I Laughed

Language Alert...use of real anatomy words and not.
Oh my gosh. So the little man has Nerf guns. And he really likes to shoot us.  And so he has been told that until he stops doing that and shows control he is not getting a bee bee gun for Pat's  house.  He thinks the Nerf bullets don't hurt.  Well sometimes they do.
We are in the car and he says he is going to shoot his penis.  I tell him it will hurt.  He doesn't believe me and does it.  Guess what....it hurts.  I'm trying not to laugh because I know it does hurt, but he kind of deserves it.
A little side note...the other day he asked me what a ball sack was.  So I told him and explained how it holds the testicles and the slang for those is balls.  Hence ball sack.
After he is done lamenting the pain in his penis I say well good thing you didn't hit your ball sack.  And so he took that as a challenge.  You guessed it. 
Why do I have children who just don't believe me?  I guess we all have to learn life's lessons the hard way.
