Ronnie, Sammi, Vinny Look Back On 'When I Was 17'

'Jersey Shore' castmembers remember first-time smushing and dodging the cops on latest episode.

The residents of "Jersey Shore" have become pop-culture sensations with their club antics and beach-house brawls. On the latest episode of "When I Was 17," three of the castmembers revealed they've always had penchant for walking on the wild side.

Ronnie broke down the rowdy circumstances surrounding the first time he had sex, which happened with a stranger in the back seat of a Camry.

"It just happened randomly," he said. "[I was] hanging out on the corner with my friend and some girl walks up to him and she's like, 'Your friend's hot. I wanna hook up.' We went to go find a nice quiet spot ... literally down the block."

Ron Ron's friends even watched his very first smush from a car parked behind him and his lady. The beefy Bronx native also explained his back-seat lovin' technique.

"I just pretty much did the head tuck. You tuck your head in between her head and her shoulders and you just like 1, 2, 3, 4. Like three pumps ... and you're done," he said. "It's awesome."

Ron's on-and-off girlfriend Sammi also got into some outdoor shenanigans when she was a teen, choosing the wrong night to swipe her sister's favorite jeans to attend a party that ended up being raided by the police. When she went to make a break for it by hopping a fence, the jeans didn't survive the getaway attempt.

"I go to jump over the fence, and I hear [a ripping noise]," she said. "Literally, my sister's pants split."

But maybe getting busted by the cops would have been less stressful, as her sister chewed her out for destroying her denim.

"She was screaming at me," Sammi said. "We were screaming at each other. Not a good time."

While Ronnie and Sammi were having wild times outdoors, Vinny was bringing the animal kingdom indoors. The Staten Island native copped to keeping an ever-expanding menagerie as a teen, which included snakes, cats, ferrets and more. Vinny was especially attached to an underwater friend who starred in some of the teen's home videos.

"When I was 17, I had a shark, a real-deal shark in a 55-gallon saltwater tank," he revealed. "I was so corny. I would get my webcam, and I used to put the webcam into the tank. I used to play 'Jaws' and feed the shark goldfish, live goldfish, while I was playing 'Jaws.' ... It was pretty cool, nonetheless, not gonna lie."

"When I Was 17" airs Saturdays at 11 a.m. on MTV
