'Supernatural': Misha Collins meets the Ghostfacers

misha-collins-ghostfacers-supernatural.jpg "Supernatural" doesn't return to The CW until Sept. 23, but we've got a fun mid-hiatus treat for all of you Castiel fans!

Last year, we loved the "Supernatural" spin-off web series "Ghostfacers," featuring our favorite fumbling ghost hunters Ed ( A.J. Buckley) and Harry ( Travis Wester). But we didn't get to see all of it.

In the middle of "Supernatural's" fifth season, series star Misha Collins approached Buckley and Wester about their hilarious characters, who he didn't have the opportunity to interact with on The CW show. "He came up to us and told us he wanted to be on our show," Buckley told FearNet. "We pitched an 'Interview With an Angel' piece to ['Supernatural' creator Eric Kripke, who loved it.  We had a blast shooting it."

After "Supernatural" was picked up for Season 6, however, the "Facers" were asked to keep the segment under wraps. Until now!

Check out the episode below, in which the Ghostfacers are introduced to Castiel - who they refer to as a "TOSH" - translating opaque spectral humanoid, naturally. You won't want to miss the callback to the Season 3 "Ghostfacers" episode (R.I.P Corbett!) or Castiel's inability to repair the shattered Shatner.
