Supernatural: 10 Biggest Fan-Service Moments

When it comes to crazy metafictional episodes, it simply doesn't get any better than this. The French Mistake doesn't just break the fourth wall, it demolishes it with a bulldozer, and fans loved every second of it.

The iconic Season Six episode sees Sam and Dean transported from their world to ours. Well, not ours exactly, but close enough to it. It's a parallel universe where Supernatural is a TV show and the Winchesters are played by a couple of oddly named actors - Jensen Ackles and Jared Padalecki.

Naturally, this episode is packed to the brim with self-referential humour and satirical jabs at the cast, and the show as a whole. Whether it be making fun of Jensen's soap opera past or Jared's marriage to Ruby (a.k.a. Genevieve Padalecki), this episode doesn't shy away from self-deprecating humour.

This episode is universally adored for the way that it not only shines a light on what goes on behind the scenes, but openly mocks itself in a fun and good-natured way. The Supernatural fandom has grown just as attached to the show's actors, as the characters they portray and this episode provides a rare opportunity to give them a serving of both (Misha tweeting to his "Mishamigos", anyone?).

It's a fun and clever story that proves that the show never took itself too seriously, and was happy to mock itself in order to make the audience laugh. It truly is one of the greatest gifts the show ever gave to its fans.
