It seems that most of Watson's pictures are with his tongue sticking out. Maybe it is too big for his mouth. I decided to post a few of these with the appropriate commentary. Hope you enjoy them as much as I do. Except maybe the last one
Sleeping Watson
Half-asleep Watson
Silly Watson
Evil Watson
Angelic Watson
Poop Watson (He even sticks his tongue out when he poops)
