Twas the night before Christmas And all through the house
Not a person was festive I had reasons to grouse
The cameras were hung by the entry with care
In the fear that the Slenderman soon would be there
My dog all a shivering, and I with my light
Had just settled down for a long sleepless night
What outside my window arose such a clatter
I sprang from the bed to see what was the matter.

Away to the window, my light did I flash,
Pulled up the blinds and pulled on the latch
Standing out there in the new-fallen snow
giving the lustre of mid-day to objects below
what to my wondering eyes should appear,
But old Slenderman? Oh, my heart filled with fear
When I knew what I saw, so lively and fast,
I got my weapons and readied to fight to the last

More rapid than eagles my crossbow did shoot
I shot in his head and shot in his foot
"Take this one and that one, and another to spare!
I'll fill you with holes till your nothing but air!
Away from my porch! Away From my wall!
Now run away! Run away!I'll shoot off your balls!"

Without so much as a word in reply
He raised up a hand straight into the sky
And then, in a twinkling, I heard on the roof
Not the sounds of Reindeer, but the sound of a boot

As I ran from the window and hurried downstairs
There stood the Slenderman without nary a care
Standing so smugly right next to the tree
I was so frightened I wanted to pee

His clothes were all tarnished with ashes and soot.
From his slenderman face to his slenderman suit
I knew in a moment he'd just break my back
And then I would be his Christmas eve snack.
I swung with my sword! I swung with my bat!
I gave him a bash! I gave him a slash!
But still there he stood! His look oh so merry!
I'd gave it my best, I knew I was ready
But then I knew something was odd, for my foe
On top of his head, as pale as the snow
Had a small furry hat, colored red and white
And somehow I knew he'd not come to fight.

He reached with one claw, so long and so handy
And took from my tree a single sweet candy
And then reached within the folds of his jacket
And handed to me a small weighty packet
He then walked and returned to the tree
And from his coat pulled presents for my family and me
I can't tell you how, and I can't tell you why
But tonight, just tonight, He's not a bad guy.

He finished his work, but before he could leave
I ran to the kitchen, and got him a treat
The plate full of cookies, left for St. Nick
But this time, for Slendy this might do the trick.
He took the plate, seemed to smile
I was glad for tonight, if just for a while
Peace and goodwill came not just for man
But for all of our enemies, even Ol' Slenderman

I waved him goodbye as he vanished from sight
"Happy Christmas to all, and to all a good-night!"

‘Twas the night before Christmas and many felt dread
For the Solstice had left quite a few bloggers dead.
The victims all handled their weapons with fear,
Believing the Slender Man soon would be near.

Noah Maxwell lay awake in his bed,
While visions of tentacles haunted his head.
And Jay with his camera, totheark with his mask,
Had just woken up from a seven-month nap.

When suddenly I had a terrible feeling.
I opened my eyes and saw blood on the ceiling
"The Angel of Death comes for all," the blood read.
I just rolled my eyes and I went back to bed.

But from out in the woods there arose such a racket
That I dashed outside, quickly grabbing my jacket.
When what, from the tendrils of fog did appear,
But a tall suited man with a plushie reindeer!

With a face with no features and limbs that were slim,
I knew in an instant it had to be Him.
I stood frozen as closer and closer he came.
In my mind a soft voice was heard calling my name.

Comehither, embraceme, takejoyinmyhugging
Andcomejointhefamily'saffectionateloving
Nowpickupyourgunandgodowntothemall
Andkillalltheshoppers! Yes, gokillthemall!

As I shrugged of the message and stared at his face,
I attempted to run...but my heart's all that raced.
Then up to the rooftop I managed to flee,
For that's rule 1 (I forget 2 and 3).

Then he vanished and reappeared right by my side,
And I silently cursed M and his bad advice.
I glanced for some help and saw no one around
As he let out a chuckle—a hideous sound

He extended a finger, and I followed to see
He had hung corpses up in an evergreen tree
Through the vomit, a thought struck that I knew was true:
He was trying to celebrate Christmastime too.

It seemed strange at first, right before I remembered
That he too had an important day in December.
He and Santa, if Broeckchen is right, have a link.
He'd be Santa's opposite evil, I think.

Then off in the distance, I heard sleigh bells chime.
I sighed in relief: Santa came right on time.
With my roof as a runway, he landed his sled,
I instantly knew I had nothing to dread.

He cut a clean figure in boots, coat, and hat.
I could hear the man mumble as he pulled out his sack:
"A trumpet for Nessa; for Robert, a knife.
Just two small reminders of their former life."

Then he looked at the Slender Man and said "Oh, dear.
So many bad kids have been wifin' this year.
But they don't deserve death, so you should be more lax.
Though Ron Browz," he mused, "probably could just be axed."

Then Santa found just one more gift in his sack;
Handed Slendy a twenny and patted his back.
As the Slender Man nodded then vanished from sight,
Santa cried "Merry Christmas, and to all, good night!""
