Episode 3 of MTV reality juggernaut Jersey Shore‘s second season last night set new all-time highs for the show: 5.5 million viewers and a 5.3 rating among persons 12-34. They surpassed the previous series high marks posted by the second season premiere 2 weeks ago, which drew 5.3 million viewers and a 5.1 rating in 12-34. This new record probably won’t last long either.
