This is a parody of the Santa Christmas as imagined told by the X-Files characters.

Mulder	We're too late! It's already been here.
Scully	Mulder, I hope you know what you're doing.
Mulder	Look, Scully, just like the other homes: Douglas fir, truncated, mounted, transformed into a shrine; halls decked with boughs of holly; stockings hung by the chimney, with care.
Scully	You really think someone's been here?
Mulder	Someone, or something.
Scully	Mulder, over here -- it's a fruitcake.
Mulder	Don't touch it! Those things can be lethal.
Scully	It's O.K. There's a note attached: 'Gonna find out who's naughty and nice.'
Mulder	It's judging them, Scully. It's making a list.
Scully	Who? What are you talking about?
Mulder	Ancient mythology tells of an obese humanoid entity who could travel at great speed in a craft powered by antlered servants. Once a year, near the winter solstice, this creature is said to descend from the heavens to reward its followers and punish disbelievers with jagged chunks of anthracite.
Scully	But that's legend, Mulder -- a story told by parents to frighten children. Surely you don't believe it?
Mulder	Something was here tonight, Scully. Check out the bite marks on this gingerbread man. Whatever tore through this plate of cookies was massive -- and in a hurry.
Scully	It left crumbs everywhere. And look, Mulder, this milk glass has been completely drained.
Mulder	It gorged itself, Scully. It fed without remorse.
Scully	But why would they leave it milk and cookies?
Mulder	Appeasement. Tonight is the Eve, and nothing can stop its wilding.
Scully	But if this thing does exist, how did it get in? The doors and windows were locked. There's no sign of forced entry.
Mulder	Unless I miss my guess, it came through the fireplace.
Scully	Wait a minute, Mulder. If you're saying some huge creature landed on the roof and came down this chimney, you're crazy. The flue is barely six inches wide. Nothing could get down there.
Mulder	But what if it could alter its shape, move in all directions at once?
Scully	You mean, like a bowl full of jelly?
Mulder	Exactly. Scully, I've never told anyone this, but when I was a child my home was visited. I saw the creature. It had long white shanks of fur surrounding its ruddy, misshapen head. Its bloated torso was red and white. I'll never forget the horror. I turned away, and when I looked back it had somehow taken on the facial features of my father.
	Impossible.
Mulder	I know what I saw. And that night it read my mind. It brought me a Mr. Potato Head, Scully. It knew that I wanted a Mr. Potato Head!
Scully	I'm sorry, Mulder, but you're asking me to disregard the laws of physics. You want me to believe in some supernatural being who soars across the skies and brings gifts to good little girls and boys. Listen to what you're saying. Do you understand the repercussions? If this gets out, they'll close the X-files.
Mulder	Scully, listen to me: It knows when you're sleeping. It knows when you're awake.
Scully	But we have no proof.
Mulder	Last year, on this exact date, SETI radio telescopes detected bogeys in the airspace over twenty-seven states. The White House ordered a Condition Red.
Scully	But that was a meteor shower.
Mulder	Officially. Two days ago, eight prized Scandinavian reindeer vanished from the National Zoo, in Washington, D.C. Nobody -- not even the zookeeper -- was told about it. The government doesn't want people to know about Project Kringle. They fear that if this thing is proved to exist the public will stop spending half its annual income in a holiday shopping frenzy. Retail markets will collapse. Scully, they cannot let the world believe this creature lives. There's too much at stake. They'll do whatever it takes to insure another silent night.
Scully	Mulder, I-
Mulder	Sh-h-h. Do you hear what I hear?
Scully	On the roof. It sounds like ... a clatter.
Mulder	The truth is up there. Let's see what's the matter.
