I took my 4 year old son, Jacob, out to McDonald's for dinner one evening for a "guy night".As we were eating our hamburgers, Jacob asked "Daddy, what are these little things on the hamburger buns?"I responded that they were tiny seeds and were ok to eat.He was quiet for a couple of minutes and I could tell he was in deep thought.Finally, Jacob looked up and said, "Dad, if we go home and plant these seeds in our backyard, we will have enough hamburgers to last forever."
