Hey kids, we know you're down with some "health-hop," so check out this fresh new video from the Rappin' LIRR Doctor John Clarke. You may remember the Notorious DOC from such health-hop hits as the award-winning H1N1 Flu Rap, and... well, that's it. But here to prove he's not just a one hit wonder, he's back to drop some mad gucci "gapsta rap" about the dangers of the LIRR gap.

LIRR President Helena Williams tells the Post she's hopeful this "unique" YouTube video will "reach a wide audience." But when you've got ill beats and fresh rhymes like Dr. Clarke, who needs hope? For his next hardcore joint, he just needs to lay down some knowledge about the health risks associated with flashing a piece to shut up rowdy Rangers fans on the train.
