Ship Shape

Michelle, is the commander of a Coast Guard cutter. When she gave her dad, Bob, a tour of her ship, he was impressed with the neatness of all decks. However, when Michelle brought Bob to her house, he couldn't believe the disorganization. "Why is everything in its place on your ship," he asked, "but your house is such a mess?" Michelle replied, "My house doesn't take 30-degree rolls."
