Is The Situation obsessed with Vinny? Vinny thinks so. Or does he just want his girl Ramona? While Vinny's in the bathroom at a club, The Situation (Mike Sorrentino) "pulls a little of the robbery" (says Pauly D) on Ramona, flirting with her and dissing her man.

"I'm worried," says Vinny on 'Jersey Shore' (Thu., 10PM ET on MTV). "He's always hooking up with the same girls I'm hooking up with -- happened in Jersey. It's happening out here. Mike might have a secret possible obsession with me."

But Ramona rebuffs Mike, and he scowls in a corner, glaring at the dancing couple and throwing his cocktail straw in frustration. He then approaches Snooki for some physical attention. That goes... badly.
