I saw the 'Taboo' tv programme about the guy who tattooed his eyeballs light blue. Kinda funky looking, but he should have used a less faggoty colour if you ask me.
On that prison show Lockup, there was a couple guys who tatted their eyes blue and red. That shit looked fuckin crazy.
I don't know how they can sit there and not want to move their eye around. And what do you have to do, go to an eye doctor and tell them you want this? You sure as hell can't it it from a parlor.
