THE WATER PUMP
Many years ago A.J. Gordon went to the World’s Fair. From a distance he saw a man pumping water with one of those old hand pumps. The water was pouring out and he said as he looked, "That man is really working hard at pumping water."
But when he got closer, he discovered that it was a wooden man connected to a pump that was powered by electricity.
The man was not pumping the water; the water was pumping him.
