Top 10 Unscripted Supernatural Moments That Were Kept in the Show

Before getting those oh-so-fashionable tattoos, the Winchester boys have to worry about being possessed by demons. One of their most frequently encountered demonic foes is Meg, and she possesses Sam in this episode. Although Bobby and Dean are able to capture Meg, she breaks out and beats Dean up. Fortunately, Bobby manages to expel the demon. As Sam reels from the experience - which he can’t remember - Dean punches his brother in the face. Originally, the scene was meant to end on Sam’s bewildered amnesia. Dean’s actor Jensen Ackles improvised the punch, which only made Sam’s confusion even funnier.

While investigating a banshee terrorizing a retirement home, Sam and Dean encounter Eileen Leahy, a deaf hunter out for revenge on the banshee after it killed her parents. She and Sam have a fun connection throughout the episode and thereafter. When they first meet though, Eileen makes a sign to Sam saying “thanks,” and Sam seemingly responds in kind. However, the sign is actually the one for the F-word! Actors Shoshannah Stern and Jared Padelecki came up with the joke together. It’s no wonder folks started shipping them considering this was part of their first interaction!

On an apocalyptic version of Earth where the Winchesters were never born, angels and demons battle it out on a world with humans caught in the middle. This world’s version of Charlie Bradbury is being unsuccessfully tortured by angels, when her tormentors call in a specialist: Castiel. However, this version of Castiel is notably different, seemingly blind in one eye, having a facial tic, and wearing a different coat. Oh, and he also has a German accent. The last of these was not in the script, and actor Misha Collins came up with it after seeing his wardrobe. Collins apparently regrets the choice now, though it’s certainly memorable.

While we’re on the subject of Castiel, everyone’s favorite angel joins Sam, Dean, and Bobby when they investigate a town in Oregon where Eve, the mother of monsters, has set up shop. However, upon arrival, Cas has trouble using his usual angel teleportation. When Dean uses a colorful metaphor for Castiel’s impotence and insults his usefulness without his powers, the angel simply turns and looks away. Reportedly, Misha Collins actually forgot what his original line was, leading Jared Padalecki to improvise Sam’s observation that Dean may have hurt Cas’s feelings. Well, guess some mistakes work out for the better!

While investigating a mysterious death involving stigmata wounds, Sam and Dean are pointed towards a religious family who lives off the beaten path. While walking up the drive, the brothers discuss their recently returned, and then departed, mother. However, their entrance to said drive sees Dean attempt to hop the fence by awkwardly shimmying over it, while Sam goes around with little effort. It’s a small, funny bit of character interaction that was not in the script, but invented on-set. It certainly feels like a typical sibling moment for the Winchesters.

While this episode primarily focuses on side characters attempting to save the Winchesters, the boys do feature in it as well. Trapped in an alternate universe inhabited by giant monsters, Sam and Dean are forced to make do with what they can find to survive – which means eating lizards. Dean seems more willing to indulge in eating the local fauna, and when one of the larger monsters starts to sound closer and closer, the duo hurries off. However, Dean goes back for the cooked lizard after initially leaving it behind. Jensen Ackles improvised the moment, as he reasoned that Dean would never leave food behind – even lizard on a stick!

This hilarious “X-Files” style episode sees the Winchesters looking into crop circles. But, instead of aliens, the true culprits appear to be fairies. Unfortunately for Dean - but not for us - he accidentally attacks a little person after mistaking the man for a fairy. Although his hilarious excuse that he was “just kidding,” was also an improvisation by Ackles, our pick goes to a moment a little bit later. Naturally, Dean is arrested for assaulting the man and as he’s being put in the police car, he yells to Sam: ["You fight those fairies"]. Although this off-the-cuff line by Dean is funny in-context, just imagining what all the bystanders think makes it even more so!

As any “Supernatural” fan knows, Dean’s favorite exclamation involves mentioning the male child of a female dog. The amount of times Dean uses the expression leads to it essentially becoming his catchphrase. Although many of the times Dean says it are in fact scripted, Jensen Ackles occasionally included the expletive when it wasn’t written in previously, as a result of how in-character he gets. One memorable instance is at the conclusion of the season 3 episode “Bad Day at Black Rock.” After discovering that Bela Talbot has stolen his winning lottery tickets, Dean is left stunned. Dean’s outburst wasn’t scripted, and you can see Jared Padalecki trying not to laugh. We’re right there with him!

We still can’t believe this episode is real! Sam, Dean, and Castiel get sucked into TV land, specifically the animated world of “Scooby-Doo.” While there, they encounter an all too real ghost, which clashes hilariously and traumatically with the Scooby gang’s usual antics foiling old people in masks. The gang…doesn’t take it well. However, thanks to a pep talk from Dean, they regain their confidence. Dean also claims that they can help out by doing what they do best – making a trap. Although most of the speech was scripted, Dean’s use of the F-word for emphasis was an invention of Jensen Ackles in the recording booth. Jinkies!

Before we get to our top pick, here are a few honorable mentions:

Grenade Launcher, “The One You've Been Waiting For”
The Whole Exchange Between Sam & Dean Over the Weapon Was Unscripted

4th Wall Break, “Fan Fiction”
Dean Looking at the Camera When Destiel Is Mentioned Was All Ackles!

Slap, “Last Call”
The Two Actors Improvised the Bit with the Butt Slap

The Scent of Dean, “In the Beginning”
Possessed Samuel Sniffing Dean Was Mitch Pileggi’s Creepy, Creepy Idea

Bunny Buddy, “Regarding Dean”
Jensen Decided for Dean to Pick Up & Pet The Wayward Wabbit

You probably saw this coming. During the episode“Yellow Fever”, Dean is cursed with fear at nearly everything. To give himself courage in one scene, he lies down in the Impala and listens to “Eye of the Tiger” while air drumming. Although the scene in the episode proper stops shortly thereafter, Jensen Ackles continues his performance of the song in a now famous outtake aired after the episode, lip syncing to the lyrics and using his leg to “play guitar.” It’s such a funny and surprising moment and it’s all thanks to Ackles just screwing around on-set and the director leaving the camera rolling.
