re: Serious question: how did Ole Miss get known for having the finest girls in the SEC?

IMO it's their emphasis on greek life (specifically sororities in this case) and legacies. It brings in hoards of girls who are legacies going for that elementary education degree with a concentration in husband hunting. Those types tend to focus a hell of a lot more on looks than substance.

ETA: Not that doesn't happen at other Southern colleges, it just seems to be far more highly concentrated at Ole Miss.
