There will be a much longer in-depth analysis of tonight's episode of Jersey Shore (which is not over yet) - just thought that there should be an image out there of what just happened. Sammi just punched Ronny in the face because she found out he's friends with JWOWW. Jenni was saying that she told Sammi about Ronny cheating and did the note so that Sammi would leave, not to be a good friend. Snooki's intentions were not that way.
Don't worry, Sammi comes to her senses.
