'Jersey Shore' Tea-Shirt Time: Snooki Fears Vinny Will 'Ruin' Her Marriage, JWoww Reveals Miscarriage and Ronnie's Still Not Over Sammi
'Jersey Shore' Stars: How They've Changed Since Season 1

Mike "The Situation" Sorrentino also details the drug and alcohol withdrawal he was experiencing while filming Season 4 in Italy.

On Thursday's "Jersey Shore: Family Vacation," Mike "The Situation" Sorrentino opens up to Jenni "JWoww" Farley about his erratic behavior in Italy (Remember when he head-butted a concrete wall?), but it turns out he wasn't the only one going through a rough patch at the time.

During a one-on-one conversation the night after the group miraculously found Nicole "Snooki" Polizzi's wedding ring in the backyard, Jenni asked Mike what made him decide to turn his life around. Mike is currently 2 years clean and sober.

Mike told her he had attempted to get sober by himself right before the cast filmed Season 4 in Italy, but that he continued to smoke weed and cigarettes.

"I just realized that my way wasn't working," he said. "I had to realize that my personality was an obsessive personality with everything I did, anything I did -- and I need to have a handle on myself."

That's when Jenni told Mike that she, too, was "a mess" in Italy.

"Right before Italy -- it was like 3 or 4 weeks before Italy -- my grandmother passed, and me and Roger [Mathews] actually lost a baby, like, I ended up pregnant," she said. "Not a lot of people know, and they put me on medication because of it because I couldn't handle life. But the medication was like Xanax to like take me down, but the downers were making me so groggy. Then I started taking uppers. Segue right into Italy. Like, I was a f-cking mess."

Mike also told Jenni that the majority of the explosive fights he had with Ronnie Ortiz-Magro while in Italy were a result of him withdrawing from drugs and alcohol.

Later that day, Jersey's finest decided to take a whack at rock climbing. A bunch of guidos/guidettes rock climbing...what could go wrong? Snooki and Deena Cortese ended up racing to the top, and Snooki lost, which meant she was stuck cleaning the actual shitstorm Ronnie left in the bathroom before they left for rock climbing. By the look on Snooki's face and the fact that she described the crime scene as "diarrhea soup," she did not enjoy herself. In fact, her efforts went to waste (Get it?) because they ended up calling a plumber anyway.

Then Ronnie's pregnant girlfriend (she's since given birth) called, and it was the most painfully awkward conversation that duck phone has ever seen. They talked about nothing, and there were lots of awkward pauses. BUT WAIT, because after he hung up, Ronnie looked at Sammi Sweetheart's doll and said, "That's what a normal relationship's like, Sam!"

Pauly D, who witnessed the whole thing, later told cameras, "Ronnie may possibly be in denial. He happens to always bring up Sammi, no matter what it is that we do. He's still in love I think. It's bad."

Bad it is -- because later on when the gang went out for Sunday Funday, Ronnie decided to get "Who wrote the note?" spray-painted onto his chest. Awkward. But not as awkward as Vinny Guadagnino insisting he and Snooki move passed the fact that she was once in love with him and that they've hooked up before and that Snooki didn't invite him to her wedding. She's too married for you, bro.

But that didn't stop Vinny! The "Keto Guido" ended up wasted at Sunday Funday and kept twerking on Nicole, which prompted her to run away yelling, "No! No! No! Respect my marriage! That's not allowed! We're friends, but we're not friends like that." She does have a point.

Later on -- in a more civilized, calmer setting -- Vinny tried to ask Nicole what the boundaries were for their relationship, which set her off.

"You're gonna ruin my marriage!" she yelled back multiple times. "I just know that my husband hates this! I don't want to disrespect my husband!"

When Jenni tried to talk to Snooki, Snooki lost her shit all over again and called Jenni a "f-cking idiot" and a "bad friend."

"Own your shit, Nicole," Jenni yelled back. "Say to him, 'I f-cked up with you, so I can't be around you. Simple. Being an adult!"

Snooki did hook up with Vinny in Italy while she was dating her now-husband, Jionni LaValle, so maybe she should stay away from Vinny? Sound off in the comments below.
