The Jersey Shore cast is taking a walk down memory lane, a promo clip of the show's Reunion Road Trip: Return To The Jersey Shore, which is set to air on 20 August, reveals.

The video features Sammi "Sweetheart" Giancola, Nicole "Snooki" Polizzi, Mike "The Situation" Sorrentino, Jenni "JWoww" Farley and Pauly reminiscing about hooking up with each other while filming their hit MTV series back in the day.

"Did you get bored with all the ass you got?" Jenni asks the guys. "You get tired of that one night and the multiple womens or the threesomes or the foursomes or whatever," Mike "The Situation" Sorrentino answers.

Pauly "DJ Pauly D" DelVecchio had a question on logistics. "They filmed 24/7 so all the hookups were on tape. I wonder what they do with that footage, I want it."

The conversation gets a bit more raunchy when Snooki makes it personal. "Jenni, would you still f**k Pauly?" she asks loudly.

"Sorry, what?" blurts Farley, who got married to Roger Mathews in 2015 and shares two children — Meilani Alexandra 3, and 15-month old Greyson Valor — with him.

"Rodger would kill Mike," DJ Pauly replies. "Rodger would beat me up."

Later, Farley shoots back at Polizzi, who got married to Jionni LaValle in 2014 and has five-year-old son Lorenzo Dominic and two-year-old daughter Giovanna Marie, with him.

JWoww asks Nicole, "Would you still f**k Mike?"

Hookups and heated confrontations all went to make Jersey Shore a hit when it originally ran on MTV from 2009 to 2012.

The Reunion Road Trip: Return To The Jersey Shore airs on Sunday 9.30pm on E! Network, which will capture the cast sharing nostalgic memories of the past.
