'Supernatural' casting scoop: 'Road Trip's' D.J. Qualls gets on Dean's last nerve

In its seventh season, "Supernatural" is going all-out when it comes to the guest stars who keep the story colorful, and this bit of casting scoop is no exception.

Zap2it has exclusively learned that D.J. Qualls -- best known for his memorable role as nerdy virgin Kyle in the comedy classic "Road Trip" -- will intercept the Winchesters in the season's 8th episode, tentatively titled "Time for a Wedding."

Qualls plays Garth, a quirky, laid-back hunter who Dean (Jensen Ackles) clashes with right off the bat.

Let's just say that Dean definitely wouldn't be working with him if Garth wasn't the only hunter available, and if it wasn't a dire emergency. Hijinks ensue, we're sure!

Though he'll forever be Kyle to us, Qualls is no stranger to television audiences -- most recently, he starred on TNT's "Memphis Beat" as Officer Davey Sutton.

Tune in for the Season 7 premiere of "Supernatural" this Friday, Sept. 23 at 9 p.m. EST on The CW.
