10. Pauly D and Deena on Jersey Shore (2011)
Though we’re pretty sure that each of the Jersey Shore cast members have hooked up with one another at some point, there’s a difference between innocently assuming it and actually seeing it. In the premiere of this year's lackluster fourth season, set in Italy, we get an eyeful of Deena coming onto Pauly D in a club, followed almost immediately by unmistakable tongue wrestling. All we can really say about their "kiss" is that it can’t even be called kissing—it’s just too grotesque. Watch it and see if your expression doesn’t resemble Ronnie’s by the time the scene ends.
