Multiple times? C'mon, in THIS economy, they surely could find another principal, that, y'know DOESN'T hypnotize students. And if it's multiple times surely some parents have heard about this by now. How the hell have they NOT run him out of town?
I mean, I know there is some positive stuff that can happen with hypnotism, but I would find it a bit icky if I learned my daughter's principal was hypnotizing her.
