Drawing on one's self is a nasty habit, but it's awesome to look at.
And unlike most of us (or at least me..) you can actually draw really cool looking things!!
Oh, and yeah, I wouldn't recommend white-out on your hair, but sharpies are actually really cool. It obviously shows up better on people with lighter hair, but mine is really dark red, and you can see it fine. When blue catches the sunlight, it looks amazing!
