10 Unscripted Supernatural Moments That Were Kept In The Show

10. Dean's Famous Catchphrase

Anyone who watches Supernatural, whether avid fans or not, knows what Dean’s famous catchphrase is. However, not many know that Jensen Ackles improvised this phrase multiple times throughout the show as it was only meant to be used as a one-off during one of the earlier seasons.

The improvisation of his catchphrase can be most noticeably seen in the season three episode, Bad Day at Black Rock. After Sam starts to lose all his luck when Bela Talbot steals the lucky rabbit foot from him, the brothers go on a mission to retrieve that item in which Dean ends up accidentally touching the foot, gaining himself an unprecedented amount of luck. With this, Dean decided to buy himself winning lottery tickets in the hopes that’ll it makes the brothers rich.

However, Dean’s luck runs out after they destroy the rabbit’s foot, finding out that Bela stole the winning tickets from the brothers and gained the prize money for herself. After learning about Bela’s betrayal (yet again), Dean lets out a frustrated version of his famous phrase.

If you watch the episode closely, you can see Jared Padalecki smiling and holding in his laugh as he turns away from the camera, since Dean’s outburst was unscripted but Jensen cleverly added this in, knowing that it was in-character for Dean.
