In this clever tale, Pa gives his three children a challenge. He declares with a chuckle, "If one of you can fill the barn for a penny, I'll give you the farm and go sleep in the chicken coop!" Clearly, Pa doubts any of his children will succeed. Of course, that just makes Bill, Bob, and Penny even more determined to win. Each of the children thinks long and hard and comes up with an idea-but only Penny's plan is ingenious enough to restore harmony to the family.
