One day the teacher asked the second grade class that if they had one square foot of land what would they grow and why did they think they could make money?
Jessica raised her hand, "I would grow apples." The teacher asked, "Why would you grow apples, Jessica?" "Because I could sell apples, sell apple juice, and feed myself." "Very good." The teacher replied.
Tommy raised his hand next, "I would grow oranges because I could sell the oranges, sell orange juice, and feed myself." "Excellent, Tommy." The teacher praised him.
Little Johnny raised his hand, "I would definitely grow hair." The teacher was a little puzzled, "How could you make money by growing hair?" Little Johnny replied, "I don't know, but my sister only has a triangle of hair, and she makes a lot of money!"
