There was once a man who had a very selfish and unkind son. So one day the father sent his son to the market with one coin and said, “I am sick and tired of your selfish ways. Take this coin and buy with it: something to feed the cows, something to plant in the garden, something for us to eat, and something for us to drink. Don’t come back until you do this!” He is only allowed to buy one item.
What did he buy that fulfilled his father’s wish?
He bought a watermelon – the juice to drink, the pulp to eat, the seeds to plant in the garden, and the rind to feed the cows!
