The villagers got scared and ran to help Sam, but when they reached the forest, there was no wolf.

Sam laughed and said, 'Haha! It was just a prank! There was no wolf!'

The next day, Sam played the same prank again. He ran into the village shouting, 'Wolf! Wolf!'

The villagers rushed to help, but there was no wolf. They felt angry and fooled.

Finally, one day, a real wolf appeared in the forest. Sam saw it and got scared.

He shouted, 'Wolf! Wolf!', but this time, nobody came to help. The villagers didn't trust him anymore.

Sam learned his lesson. He realized that lying and playing pranks was not a good thing to do.
