Sammi and Ronnie independently talk to the other roomies and no one sides with Snooki. Sammi decides to take Snooki up on the house meeting.

Again, no one backs Snooki up. Most of all, Mike throws her under the bus.

Snooki decides to apologize to Sammi in front of the house.

Mike brings home a trash bag. What's new?

Snooki also meets someone and he's not a guido.

Vinny hangs out with Danny's girl again. Tanya. They seem to be really getting along.

Mike is nailing his chick in the hot tub. Classy. Just then, Snooki and her non-guido appear and break it up. Mike is unhappy.

In the morning, someone is banging on the front door. Turns out it's Mike's trash bag's friend and he is there to gather her up.

The next night, the house goes out and Ronnie is let off his leash. Not for too long, though.

Mike found it necessary to stress that Ronnie was talking to some chick. Of course, Sammi isn't happy.

Ronnie confronts Mike about telling Sammi about him talking to the chick and denies it. Ronnie doesn't believe him, of course.

Mike's sister returns and she has her sights set on Vinny, who doesn't mind, because he knows the more he drinks, the better she looks (like last week).

It's also a plus that he's annoying Mike by hanging all over his sister.

Suddenly, Tanya appears and Vinny drops Mike's sister for her. That doesn't sit well with Mike.

He decides to confront Vinny, who ends up going back to his sister. Back at home, he decides to make out with her in front of Mike. This does not work.

The house takes a trip to Atlantic City.

At dinner, the guys start laying into each other. Mike then turns his attention to Snooki and she fights back.

But when Snooki asked for a roll, Mike joked about her already having one.

She confesses that she used to have an eating disorder in high school and really takes Mike's fat jokes hard.

At the club later, Snooki gets nuts with some guy. Vinny finds some hot trash bag with fake boobs.

Jenni gets sick in the bathroom and asks Mike to walk her back to the hotel room. He's still with Vinny's ex-trash bag and refuses to walk J-WOWW back to the room.

When Mike comes home, J-WOWW lets him have it.
