She deserved it. I don't know why some women think they're allowed to resort to violence by slapping men and then expect nothing to come of it.
Women's rights = equal rights. Either everyone can be bitch slapped, or nobody can.
Edit: Oh and just to make this clear, I don't think it's cool to go around hitting women. I'm of the opinion that nobody should be slapped to begin with.
Double edit: And this video is awesome. I've watched the first 15 seconds of this like 20 times now.
