A mother and her 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 planes have baby planes?'
The mother, who couldn't think of an answer, told her son to ask the flight attendant.
So the boy went down the aisle and asked the flight attendant, 'If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?'
The busy flight attendant smiled and said, 'Did your mother tell you to ask me?'
The boy said, 'Yes, she did.'
'Well then, you go and tell your mother that there are no baby planes because Southwest always pulls out on time. Ask her to explain that to you.'
