Baby Planes

A mother and her 5 yr old son were flying Southwest Airlines from Denver to Dallas.

The son (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 walks to the galley and asks the flight attendant, 'If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?

The flight attendant responded, 'Did your mother tell you to ask me?'

The boy said, 'Yes, she did....'

'Well, then, please tell your mother that there are no baby planes because Southwest always pulls out on time. Have your mother explain that to you.'...
