Home is where the heart is. But for the Jersey Shore
crew, it's also the where the fighting, drunkenness and general mayhem are.
Arriving in New Jersey after a season in Italy
, the cast of the MTV show spare little time getting back to their wild and crazy roots, judging by the just-released trailer for season 5, premiering Jan. 5.
Mike "The Situation" Sorrentino and Nicole "Snooki" Polizzi get into a major fight. Vinny Guadagnino announces he's leaving the shore house. And a huge bar brawl erupts in Seaside Heights that leaves Sorrentino bleeding.
The cast come ready with the one-liners, too.
"This is Hurricane Situation and it's headed straight for Snooki Island," Sorrentino says at one point. As she preps for an evening out, Snooki observes: "I look like a Jersey skank, and I love it."
They're all clearly happy to be home. As Sorrentino says: "We're back in our habitat, and I'm ready to tear the speakers off this joint."
