Sam and Dean Meet the Supernaturalists in “ThinMan” (Images & Scoop)

The Ghostfacers are back in Supernatural’s “Thinman,” an episode which promises to deliver some classic Supernatural moments with humour and horror combined.

Airing March 4, the episode will see the return of the creepy Ghostfacers and the “famous supernaturalists” (who also happen to be not Dean and Sam) who are called in to investigate some ghostly goings on.

Check the CW’s official log lines for the episode below:

A teenage girl (guest star Ali Webb) is killed and the final selfie she took before the attack shows a ghostly figure in the background.

Looking for something to keep them busy, Dean (Jensen Ackles) and Sam (Jared Padalecki) head to Washington to find the ghost. While the two interview the girl’s mother, Betty (guest star Maria Marlow), they are surprised when she starts talking about cold spots and fritzing.

When they ask her about bringing up paranormal signs, Betty replies that the “supernaturalists” who called earlier brought it up. Enter Harry (guest star Ryan Moss) and Ed (guest star A.J. Buckley), the famous supernaturalists.

Jeannot Szwarc directed the episode written by Jenny Klein.
