Check this out, folks. These guys are 2 examples of the latest frontier in body modification- eyeball tattooing . I shit you not. These cats did it in prison, but I've seen video of the process and it looks horrifying. You don't use a gun, but something that looks kind of like the needle one uses to truss a roast. There'a another method involving a hypodermic needle. They not only ink the fronts of the whites, but roll their eyes back and ink that.
The first dude known to do this was a few years ago in Toronto, and it was a creepy thing to see. I have been pierced in places that would freak out a lot of folks, but this is so over and beyond the scope of my imagination. I'm not sure whether to be impressed or horrified.
The video below is a slideshow that includes several of these unusual tattoos.
