In an attempt to make the most of its current (and potentially fleeting) ratings gold, MTV is extending the second season of Jersey Shore by adding a pair of specials. After the show’s Miami-set episodes expire October 21, the cast will be corralled for a reunion that will air October 28. The network has also added a “behind-the-scenes special,†which will run on a date to be announced. The series is showing no signs of losing steam ratings-wise: The most recent episode drew 6.5 million viewers, setting an all-time record. Baffling, though, is that this surge is taking place in spite of the increased screen time devoted to the insufferable Ronnie-Sammi “romance.†[HR]
