I'm not accusing any of me of being sharper than you, and when I have to explain, it's not funny anymore but if you harken back to the guy who was posting pictures of his safe and gun room and I made some knowing comments about the casual dress of the photographer and none of you caught on and I gave up, perhaps you'll understand my roundabout sarcasm as I get to the point. But first, the explanation. One photo was of a nice shiny black safe. It was cool but unremarkable. The flash from the camera was reflected on the surface of the safe but hey, it didn't detract too much from the picture. What ya'll missed was that if you paid attention to what else was reflected, well, see above.
Moving on, we have a recent copy of the Army Times with a cover story about snipers and their shifting tactics especially as relating to urban deployment. Inside you have a picture of a sniper in training deployed inside a cinder block building. He is positioned to shoot through a small opening in the wall. The caption explains that the snipers are trained to position themselves far back from the openning to limit their exposure and chances for detection but for safety reasons, the sniper in the picture is set up relatively close to the opening. Here's the riddle. What condition is visible in the picture that makes that really funny? If you figure it out without seeing the picture, I'll be more more impressed. I know you don't care about impressing me but I will be anyway.
