A mother and her son were flying DELTA Airlines from Kansas
to Chicago. The son (who had been looking out the window) turned to his
mother and said, "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 asked the stewardess, "If big dogs have baby
dogs and big cats have baby cats, why don't big planes have baby planes?"

The stewardess asked, "Did your mother tell you to ask me?" He said
that his mother had. So the stewardess said, "Tell your mother that
Delta always pulls out on time."
