Who ya gonna call? WINCHESTERS!

After killing us with an epic Supernatural spoof in 2015, The Hillywood Show is back at it with another hilarious parody, and this time the list of guest stars is so insane it's practically a real episode of the CW drama. And not for nothing, but THIS version of Supernatural doesn't forget about Adam.

In a 10-minute spoof on Ghostbusters, the Winchesters — Hilly Hindi appears as Dean (Jensen Ackles) while Osric Chau is Sam (Jared Padalecki) — are armed with proton packs, salt, and a few additions to the Impala that border on sacrilege, but we'll go with it.

The musical is obviously a great bit of fun for Supernatural fans, but also for a very long list of current and former cast members who swung by for cameos — including Jared and Jensen! We're still trying to count them all, but we're pretty sure this is the full list of guest appearances:
