I part-timed in a local tattoo shop a few years ago. For some reason we couldn't figure out, an entire order of ink had GCN logo stickers on the underside of each bottle. We called the company, but they didn't have any idea what we were talking about.

Outside of that, at that same shop, I saw a chick who had the N64 logo as a tramp stamp and a guy who wanted the PSX logo tattooed on his joystick.
