'Jersey Shore,' Season 4, Episode 7, 'Meatball Mashup': TV Recap. This is a Deena/Snooki episode. The meatballs get sauced and then they get steamy and then they crash into a police car. The episode starts with a "reality check" from Jenni and Ronnie to Snooki regarding Jionni. She just wants them to shut up. Tanning and sleeping and drinking must have messed up Snooki's short-term memory cuz Jionni was being a real jerk last episode (or last night in filming-time).
