A mother and father take their 6 year old son to a nude beach.
As the boy walked along the beach, he noticed that many of the ladies had
boobs bigger than his mother's so he told his mother just that. She told her
son, "The bigger they are, the dumber the person is." The boy, pleased
with the answer, goes to play in the ocean but returns to tell his mother that many of the men have larger things than his dad does. His mother replied, "The bigger they are, the dumber the person is." Again satisfied with her answer, the boy returns to the ocean to play. Shortly after, the boy returned again, and promptly tells his mother:"Daddy is talking to the dumbest girl and the longer he talks, the dumber he gets."
