Intro

I have a song stuck in my head. It's been there for a week. I wake up every morning humming Watermelon Sugar and I'm ready to hurt someone... or dance, it's a toss up. Unfortunately, it's not one that I can use for a story prompt but thankfully this is.

- Day 10 -

The prank happened at breakfast on a Monday. The victims were spread among the Great Hall. Students and faculty alike were seen standing and singing at various times during the meal. Sometimes together, sometimes in a sort of round, most often they simply sang over each other. It made for a chaotic, yet entertaining meal.

Unfortunately for Harry, he had stood up twice to sing during that meal and it didn't look as if he'd ever stop. It was now Thursday dinner in the Great Hall and Harry had been up three times to sing already. Harry glared at the guffawing Weasley twins as he stood for the fourth time that day:

Double, double, toil and trouble; Fire burn and cauldron bubble. Double, double, toil and trouble; Something wicked this way comes.

[insert a lot of humming and hawing, with occasional duh, duhs and la, la, las]

Something wicked this way comes!

The poor guy. He was the only one left still singing... or humming. Harry sat down as soon as he was able and his glare intensified, "Make it stop!"

"Can't," Fred admitted.

"What do you mean, you can't?" Harry asked in exasperation.

George replied, "Only you can break the curse."

Harry sighed in resignation. He had to get the curse broken soon. He nearly fell from his broom during quidditch practice and there was a game in two days against Slytherin. Their rivals were relentless and if Harry had to stop to sing/hum, there was no telling what they'd do to him. Harry peered at the twins and asked, "How?"

The twins exchanged a look before Fred explained, "You have to perform the song in its entirety."

"You can't hum the words, you must sing it word for word, note for note," added George.

"Even off key will suffice," Fred shrugged when Hermione frowned at him. It wasn't his fault the girl was tone deaf and couldn't carry a tune in a bucket. Thankfully her curse was already gone.

Harry stared at his treacle tart. He was desperate. He had to stop singing. Harry walked up to the head table, spoke softly with Professor Flitwick, before the two left the Great Hall together.

The twins exchanged another glance, both grinning like the loons they were.

It was at dinner the next day that had the headmaster standing at his podium. He looked over his half moon glasses waiting for the students to quiet down and then he cleared his throat. Professor Dumbledore gave them all his grandfatherly smile and introduced a special treat for the evening.

Harry stood then. He walked to the front of the Great Hall and ignored the curious whispers. Professor Flitwick met him in front of the head table and gave the boy an encouraging smile before handing him a large cage. Harry reached in and withdrew a very fat frog.

By the time Professor Flitwick walked away, Harry began singing to the rhythm set by the frog in his arms.

Double, double, toil and trouble; Fire burn and cauldron bubble. Double, double, toil and trouble; Something wicked this way comes!

It was during the first verse that one by one, the Frog Choir joined him. Each holding a large amphibian.

Eye of newt and toe of frog, Wool of bat and tongue of dog, Adder's fork and blind-worm's sting, Lizard's leg and owlet's wing.

Double, double, toil and trouble; Fire burn and cauldron bubble. Double, double, toil and trouble; Something wicked this way comes!

As each choir member joined him, Harry's confidence grew and his voice rang out with the others, blending and harmonizing.

In the cauldron boil and bake, Fillet of a fenny snake, Scale of dragon, tooth of wolf, Witches' mummy, maw and gulf.

Double, double, toil and trouble; Fire burn and cauldron bubble. Double, double, toil and trouble; Fire burn and cauldron bubble.

Double, double, toil and trouble; Fire burn and cauldron bubble. Something wicked this way comes!

The applause was thunderous from all tables, save one. The Slytherins were disappointed that Harry would no longer be distracted with that rather annoying song.

Harry gently replaced the frog in his cage, thanked the other members of the choir for their patience and help, then thanked Professor Flitwick.

Dinner was at an end, the students were released back to their common rooms for the evening. It was just as well that they had been, because the sudden explosion of sound coming from the Gryffindor table had the entire room stilling to see what was wrong.

Harry Potter was yelling at the Weasley twins as he chased them back to their tower. Professor Dumbledore chuckled softly, gaining the attention of the other staff members sitting nearby. Professor McGonagall looked at her long time friend and asked, "What is it, Albus?"

"Apparently the twins just confessed that a simple finite would have ended their prank days ago," the headmaster said and rose from his chair, "But then we would have missed out on such a lovely performance."

AN: And no, I did not count the lyrics to the song since I didn't write the song. That would be cheating.
