This is being widely dismissed as a fake but it's worth mentioning here just to note that it's being discussed all over the place. I've received the image several times over now. I am not going to make the call on its status, so just be aware this is making the rounds and to apply loads of salt. Maybe a little extra salt on top of that and be careful since we may be near a lethal dose.
Ive seen it posted all over, and several times in my box, phone, etc.
dakka, mexican ork, and many more places.
