Author's Notes: I don't own it.

Harry Potter was pushing his breakfast around on his plate and sulking, as usual. Ron was stuffing his face full of bacon and eggs, as usual. Hermione was reading Hogwarts: A History, as usual. Ginny was glaring at her brother's disgusting eating habits, as usual. Snape was jumping up from his seat at the staff table and obnoxiously croaking (singing?) "Five, Six, Seven, Eight!" as usual…wait a minute!

Snape turned a remarkable shade of pink and jumped back down, muttering some very colorful words under his breath and cursing Harry Potter's existence, in general. Harry, following Snape's cue, leaped up onto the Gryffindor table and started singing a song from Chicago: All That Jazz.

Harry:
Come on Gin
Why don't we paint the town?
And all that Jazz

Harry extended his hand towards her, so she could join his performance. She readily accepted his hand and accompanied him in the song. "Ginny," Ron shrieked, "What are you doing!"

Ginny:
I'm gonna rouge my knees
And roll my stockings down
And all that jazz

Fred and George walked into the Great Hall the next day with a spring in their step. Nothing seemed to cheer them up more than a good prank. The spell they enacted didn't specify what would happen exactly, but, merely, it stated that the songs would choose their singers. Interesting, very interesting.

George and Fred had placed a few bets on who would get stuck with what songs. So far, George had proclaimed that Hermione would be one of the Cell Block Tango people, and Fred had decided that Ginny would be singing right along side of her. Neither could decide what Snape would be singing, but they knew it would be something…entertaining.

Neither of them, however, had prepared themselves for the sight that was waiting for them inside of the Great Hall. To be precise, at the Gryffindor table. All they were capable of at the moment, was standing there, gaping. After a few seconds, they shook it off and took a seat to watch the show and gloat about their brilliance (Total insanity?).

Harry:
Grab your broom
I know a magic spot
Where the gin is cold
But the piano's hot

"You're not going anywhere!" Ron shouted, but he could barely be heard over the background music, tap dancing, and singing.

Ginny:
It's just a noisy hall
Where there's a nightly brawl
And all
That
Jazz

Fred and George:
Skidoo!

Ginny and Harry:
And all that Jazz

Ravenclaws:
Hotcha!

Hufflepuffs:
Magic!

McGonnagal:
And all that Jazz

Staff:
Ha! Ha! Ha!

Ginny to Harry:
So fix your hair
And wear your magic cloak
And all that Jazz

Harry:
I hear that Brother Ron
Is gonna blow a fuse
And all that Jazz

Ginny:

Hold on, hon
We're gonna hex Malfoy
I bought some pranking junk
Down at the twin's prank shop
In case you twitch apart
And want a brand new start
To do that-

Dumbledore:
Jazz

Ginny:
Find your map
We're going to throw dung bombs

Slytherins:
And all that jazz

Harry:
Right up here
Is where I store the brooms

Gryffindors:
And all that jazz

Harry:
Come on, babe
We're gonna brush the sky
I bet your luck, Ginny
Never flew so high

"Harry Potter!" Ron was furious. "LEAVE MY BABY SISTER ALONE!"

Ginny:
'Cause in the stratosphere
How could I lend an ear
to all that Jazz?

Harry: Oh, you're gonna see your sheba shimmy shake

"Oh, no," Ron shouted, "she bloody well isn't!"

Staff Table:
And all that jazz

Harry:
Oh, she's gonna shimmy 'till her garters break

"I will let her do no such thing!" Ron shook his fist menacingly. "Ginerva Weasley, get off of that table this insant!"
Ravenclaw:
And all that jazz

Harry:
Show her where to park her girdle
Oh, her brother's blood'd curdle

"You bet your arse!" Ron growled.

McGonnagal:
If she'd hear her potion boils
For all that jazz

Hermione:
And all that jazz

Harry:
And all that jazz
Come on babe
Why don't we paint
The town?
And all that jazz

Ginny:

I'm gonna
Rouge my knees
And roll my
Stockings down
And all that jazz

Harry:

Grab your broom
I know a magic spot
Where the gin is cold
But the piano's hot
It's just a noisy hall
Where there's a nightly brawl
And all that-

Neville:
Jazz

Ginny:
No, I'm no one's wife

Harry:

But, Oh, I hate my life

Harry and Ginny:

And all that Jazz!

Snape (really loudly):
That Jazz!

Snape clapped his hands over his mouth and bravely ran away from the Great Hall and a chuckling Headmaster.
