The publicity department at Warner Brothers Television has once again provided the media with sneak peek teaser clips from an upcoming episode of Supernatural Season 4, which stars Jared Padalecki and Jensen Ackles as Sam and Dean Winchester: two always on the go monster hunting, ghost chasing, demon hunting brothers.

After School Special,” will air on Thurs., 1/29 at 9:00 p.m. ET/PT on The CW.

In the episode, Sam (Jared Padalecki) and Dean (Jensen Ackles) look into a possible haunting taking place at one of the many schools they briefly attended while they were growing up.  Dean is not thrilled to be returning, but Sam takes a special interest in making the trip.  Flashbacks to when the Winchesters attended the school give insight to a childhood spent on the move with a largely absentee dad.  Guest starring Colin Ford as ‘Young Sam’ and Brock Kelly as ‘Young Dean.’    “After School Special” was written by Andrew Dabb & Daniel Loflin and was directed by Adam Kane.

The episode sounds like it promises to be a good one as far as insight into what makes the Winchester brothers tick and I have to say that the sight of Dean Winchester (Jensen Ackles) in a pair of tight red gym shorts is worth the price of admission.

Check out the clips provided by Warner Brothers and tun into the Supernatural this Thursday at 9PM EST to watch After School Special.
