A father, mother, and son were going to Europe and were going to visit the nude beaches while they were there.

They didn't want the son to get a distorted view of beauty, so they told him, "The men with really big dicks and the girls with really, really big boobs were both really, 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.''
