Gearing up for a new season of Jersey Shore (premiering Thursday, January 5), Snooki appeared on The Tonight Show, where she discussed a new addition to the show, The Situation's friend The Unit, and why Vinny quit filming in the middle of the season. Apparently, Vinny was homesick for Staten Island, which Snooki says she can understand because she "wants to leave every day" because she'd rather "relax." Getting fall-down drunk all the time is really hard work, you guys!
