Baby Planes

A mother and her 5 yr old son were flying Southwest Airlines from
Kansas City to Chicago. The son (who had been looking out the window)
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, who couldn't think of an answer, told her son to ask the
stewardess.

So the boy walks to the galley and asks the stewardess, "If big dogs
have baby dogs and big cats have baby cats, why don't big planes have
baby ! planes?"

The stewardess responded, "Did your mother tell you to ask me?"

The boy said, "Yes, she did...."

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