Busted! On 'Jersey Shore' (Thu., 10PM ET on MTV), Sammi "Sweetheart" Giancola finds an anonymous note on her bed. It says that Ronnie Ortiz-Magro "gets with fat chicks, hooks up with girls, holds hands with girls, got a girls number," Sammi says.

She immediately shows it to Vinny, who feigns ignorance and swears secrecy. But he swiftly warns Ronnie about the letter. Reading it, Ronnie notes the use of the word "wisely" -- "Snooki doesn't use that kind of vocabulary." Regardless, what does Sammi think about its message?

When she asks Ronnie whether he made out with anyone at the club, he says he can't remember. Then he says, "I don't think so, no." Cut to clips of him making out with two girls at once. Thankfully, Sammi doesn't believe him.
