it's my life

A couple with their young son, Little Johnny, decided to spend a day at a nude beach. After an hour in the sun, the father went for a walk while Little Johnny played in the water.
After a while Little Johnny came up to his mother and said, "Mommy, I saw ladies with boobies a lot bigger than yours!"
The mother said, "The bigger they are, the dumber they are."
So Little Johnny went back to play. Minutes later Little Johnny returned and said, "Mommy, I saw men with dingers a lot bigger than daddy's.
The mother said the same thing, "The bigger they are, the dumber they are."
So the boy went back to play. Several minutes later Little Johnny ran back to his mother and said,"Mommy, I just saw daddy talking to the dumbest lady I ever saw, and the more he talked, the dumber he got!"
