If your show comes out on Friday, and your show has a strong history of referencing the 80’s in every way possible, and you just happen to know that a particular episode is going to come out on Friday the 13th, of course, you’re going to take full advantage of that.

Psych, a popular murder mystery show that ran from 2006 to 2014, is just that show. 

Written by Steve Franks and James Roday, Tuesday the 17th is an homage to the Friday the 13th movie series. Shawn and Gus are invited back to their childhood summer camp by an old buddy who’s just bought it. One of his counselors has gone missing, and he doesn’t want to involve the police. So, of course, he calls his old friends who happen to now run a psychic detective agency.

The episode was full of classic slasher motifs. It starts with a blond camp counselor alone being attacked by a knife-wielding maniac in her cabin. It ends with a long, thoughtful stare over the lake. All of the counselors are ridiculously hot, and they make a point of showing them off. And the only one who seems to be the least bit genre-savvy is, of course, Shawn. So when dead bodies start showing up, he does the sensible thing and calls his favorite detective, Juliet. And, unlike most cops on slasher flicks, she’s actually useful. Like, protecting the trail of evidence, keeping civilians safe, actually getting there in time to stop someone from dying sort of useful. This is totally on par for her, but not so much for cops in movies.

The best thing about this episode is the killer twist. About halfway through the episode something changes, a lot of stuff starts to make sense, and the episode goes in a much darker direction. Still funny, but there’s real blood on the floor.

It’s a really fun episode from a really fun show. And if you get a chance, you should check it out. No matter what day of the week it is.
