A father, mother, and son were in Europe and decided they'd visit some nude beaches. They didn't want the son to get a distorted view of beauty, so they told him that men with really big units and girls with really big breasts were both really dumb. When they got to the beach they split up. Later, the mother saw the son and asked where his dad was. The boy said, "Well, the last time I saw him he was talking to this really, really dumb blonde, and the longer they talked, the dumber he got."
