Dumber Man

One day, a kid's mom and dad took him to a nude beach. The kid went to play in
the water and came back a little while later and told his mom "I just saw a
woman who had bigger things than you do mom”. His mom replied, "The bigger the
woman's boobs the dumber the woman”.

So, the boy went out to play again, and came back a little while later and
said to his mom "Mom, I just saw a man who has a bigger thing than Dad”. His mom
replied "The bigger the thing, the dumber the guy."

So the kid went out to play again, then came back and told his mom "Daddy was
talking to a woman, and he kept getting dumber and dumber”.
