I'm Dreaming of a Black Yuletide

I'm dreaming of a black Yuletide
Twill be like none we've ever known,
When the spear tips glisten
And Uruks listen
To the screams of Gondor's tarks o'erthrown.
I'm dreaming of a black Yuletide
With every lesser orc I thwack.
May we rape and pillage and sack
And may all of Middle-earth be black.
