A man, his wife, and his son all go to a nuude beach. Naturally, the young son has lots of questions. He runs to his father, “Dad! Dad! All of the women have these things hanging from their chests!”
His father tells him, “Son, those are breasts. The women with large ones are dumb and the small ones are smart.”
Soon after the son comes running again, “Mom! Mom! All of the guys have these things dangling between their legs!”
The mom replies, “Those are called p*nis’. The men with the big ones are dumb and the men with small ones are smart.”
A little bit later the son runs up to his mom and asks her, “Mom! Mom! Is being dumb contagious? Dad is talking to a really dumb lady and he keeps getting dumber and dumber.”
