The Fisherman and the Sprat

A Fisherman cast his net into the sea, and when he drew it up again it contained nothing but a single Sprat that begged to be put back into the water. "I'm only a little fish now," it said, "but I shall grow big one day, and then if you come and catch me again I shall be of some use to you." But the Fisherman replied, "Oh, no, I shall keep you now I've got you: if I put you back, should I ever see you again? Not likely!"
