"Whose next?" Dumbledore asked, in a near-growl.

"We are," the Weasley twins said together, "And we'll be singing Percy Snitched On Us."

"Very well. Whenever you two are ready." The twins got up on stage and started to sing (Fred/George/Both):

"We broke our bat on Ronnie's head

Percy snitched on us

We hid Trevor in Mione's bed

Percy snitched on us

We spilled some ink on Snapey's rug

We made Draco eat a bug

Gave his dad a big slimy slug

Percy snitched on us

Oh, we're gettin' nuttin' for Christmas

Even though Dad is laughin like mad

We're gettin' nuttin' for Christmas

Cause Mum says we've been nuttin but bad

We put a tack on Pansy's chair

Percy snitched on us

We tied a knot in Ginny's hair

Percy snitched on us

We did a dance on Neville's plants

The Whomping Willow tore our pants

We filled Percy's bed with fire ants

He still snitched on us

So, we're gettin' nuttin' for Christmas

Mum is seriously mad

We're gettin' nuttin' for Christmas

Cause we ain't been nuttin' but bad

We wont be seeing Santa Clause

Percy snitched on us

He won't come visit us because

Percy snitched on us

Next year we won't even go strait

Next year we'll be worse, just wait

We'd start now, but it's to late

Percy snitched on us

We're grounded real good, it's true

But hear this Percy; we're warning you

Next year your gettin' nuttin but

PRANKS!"

Snape walked into the Great Hall as the Weasley twins finished.

"Ah, Severus. The Weasley twins just finished their song. Would you like to go next?" Dumbledore said.

"NO!" Snape yelled and ran from the room.

"Oh, well. Anyone else want to go?"

"Oooh! Oooh! Let me! Let me!" Trelawney squealed.

"I though Dumbles killed her," Minerva muttered.

"Alright Sybil. And what will you be singing?"

"Oooh! I'll be singing…"
