Lisa has a new desk. She asks Billy to put it together for him. Billy is happy to do it, but he doesn't think he needs to follow the designer's directions, so he tosses them aside. Later Lisa comes back to see how Billy's doing, but the desk is an absolute mess. Lisa explains why Billy should always follow the designer's directions. The one who created it knows more about the product than anyone else. Billy learns his lesson, follow the directions, and put the desk together just the way it was supposed to be.
