Easy Jet Planes

A mother and her son were flying Easy Jet from Luton to Tenerife. 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 she had.

So she said, "Tell your mother that Easy Jet always pulls out on time."
