I debated for a while whether or not I should post this picture. I keep things PG-13 here, and I don't find the picture of a smooth butt with pac man buddies tattooed all over it as being offensive, but then again, the site I pulled it from originally listed it as NSFW, so I wasn't sure.
When it comes down to it, though, it's just a butt! And you should be looking at the Pacman tattoo, not the crack anyway. ;)
Gizmodo also has a video of a Pacman jacket that flashes graphics across the front. It looks insanely uncomfortable, but it has moving Pacman guys, so it's probably worth it.
