Jersey Shore

Ronnie entered his plea in Ocean County Criminal Court ... where he was arraigned for allegedly punching Stephen Izzo back in September of 2009.

On an episode of 'JS' Ronnie bragged he knocked him out with "one shot."

A rep from Rosetta Stone tells TMZ, they sent their Italian language program to several members of the "Jersey Shore" cast -- and according to a source close to the show ... Ronnie and Pauly have already made impressive progress with the program.

In fact, Ronnie even talked about his progress on Friday's TMZ Live.

Sammi issued the mea culpa last night in NYC with "Jersey" co-star Deena -- telling us, "Violence is not the answer."

According to the realtor's website, the three-bedroom house -- located in East Setauket, NY -- is a short walk to the beach on Long Island ... but here's something the dynamic duo may have to get used to ... it doesn't come with a pool.

TMZ ran into "Sopranos" star Joseph Gannascoli at Vincent's Restaurant in New York yesterday -- where he admitted that his show "paved the way" for Snooki & company ... who also play Italian stereotypes on TV.

And in a horrible twist of fate ... Jwoww and her reality show crew also showed up to the restaurant.

It's just another one of the jewels we discovered in the rundown of Snooks' new show -- "Snooki and Jwoww Vs. The World" ... yes, that's the actual working title.

According to the documents, obtained by TMZ, one of the big scenes takes place inside of a Jersey bank, when Papa Snooki tries to teach the 23-year-old how to fill out a check book.

When Snooki ... who's reportedly banking $30k per ep ... finally opens her first checking account -- she asks the banker, "Do you have any blinged out checks?"

The rundown explains, "She gets a crash course in balancing her checkbook ... but adding and subtracting from the ledger proves too much for her."

Shocker.

It was a pretty shocking promo for this week's episode -- Sammi slugs Ronnie across the jaw during an argument ... an act of violence nearly identical to the thrashing Amber Portwood unleashed on her baby daddy just a few months ago ... the same thrashing that landed her behind bars.

As we previously reported, Amber was charged with felony domestic violence over the on-air beatdown -- but according to the Chief of Seaside Police, Sammi won't be prosecuted whatsoever ... at least until Ronnie decides to press charges.

We got our grubby little mitts on the rundown for the upcoming Snooki and Jwoww spinoff show -- and according to the docs, there's gonna be a whole lotta boozing and she-pimpin'.

The storyline -- Snooks is finally moving out of her parents' house and into a place with Jwoww -- but, (surprise!!!) she's totally unprepared to deal with actual real-life problems.

For example ... the two have their sights set on a $1.5 million pad, but they don't know what a mortgage is ... or how to write a check ... and they keep getting distracted by the "hot" mortgage broker.

But conflict erupts -- so say the docs -- because during their cohabitation, Snooki ... gasp ... "made a mess of the bathroom and didn't change the toilet paper." She also "ate a ton of Jwoww's food" ... and anyone who's ever had a roommate knows that crap don't fly.

So what will happen??? We're guessing a ton of cussing and drunken debauchery ... can't wait!!!

TMZ spoke to a rep for UNICO -- a massive Italian American interest group -- who tells us they're furious with MTV's decision to shoot Season 4 in the old country ... saying, "People used to go to the circus to see the freak show – that is what this will be."

The rep adds, "It will not only hurt Italians but all Americans … their outrageous, reprehensible behavior will make us look like buffoons and bimbos."

Sources connected to the show tell us they will be scouting locations in Italy -- similar to the way they did it in Miami -- to find the right locale.

One source connected with the show says they've already lined up some of Vinny's Italian relatives to host the "Jersey" crew for an authentic Guadagnino dinner.

And we're told ... two months ago execs began working on getting visas for the cast and crew.

Of course, the whole thing is contingent on whether the Italian government lets them in the country!!

Snooks shot scenes for her new show at her parents' house in Marlborough, NY. In the clip, she's riding in a Marlborough Fire Department car with her dad -- who's a fireman -- as they pull into the home and walk inside.

This time it's a 2011 Jeep Wrangler Sahara -- two of 'em, actually ... one for himself and one for his brother Marc. The cars were purchased through the boys' company MPS Entertainment and we're told Unique Autosports Miami did the customization -- which included brand new leather interiors, a sound system complete with subwoofers, and 22" rims. Total value ... about $75,000 each.

According to our source, The Sitch was inspired by Diddy who recently got a Jeep just like it.
