The meat pistol is real! The Photoshopping is suspect.
Welcome to Ungood Art Day on JSVB, traditionally the thirteenth day of every month. On this day, I try to show art that I have made that can't qualify as being "good".
I did not on purpose go out to create a gun out of meat, why would anyone do that? When I make my best spaghetti sauce, I use three kinds of ground meat: beef, pork, and veal. The portions I got from the butcher were too big, so I split them. The remainders went into the freezer for later.
When I retrieved them, I had discovered the three meat lumps had frozen into a shape resembling a gun. Knowing I had an opportunity, I took a picture of it and here we are today. I applied some Photoshop to make the picture more dramatic and to make the meat more Magnum-shaped.
