Two parents take their son on a vacation and go to a nude beach.
The father goes for a walk on the beach and the son goes and plays in the water.
The son comes running up to his mom and says: 'Mommy, I saw ladies with boobies a lot bigger than yours!'
The mom says: 'The bigger they are, the dumber they are.'
So he goes back to play.
Several minutes later he comes running back and says: 'Mommy, I saw men with dingers a lot bigger than daddy's!'
The mom says: 'The bigger they are, the dumber they are.'
So he goes back to play.
Several minutes later he comes running back and says: 'Mommy, I just saw daddy talking to the dumbest lady I ever saw and the more and more he talked, the dumber and dumber he got!'
