It's no secret that "Jersey Shore" star Mike Sorrentino has come a long way since first appearing on the hit MTV show, but that didn't stop his fellow co-stars from reminiscing about the good ole days.

On Thursday's episode of "Jersey Shore: Family Vacation," the guys -- Vinny Guadagnino, Pauly “DJ Pauly D” DelVecchio, and Ronnie Ortiz-Magro -- start to write their speeches for Mike's upcoming wedding to his college sweetheart Lauren Pesce.

“We want to keep it all positive,” Vinny says in the sneak peek.

“The thing about this is we joke around with each other, but now it’s in front of his family, in front of her family,” Pauly adds. “So we have to sort of censor our jokes a little bit.”

“Mike was a savage. Mike started off as ‘The Situation,’ a complete d-bag,” Vinny explains. “It’s so hard to think of him like that — ‘The Situation.’... Mike was mean, he was arrogant, double-crossing people, manipulative.”

“Who would have ever thought that my grenade whistle would ward off all the grenades and brought him to the right one?” Pauly jokes. “Mike owes me a favor. Lauren took ‘The Situation’ out the game!”

Now, at 37-years-old "The Situation" is a married man and nothing like his younger self. He is currently finishing up an eight-month prison sentence for tax evasion but there's no doubt that he will continue this streak after his release.

"Jersey Shore: Family Vacation" airs Thursdays at 8 p.m. ET on MTV.
