On 'Jersey Shore' (Thu., 10PM ET on MTV), Vinny says he keeps his mouth shut. And then he doesn't -- instead telling Jenni "JWoww" Farley that Angelina "Jolie" Pivarnick told a lie about her.
Jenni confronts Angelina and Sammi "Sweetheart" Giancola, who says she "doesn't give a [beep]." Jenni says, "Did you grow some balls all of a sudden?" Sammi responds: "I don't fight because I'm mature, I'm classy!" and then proceeds to scream and shout at her.
Jenni yells back, "Why don't you like me -- because I came to you as a woman and told you about your man?" -- referring to the anonymous note that told Sammi about Ronnie's cheating ways. Jenni shoves Sammi's head. Arms start flailing, and Sammi throws a punch.
