The nude beach

.
> A mother and father took their 6-year-old son to a
> nude beach. As the boy walked along the beach,
> he noticed that some of the ladies had boobs
> bigger than his mother's, and asked her why. She
> told her son, "The bigger they are the dumber that
> 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 between their legs
than his dad. His mother replied, "The bigger they are the
> dumber that person is." Again satisfied with this
> answer, the boy returns to the ocean to play.
> Shortly after, the boy returned again. He promptly
> told his mother, "Daddy is talking to the dumbest
> girl on the beach and the longer he talks, the dumber
> he gets."
