Fridge Logic or Fridge Brilliance?

Had the revelation earlier today (in the midst of post-thesis insanity; first draft is done!) that one of my favorite X-Files fanfics back in the day, and I'm talking nine, ten years ago here, was basically almost an early version of Life on Mars/Ashes to Ashes. Which is either really freaky or really cool. And dammit, now I want to reread that story, and I can't remember where the hell I found it...
