Baby Planes Joke

A mother and her young inquisitive 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 dogs have baby dogs and cats have baby cats,
why don't planes have baby planes?"

The mother (who couldn't think of an answer) told her son to ask the
flight attendant. So the boy dutifully asked the flight attendant, "If dogs have
baby dogs and cats have baby cats, why don't planes have baby planes?"

The flight attendant responded, "Did your mother tell you to ask me
that?" The little boy admitted that she did. "Well, then, tell your mother that
there are no baby planes because Southwest always pulls out on time, and
she can explain that to you."
