Thirsty crow

Once a crow was very thirsty. He flew here and there in search of water. But he found nothing. At last, he reached a garden. He saw a pitcher of water there. There was some water at the bottom of the pitcher of water there. The crow’s beak could not reach the water. He was very Wise. He hit upon an idea and collected some pebbles and put them into the pitcher one by one. The water rose up slowly. The crow quenched his thirst and flew with pleasure.

Moral:

Necessity is the mother of invention.
