Back at the house, the sober crew returns with vengeance in mind. For some reason, they decide to go to the refrigerator, where they zero in on both grated and cream cheese. They smear and sprinkle the dairy goodness on Sitch's bed, confident in the fact that he will never discover it, since he never washes his sheets. They happily pile into the confessional to gloat about their prank and cheer for Team Sober.

Back at the bar, Pauly and Sitch invite their smash buddies home, where Sammi and Snooki mock their grenade-like choices and laugh the minute that Sitch heads upstairs to get it on atop a bed of parmigiano. Snooki worries that he and his trick might both get pinkeye, but Sammi thinks it would be well-deserved.

A couple days later, Deena, Snooki and JWOWW are bitching about how smelly their porch is when Sitch comes out all, "Speaking of odors..." He tells them about his trick from the other night and how she smelled like grated cheese. He says he even let her keep his clothes because of her hobo-like aroma. Snooki plays along, claiming that's disgusting, then runs to Sammi the first chance she gets to report that their mission was a success. Snooki says Sitch is a sucker, and that it's the best prank in Jersey Shore history.

A few minutes later, Sitch follows them upstairs to tell them how he booted his trick out the minute he got head, then sprayed his bed down with Axe. Of course he did. JWOWW tells him that he probably got an STD from the oral sex, and Sitch seems blown away that that's even an option. Hello, Herpes Simplex B? This is confirmed by a call to the local medical clinic. Good thing they hand out Valtrex like candy at this joint. The doctor also confirms that the grated cheese odor that supposedly emanated from this girl could indicate a yeast infection. Everyone groans and ewwwwwws like third graders. Says JWOWW, "It won't be long before Mike's dick falls off." Sitch thinks it's all good because he just got head and didn't even make out with the girl (who is this person?). JWOWW jokes that he'll probably have some yeast in him. Cue another round of "Ewwwwww!" as Sitch fist pumps proudly.
