It was before Christmas vacation started, and Dumbledore had called an assembly. Of course, in the midst of singing jungle bells, he hadn't exactly expected a war to break out. A war that started something like this:

Jingle Bells

Draco smells

Umbridge laid an egg

Dumbledore thinks that Lucius stinks

And Buckbeak flew away.

The angry Slytherins convened for a moment before joining in with song of their own.

Jingle Bells

Potter Smells

McGonagall laid an egg.

Umbridge thinks that centaurs stink

And Draco saved the day!

Amidst the angry glares of the Gryffindors, members of DA, or Dumbledore's Army, emerged from Ravenclaw, Hufflepuff, and Gryffindor tables.

Jingle Bells

Umbridge smells

Cornelius lost his mind

We all think dementors stink

And Voldemort is a swine

Annoyed, but out of ideas, the Slytherins could do nothing but continue to glare at the triumphant everyone else. But as the great hall doors flew open and a crowd of death eaters glided in, everyone fell silent. Then they uttered the worst words ever heard.

Jingle Bells

The Order smells

The Dark Lord has returned

Now the Dark Mark shines above

And we shall kill you all!

Only a couple people were mystified about the sudden appearance of Death Eaters at Hogwarts. The others… they didn't care much. They were watching several people at the High Table stand. And even more were shocked when several more Apparated in. Mr. And Mrs. Weasley, Mundungus Fletcher, Remus Lupin, and Mad-Eye Moody. Everyone was shocked when they too started to sing.

Jingle Bells

The Dark Mark Smells

The Order shall prevail

Voldemort's lost, the final fight

And peace shall reign again.

Death Eaters glared, and the Order glared back, but everyone stopped to stare when who should Apparate in but… Lord Voldemort himself. And everyone rushed to cover their ears when he opened his mouth, sure that doom would fall upon them now. But he started to sing.

Jingle bells

Kindness smells

Dumbledore laid an egg

Mudbloods we exterminate

And I shall rule the world!

Many people were writhing on the floor in pain.

"It burns!" Harry .

"The noise!" Ginny shrieked

"Put the creature out of its misery!" Lavendercalled.

"BOOO!" Dean and Seamus voiced

"My ears…they shall never be the same again…" Luna Lovegood muttered.

"The pain…the pain…" Neville said covering his ears

"He can't sing to save his life!" McGonagall yelled.

"I agree." Dumbledore yelled back.

Then one person stood up. It was Hermione Granger.

"This isn't possible. Haven't any of you read Hogwarts: A History? It's impossible to Apparate or Disapparate on Hogwarts grounds! This can't logically be happening!"

Everyone stared at her for a moment, before each of those who apparated in disappeared without a sound.

"Ah! Hermione! You ruined all the fun!" Ron screeched at her, his ears still ringing, he could hardly hear himself.

And then, the feast commenced, no one even remembering this ever occured.
