The Muses have struck!
Colonel O'Neill once said, "The first gate address is to a black hole. They get progressively darker from there."

Reggie Pine took a trip to a rave held in some nearby Indian caves and unexpectedly found himself in Equestria. Colonel O'Neill's comment above applies from this point forward....

I haven't decided as to put it in the same "universe" as Weirder Than Normal--Normal? Now That's Weird! or to keep this as strickly standalone, so I'm leaving that option open. The other story doesn't need to be read to understand anything mentioned here, but you might get a chuckle or two for any subtle references if you do.
