Hem, hem, J.K.Rowling created H.P. Clement Clarke Moore created "Twas the night before Christmas."
'Twas the night before Christmas when all through the Gryffindor house
NNot a creature was stirring, not even a mouse.
The stockings were hung by the chimney with care,
In hopes that St Nicholas soon would be there.
The students were nestled all snug in their beds,
While greedy thoughts of presents danced in their heads.
And Ron in his pyjamas, and Harry in his cap,
Had just snuck outside with the Marauder's map.
When Ron knocked over the armour, there was such a clatter,
Filch sprang from the corridor to see what was the matter.
Away from the floor Harry and Ron flew like a flash,
Lest they should get, from Flich, a bash.
They ran, they ran, beside doors and windows,
And they did not stop until they went out in the snow,
When, what to their wondering eyes should appear,
But a rickety old sleigh, and eight tinny Greptineers.*
With a little old driver, so lively and quick,
But they did not know if he was St Nick.
More rapid than eagles his coursers they came,
And he whistled, and shouted, and called them by name!
"Now Dasher! now, Dancer! now, Prancer and Vixen!
On, Comet! On, Cupid! on, on Donner and Blitzen!
To the top of the porch! to the top of the wall!
Now dash away! Dash away! Dash away all!"
As the wobbly sled began to rise very high,
When they meet with an obstacle, mount to the sky.
So up to the castle-top the coursers they flew,
With the sleigh full of Toys, and the person too.
And then, in a twinkling, they heard on the roof
The prancing and pawing of each little hoof.
As they drew inside the door, and was turning around,
Down the corridor Dumbledore came with a bound.
He was dressed all in fur, from his head to his foot,
And his clothes were all tarnished with ashes and soot.
A bundle of Toys he had flung on his back,
And he looked like a peddler, just opening his pack.
His eyes-how they twinkled! his dimples how merry!
His cheeks were like roses, his nose like a cherry!
His droll little mouth was drawn up like a bow,
And the beard of his chin was as white as the snow.
The stump of a pipe he held tight in his teeth,
And the smoke it encircled his head like a wreath.
He had a present labelled "Potter, Harry,"
That shook when he laughed, like a bowlful of jelly!
He was chubby and plump, a right jolly old elf,
But Harry and Ron were as frightened as a house-elf!
A wink of his eye and a twist of his head,
Soon gave them to know they had everything to dread.
He spoke not a word, but went straight to his work,
And through all the presents, the last one with a jerk.
And laying his finger aside of his nose,
And giving a nod, up the staircases he rose!
He sprang to his sleigh, and fell on his back,
And narrowly missed breaking his neck.
But they heard him exclaim, ‘ere he drove out of sight,
"Happy Christmas to all, and to all a good-night!"
"Dumbledore is crazy!" Harry exclaimed,
As his own toys he slowly claimed,
"Yeah, well, I always told you so,"
Said Ron, "Now the old man's secret we know!"
*Greptineers are horses that are made of ice. It is one of the things that Miss Lovegood claim to exist. It was cut from OoTP after a nasty argument with the pony club.
