Growing up, we lived across from a field and there would always be tractors tilling the soil. As the tractors would move along, flocks and flocks of seagulls would follow and try to eat whatever was being churned up. One day when I was very young, my family and I were watching this and I stated very matter of factly that "tractors make seagulls"
I thought I was so smart for figuring that out on my own.
