A mother and her young curious son were flying Sou

A mother and her young curious son were flying Southwest Airlines from Las Vegas to Chicago. The boy sitting by the window turned to his mother and asked, "If dogs have baby dogs and cats have baby cats, why don't planes have baby planes?"

The mother was caught by surprise and couldn't think of an answer so she tells her son to ask the flight attendant. So the boy dutifully asked the flight attendant the same questions.

The flight attendant responded, "Did your mother tell you to ask me that?"

The little boy said, "Yes."

"Well then, tell your mother that there are no baby planes because Southwest always pulls out on time. Now, let your mother explain that to you."
