There was a young couple living in a Nudist Colony when one day, their five year old son comes running up to his Mother.
"Hey Mommmy!", said her son, "Those things that Women have on their chests..how come some are bigger and some are smaller?"

Thinking a moment his mother said, "Well son, the bigger they are the dumber the woman is."

"oh", said her son,"Well, what about those things men have between their legs? How come some of THEM are bigger and some are smaller?"

"Well son", said the mother, "It's just the opposite. The bigger they are the smarter the man is."

Puzzled, the mother asked, "Why do you ask son?"

"Oh..well I just saw Daddy out back talkin' to this REALLY dumb woman and he's gettin smarter and smarter!"
