Rosewood isn't exactly a normal world, what with the all murder, stalkers, and big bad secrets. It's a heightened universe, and that's part of the fun. Even with that in mind, there are occasionally moments on Pretty Little Liars that make us stop and say, "Really?" Sometimes it's something that doesn't make sense from the writers, and, more often, it's just that we want to reach through our TV and smack the characters upside the head for making bad choices.

Here are our picks of the biggest logic fails and most WTF moments from Season 4, Episode 8: "The Guilty Girl's Handbook."

Aria doesn't know Mike is taking martial arts classes. OK, this isn't totally out of the realm of possibility, but given how closely Aria has been keeping tabs on her little bro, it seems mildly implausible that she had no idea he was taking martial arts classes. Seriously, does no one in the Montgomery family ever talk to each other about their lives?

Ezra, the college guidance counselor? Ezra's an English teacher, not a guidance counselor. It makes sense that he would help the Liars out on their college essays, but why is he randomly advising Emily about schools to apply to? We're pretty sure any high school the Hastings would send their daughters to would have a pretty solid guidance program without having to involve recently hired English teachers.

Toby heads off to New York to knock on doors. By himself. Because he has learned nothing about confronting the "A" team, apparently. We hope he doesn't run into trouble!
