It's a silly question, to be sure. But when you think about it, isn't there a little Barbarian in all of us? How you answer this is up to you.
As for myself, I'd say Necromancer. I work with younger kids, and it's always fun getting them running around doing my bidding, like an army of little skellies. That, and I curse quite a bit. But not at the kids, of course.
