Ever seen this photo on Tumblr? An Italian newspaper just published the story behind it...
It turns out that Cardinal Jozef Glemp of Poland was visiting the Cold War Museum in Virginia. So they gave him a Dragunov SVD sniper rifle (confiscated from the Russian mafia) to hold and somebody thought it would be funny to take a picture. No more story to it than that.
If you're going to take it and put a caption on it, I suggest "Don't Quit Your Day Job, Eminence"...
