why don't big planes have baby planes?

[RealPotential]

One day, a little boy asked his mom, "Momma, if big kitties have baby kitties, and big doggies have baby doggies then why don't big planes have baby planes?" The mom replied, "I don't know hon. Why don't you ask the stewardess!" So the little boy went up to the plane stewardess and asks, "If big kitties have baby kitties and big doggies have baby doggies then why don't big planes have baby planes?" The stewardess then said, "Because, little boy, Southwest Airlines always pulls out on time."
