The Selfish fish

Once upon a time there was a group of fish swimming in the pond happily. And every day a bear passes from there but a selfish fish teases the beat. The bear tried to catch the fish but the bear could not catch the fish. One day he took his head above the water to tease the bear but also the eagle saw the fish, caught him, got him and ate.

Moral- don't try to be over smart.
