Pretty Little Liars has never claimed to be the most realistic show around. Mysterious murders, omnipotent stalkers, faked death, a town where basically every grown man thinks macking on teens is a-OK... Yeah, Rosewood isn't your average Philly suburb, and that's part of the fun.

Even with that in mind, there are occasionally moments 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 TVs 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 18 (“Hot for Teacher”):

1. Shana is the least helpful friend ever. Shana, we get that you were freaked at the end of the episode, but would it have killed you to let Ali know that Em has her money before destroying your cell and getting the hell out of dodge? It would have taken two seconds.

2. Aria's little discussion with the counselor.  Aria decides she wants to talk to the new counselor about her problems... and then freaks out when the counselor wants to actually, um, know about her problems. Next time, come up with an explanation for why your relationship isn't supported by everyone before you go in, Aria.

3. Emily hiding the money in a coffee bag. Yeah, this actually worked out. But come on. It would have been so easy for that money to go missing.

4. Hanna's trip to Ravenswood. OK, this is more of a crossover logic fail, but we are really confused about when Hanna's little trip to Ravenswood is supposed to have taken place in relationship to Pretty Little Liars. And also why her hair apparently got longer on the drive over.

 Did you pick up on any logic fails this week? Let us know in the comments below!
