All I could think about the other day was this!
     I was listening to Tales From the Gas Station on audiobook and this popped into my head.
    So I'm imagining that instead the Ghostfacers met Castiel first. They're just chillin one day and all of a sudden Cas pops up like in the scene ^^ and scares the crap outta them.
    After that, they put the video of it online and it goes viral so Sam and Dean find out and Cas has to erase everyone's memories MIB style.
    Once he does that, Sam and Dean come in dressed as FBI agents and talk to the Ghostfacers and looking super serious and scary.
    Then, Sam says, "Don't bother trying to tell anyone we were here. No one's gonna believe two FBI agents were in here."
    And Dean adds, "Two sexy agents."
    "Really, Dean? Was that neccessary?" Sam giving him the bitch face.
    Then they just roll out.
    Idk why I always think of weird shit like this???
