TRENTON, N.J. (AP) — T won't stand for tax-credit in MTV's "Jersey Shore" GTL motto.Gov. Chris Christie has blocked a $420,000 film credit that was approved for the show last week by the state Economic Development Authority.The money was approved to cover production costs for the hit reality series' inaugural 2009 season.Christie suspended the film tax credit program in 2010 to close a budget deficit, but the 2009 season still qualified.Christie says he "duty-bound" to ensure taxpayers are not footing a bill for a project that "does nothing more than perpetuate misconceptions about the state and its citizens."The show centers on the cast living and partying along the beach and boardwalk in Seaside Heights, where they live the so-called "GTL" lifestyle — or gym, tan and laundry.
