Some boys were playing around a pond when they spotted a group of frogs hopping and swimming about in the water. The boys began to throw rocks at the frogs and even competed against each other as to who could hit the most frogs. Sometimes the rocks hit the frogs so hard that they died.

     Finally one frog hopped upon a lily pad.
     "Please stop," he pleaded, "What may seem just fun to you is death to us."
