We know, we know. Stop trying to make "fetch" happen. On the eve of the "Mean Girls" 10-year anniversary, it's only appropriate to look back at the best villain of all time (not hyperbole, just fact), Regina George. The high school brat who ruined five teachers' lives, wore a tank top with cut-out boobs and created the burn book will forever be in our hearts as not just a mean girl, but the meanest girl. Watch Regina's best insults from "Mean Girls." Then look both ways before crossing the street.
