I dunno. This guy at least has a purpose for his facial tatoos and other bizarre body modifications. There's some kind of weird tribal symbolism there, and I can respect that.
When I was in college there was a girl who came into the computer labs I worked in who had, among other things, tatoos on her eyelids (owwww) and throat, multiple solid-bar piercings through her breasts, earlobes with holes so distended you could stick a golf ball through them, and probably two-dozen facial piercings.
She was an elementary ed major.
Would you want someone like that teaching YOUR seven-year-old?
