The cast's use of the derogatory term "zoo creatures" is ironic because they act like animals—struggling with basic things like telephones, impulse control, and logic. But we're not watching for their thoughts on politics. Or are we?
Jersey Shore is actually the epitome of reality television in that it entertains us on a really base level (like seeing Snooki drunkenly flash her thong while she thinks she's winning at a fight that nobody is even taking seriously), while also providing many of us with an opportunity to observe the behaviors, choices, and musings of a group of people with whom we'd otherwise probably never get to know. It really is like observing primates at the zoo or lab rats in a science experiment, as we watch what they do and try to understand why they do it.
Case in point: The slut-shaming of Angelina that revealed their thoughts on sexual double standards. (The "thoughts" being that sexual double standards exist, and that's just the way it is.) The roommates seemed to have a lot of reasons not to like Angelina—she was messy, inconsiderate, and started shit for the hell of it—so it's was a little weird that they took such an interest in judging her for her sexual activities, when Snooki exhibited the same kind of behavior as Angelina, and often times, with the same guys. In fact, the female roommates seem to treat men like trading cards. So their understanding of sexual double standards is, well, a little hard to understand.
