In honor of today being Halloween and all, we thought we'd take a quick look back at two of the Hills stars' most memorable costumes. And since we already showed you Lauren's flapper girl getup, we figured we'd give Audrina, Brody and Frankie a chance to get all nostalgic and relive the amazingness of their Madonna and Batman & Robin days. One question, though: Just how in the hell did Frankie convince Brody to be HIS superhero sidekick??
