A lesson about the "birds and the bees"

[1ViciousGSX]

A mother and her son were flying Southwest Airlines from El Paso to San
Diego. 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
stewardess. So the boy walked back to the flight attendant and asked,
"If big dogs have baby dogs and big cats have baby cats, why don't big
planes have baby planes?"

The stewardess responded, "Did your mother tell you to ask me that?"
The boy said, "Yes, she did."
"Well then, tell your mother that there are no baby planes because
Southwest always pulls out on time. Have your mother explain that to
you."
