The CW network released on Tuesday, January 28, the promo video for upcoming "Supernatural" Season 9, Episode 13 "The Purge" and it looks like hilarious things are going to happen. Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) will be going undercover for the nth time to investigate a case but the roles that they took in secret this time will make the hunter brothers make fun of each other.

The promo video in the CarterMatt report begins with the commercial for the Canyon Valley Wellness Spa where the female endorser guarantees the viewers that they can lose weight without surgery. The ad sounds really enticing since the spa assures they can do it in just one day.

However, the spa's customers end up as murder victims with their weights becoming hundreds of pounds lighter so the Winchester brothers go undercover to find out who or what is responsible for the killings. Sam ends up as the spa's fitness instructor while Dean's duty is in the kitchen.

The funny part in the video has Dean commenting that Sam has "nice shorts" and the younger Winchester poked fun at his brother telling him that he has a "nice hairnet." The two may still be in conflict with each other but it looks like Sam and Dean will put their differences aside for a moment in order to solve the case.

Suspecting witches, the two go undercover at a fancy day spa that all of the victims had attended for weight loss. While Sam is hired as a fitness instructor, Dean takes kitchen duty. After Dean swipes some tainted food and passes out, the guys realize someone is drugging the guests and literally sucking all of the fat out of them until they die."
