This one goes back a ways:
There is a wide-spread rumor of an anti-union, pretty much slave labor factory which 'employed' a minority race, keeping them in isolation in a far-flung gulag in a frozen wasteland. None of them had any contact with the outside world, and were kept captive and busy all year in the factory.
The evil dictator kept track of them with a list of subversives. The evil dictator also kept animals captive, strong, special animals which he trained for his own dastardly plans.
But once that year, that evil dictator took the fruits of their labor and whipped the poor animals aloft, leaving the minority race alone. They took their chance, and bolted out into the frozen wastelands. . .
. . . where they all froze to death.
The end.
