You know the old childhood rhyme you had to recite (complete with hand gestures) when you were making a serious promise to a friend. But now? You can do it fer reals and emerge with purple or blue eyeballs. Or maybe you just want a super bloody red colour all over. Let EMTs think you're bleeding out or already dead next time you need emergency help after a car wreck.
"If you want to amuse yourself by decorating your eyeball, why not do it?"
Well, kids at home, want to help them out? Why on earth would you not do this?
