See Photo-- What is Wrong in this Photo?

 One of the guys in the pix posted it on his Facebook profile and tagged several people. Surprisingly most people who saw the photo and commented on it criticized them.
               In fact the comments are so shocking and it's more like a war over there with over a hundred comments when last I checked... I see a pix of too friends chilling on a Sunday afternoon...lol. but people who have more eyes than me, claim they see more... Hian!

In your opinion is anything wrong in this photo?
