When a show has been on the air for 15 years, chances are high there are a few weird episodes plugged in somewhere. With a show like Supernatural - which reveled in pushing the envelope with odd and often meta episodes - there are more than just a couple.
From playing themselves acting in the show Supernatural, to suffering through a Groundhog Day, and even getting animated and teaming up with Scooby-Doo, these are the strangest cases Sam and Dean ever worked.
The French Mistake
Season 6, Episode 15
The show's most meta episode by a mile (which is saying something coming from a series like Supernatural) is "The French Mistake." In order to lose the angels and demons that are looking for them, Sam and Dean are pushed into another universe where Supernatural is a minimally viewed but passionately loved series, and the two play themselves - Jared Padalecki and Jensen Ackles - who are the actors on the show.
The episode pokes fun at Ackles's previous acting gigs on soap operas and the fact that Padalecki married Genevieve Cortese - who played the demon Ruby in Season 4 - in real life.1201So weird it's good?
Season 3, Episode 11
Any show that's been on the air as long as Supernatural has to do an obligatory Groundhog Day episode, and that's "Mystery Spot."
Another one of the Trickster's ploys, Sam is forced to watch Dean perish over and over again as he relives the same day and fails to save his brother time and again. The Trickster wants to show Sam that no matter what he does, he won't be able to stop Dean from going to hell at the end of the year.
It's a weird episode with a surprisingly dark message - right where the show butters its bread - that'll also manage to get Asia's "Heat of the Moment" stuck in your head.1048So weird it's good?
Season 4, Episode 6
Dean gets infected with a ghost sickness that makes him increasingly more afraid of everything around him. He begins by questioning why he and his brother hunt monsters, and if they might be nuts, then refuses to stay at any hotel that isn't on the first floor because he's afraid of heights. As the episode progresses, he refuses to use a firearm and screams at the top of his lungs when a cat scares him in a warehouse.
The episode also features the song "Eye of the Tiger," and to get full use of their money, there's a stinger after the episode of Jensen Ackles lipsyncing the song while the cast and crew laugh.975So weird it's good?
Season 10, Episode 5
The show's 200th episode is a meta celebration for the fans. Sam and Dean stumble across a case very close to home when they head to an all-girl school putting on their own musical adaptation of the Supernatural story. There are tons of nods to the real show's fandom - including shippers' love for pairing off Dean and Castiel (Destiel), and the more uncomfortable Wincest (Winchester incest) shippers.
It also includes a number of original musical numbers like "The Road So Far" and "A Single Man Tear," as well as a cover of Kansas' "Carry On Wayward Son" - the song that plays before every season finale.10210So weird it's good?
