Once a thirsty crow was flying around in search of water. It flew many many miles until it found a jug with little water in it. When it tried to drink it couldn't reach the water at the bottom because the jug had narrow opening. It tried to push the jug so the water could flow out but the jug was too heavy for him. It did not give up. It searched around to see a way to drink the water. When it saw pebbles it got an idea. It put each pebble in the jug to raise the water level. When the water was high enough for it to drink, it jumped with joy. The crow drank the water happily and flew away. 

Moral: Never give up. Where there is a will there is a way.
