After five painfully long seasons, 'Jersey Shore' will begin its sixth and final season this fall. Maybe it's because Snooki had a baby and things are starting to get real. Maybe it's because the ratings have started dropping and show no signs of stopping. Or maybe it's because this show is terrible. Regardless, we thought we'd pay tribute by reminding you of some of the terrible commercials the show's "stars" have done over the years. No matter if the subject is safe sex or diet pills, they are all awful.
