With talented actors who know their characters as well as the leads on Supernatural, it's no surprise that occasionally unscripted dialogue makes it's way into the episode. While we will never know all occasions when this has occurred, many instances have been related during interviews and Convention panels. Others don't make it to screen but end up in the gag reel.
“Most of the improvising that we do is slapstick, jackass tomfoolery, so it’s pretty much just for the outtake reel,” [Jensen] Ackles reveals. “The writers know us, and they know how we speak, so we don’t have to do a whole lot of improvising or a lot of paraphrasing. They write for us because they know how we would say certain things and how we would respond in certain situations, so we’ve been fortunate enough to be able to stick to the script and sound and feel normal and correct. But we do throw in little things here and there, and if it’s something big, we’ll call up Eric [Kripke] and be like, ‘Hey, dude, for me, this just sounds better. What do you think?’ He’ll usually say, ‘Yeah, man, if you’re feeling it, then just go with it.’”

Eric Kripke: “Yes. But I generally dig the ad-libbing. The boys [Jensen Ackles and Jared Padalecki] are awesome at ad-libs. But the director who is the heavyweight champ of ad-libs is Sgriccia. He directed "Nightshifter", "Hollywood Babylon" and "The Kids Are Alright.". Now he’s directing "Ghostfacers." To give you an example, he’s got great instincts and he’ll let them ad-lib and do something hilarious and all these little moments that aren’t scripted, and then also shoots it straight. But 8 out of 10 times we’ll use the ad-lib. Because I don’t give a sh#& where the good idea comes from, as long as it’s funny. It makes ME look good, so why not! You’re going to really like "Ghostfacers" because it’s like Spinal Tap. We’re watching the dailies and there is so much ad-libbing. Harry and Ed, the Hellhounds from Season 1 are back. And everyone is just so funny! We’re going to be using a bunch of dialogue that they just came up with on set.

After Meg is exorcised form Sam and he comes to, Jensen improvised the punch Dean gives him.
Jensen ad-libbed Dean's line to Sam: "You stink like sex!"
Director Philip Sgriccia (who was also the show's post-production director and producer of each season's gag reel) kept the cameras rolling as Jensen spontaneously launched into a roof top performance of Eye of the Tiger.
When Sam is being inhabited by Gary, the scripted line was "I would love to have sex with you Crystal" and Jared changed it to "Crystal I would love to have the sex with you." From Supernatural: The Official Companion Season 4 (pg 65).
Dean: Well, that's great, because without your power, you're basically just a baby in a trench coat.
- Castiel does not respond, and looks out the window.
Sam: I think you hurt his feelings.
- In this scene, Misha reportedly forgot his line in response to Dean, so Jared added I think you hurt his feelings.
- When Sam and Dean are visiting the psychic Marion, Jared ad-libbed the line "You have bigger cups?"
- When Dean realizes the little person he has tackled is not a fairy he added, "I’m just kidding!"
- When, after a prolonged fight with the Leprechaun, Sam belatedly pulls a salt shaker from his pocket Jared added "Why didn’t I do that earlier?"
- Jensen added the line "You fight those fairies" after "Fight the fairies."
Per the episode commentary with director Phil Sgriccia and writer Ben Edlund, Dean's awkwardness around Aaron Bass during their initial meeting was not scripted, and was Jensen's choice to play it, "Right down the middle. You know, just more awkward about it." Dean slowly dragging his FBI badge across the table was also an improvisation on Jensen's part that was just caught on camera.
- Jensen tweeted about one improvised moment "Hey all you "FanFic" writers out there...that look into the camera wasn't scripted. Just sayin. #WinkWink #Supernatural200thEpisode" He's referring the fourth wall breaking look Jensen gives after Destiel is mentioned.
- The "Andrew Floyd Webber" joke was an improv by Jensen according to writer Robbie Thompson.
When Dean is explaining to Claire the value of her father's sacrifice he says "Cas was able to save the world." Not really an improv but the line got changed in performance and was written as "Cas was able to help save the world", according to writer Robbie Thompson.
- When Sam first meets Eileen, he uses the sign for "fuck" instead of "thank you". This was something Shoshannah Stern and Jared came up with together source.
- According to a tweet by writer Robbie Thompson, Dean stealing the Viagra was unscripted, and was ad-libbed by Jensen Ackles.
Lucifer: Don't you think about it too long. You know what they say... he who hesitates... disintegrates
As Claire starts teasing Alex about having sex, Sam goes to get up from the table and Jody says: "Sit! Stay!" which was improvised by Kim Rhodes.
Dean's speech to Chuck was originally scripted as Dean in "righteous anger mode," it was Jensen's choice to play the scene more tearful / emotional.
Dean falling over the gate and Sam walking around as they go to the Peterson house was unscripted.
The scene near the end of the episode when Dean wants to take the grenade launcher from the trunk of the Impala, and Sam dissuades him was unscripted.
In the script the bunny was just supposed to be nudging at Dean and then he wakes up. Jensen took it upon himself to pick up, pet and say “hey buddy” to the rabbit.
In the lobby of the hotel, Dean pockets a handful of mints. This was Jensen's idea.
Jensen improvised saying "Fucking right you can! to Fred, although the profanity was beeped out for broadcast.
Castiel's German accent was not scripted and was something Misha decided upon after seeing Apocalypse World Castiel's wardrobe for the episode, a choice Misha has apologized for since the episode aired.
The scene where Sam, Dean and Cas are sitting are toasting Jack after he has died, and are laughing and smiling was the actors not in character. As per Jared: "Yeah, ... that was just us fucking around."
During the fight in Hell, Jensen ad-libbed the line "Are any of us even winning?"
