All Smiles

I just love my boys and their always-keep-you-guessing-never-dull-for-a-minute-fun-loving attitudes.  Their big blue eyes and smiley faces are enough to make anyone's day.  You know what it NOT making my day?  The little scratch, piece of dirt or whatever is on my camera lens!  I have taken the camera apart and can't seem to figure it out.  Anyone have an idea for me?
