A mother and her young son were flying Southwest Airlines. The little boy was looking out the window at all the planes on the ground when he turned to his mother and asked "If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?" The mother could not think of an answer, so she told her son to ask the flight attendant. The little boy walked down the aisle and asked the flight attendant the same question. The busy flight attendant smiled and asked "Did your mother tell you to ask me?" The boy said "Yes, she did." The flight attendant replied "Well then, you go and tell your mother there are no baby planes because Southwest always pulls out on time. Ask her to explain that to you".
