Narrator: CASE FILE #1024 THE SLED
T-Rex: Thank you all for coming: I remind you this meeting is classified. This briefing is about a superficially ordinary cargo sled under the control of Case #1023, usually used on Christmas Eve.

T-Rex: This sled allows access to millions of complicit families, all within a single 24-hour period!

Dromiceiomimus: While the reasons for these visits remain classified - thankfully obscured by constructed myth - the method used for them can be shared with you today: Agents, this Sled allows for selective logical addition of quantum realities. Put simply: elements of alternate timelines can be merged into our own.
T-Rex: If you choose 100 randomly-selected houses to deliver presents to -

Utahraptor: - then there's an alternate reality where 100 different houses were chosen!
T-Rex: Precisely. Doctor?

Utahraptor: Subject interfaced with the Sled can selectively collapse those realities into ours, which results in a final timeline in which every good little girl and boy gets a present.
T-Rex: When "Rudolph" went against "Frosty" this afternoon, he failed. But we were able to use the Sled. And now, he was successful.

T-Rex: But overwriting the trillions of timelines in which we failed with our only victory led to some side-effects, including 175,250,000 alternative "Rudolph" corpses that materialized in a fused-together mound near the North Pole.
T-Rex: Cleanup duty begins at 0800. Dismissed!
