I took my four year old son out to McDonald's for dinner one evening. As we were eating our hamburgers, he asked, "Daddy, what are these little things on the hamburger buns?" I responded that they were tiny seeds and were okay to eat.
He was quiet for a couple of minutes, and I could tell he was in deep thought. Finally, he looked up and said, "Dad, if we go home and plant these seeds in our back yard, we will have enough hamburgers to last forever."
