A mother and her very young son were flying Southwest Airlines from
Kansas City to Chicago. The little boy (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 airplanes have baby
The mother (who couldn't think of an answer) told her son to
ask the stewardess.
So the boy went down the aisle and asked the stewardess. The
stewardess, who was very busy at the time, smiled and said, "Did your Mom tell
you to ask me?"
The boy said, "yes she did."
"Well, then, you go and tell your mother that there are no baby airplanes because Southwest
always pulls out on time. Have your Mom explain that to you."
