There is Something Missing

Does anyone notice something missing in this picture?  Brian told me I was mean for posting this but I think it's priceless.  

I had to take this picture.  We were getting ready to go up to Stow so we were sneaking in during nap time.  My dude apparently decided to depants himself and air out his back side.  Brian didn't even notice till I pointed this naked little tushy out.  I love him!  My sweet, naked bottomed boy.
