T here was a peacock who often boasted about his beauty. Everyday he walked to the banks of a large lake and looked his own reflections and said "Oh! What a beautiful bird I am! Look at my colourful tail". 

Once the peacock saw a crane on the banks of the lake. He said with a sneer to the crane, "What a colourless bird you are! You have no beautiful and colourful feathers like mine". 

The crane replied, "Of course! I don't have beautiful feathers. But, my feathers can make me fly across the lake. Can your feathers make you fly?" There was no reply from the peacock. 

MORAL : It is better to be useful than to be beautiful.
