September 4th 1995

Harry Potter stared moodily at his cauldron. His fifth year at Hogwarts School of Witchcraft and Wizardry had seen the introduction of a yet another new Defence Against the Dark Arts professor. Her name was Dolores Umbridge and Harry had taken an immediate dislike to her. This was mostly due to the fact she had been at the hearing he had, had to go to that summer. He'd gotten in trouble with the Ministry for using the Patronus Charm in front of his cousin. Umbridge had made no secret of the fact that she detested him. Harry's dislike of her had only increased after having been forced to sit through one of her classes. He had tried to convince of her of Voldemort's return but she had shouted him down and on top of that had given him detentions. Harry was so annoyed that he couldn't concentrate on his potions class. Without thinking he picked up an ingredient and added it to his potion. As soon as he did there was a puff of white smoke. Harry could only watch in horror as a vapour rose into the air and spread through the classroom. The effects were instantaneous, when the vapour vanished, the most peculiar behaviour came over the class of Gryffindors and Slytherins. Everyone seemed to forget what they were doing. They all leapt to their feet and started having a good old time dancing around the classroom.

When the class had ended and the fourth year Gryffindors and Ravenclaws arrived at the dungeon for their potions lesson; they froze in the door way. The sight that greeted them was; Hermione Granger and the normally straight-laced Professor Snape standing on a desk trying to teach the female students and Neville Longbottom, how to dance to a popular song by the muggle band the 'Spice Girls', they were singing very enthusiastically. The students laughed and stared with wide eyes, as the Professor and Hermione got to the chorus;

"Stop right now thank you very much, I need somebody with a human touch" while performing the actions. The gazes of the students followed from the dancing crowd at the front of the room, to some rather uncharacteristic behaviour by Harry and Draco Malfoy. They watched as Draco grabbed Harry by the waist.

"May I have this dance?" The pair began an elegant waltz around the room, Harry humming an equally popular song by Austrian composer, Johann Strauss II. Close to the waltzing couple were, Blaise Zabini and the Slytherin boys. Blaise was speaking rapidly with rhyme and lyric; he was rapping, while several of the other Slytherin boys were, making fantastical noises using only their mouth, lips and tongue. One of the fourth year students recognized it as 'beatboxing'. And much to Ginny Weasley's horror she saw her brother attempting to break dance. Lastly they noticed Seamus Finnigan and Dean Thomas, dancing an Irish jig. Seamus singing, what sounded like a rousing Irish drinking song.

"What on earth is going on here?" Luna Lovegood asked finally. Ginny just shrugged at her.

"Your guess is as good as mine" she replied. After they got over the initial shock they decided that it was actually quite amusing.

"Well this certainly beats having a potions lesson" said a Gryffindor fourth year boy. Some of the other students murmured in agreement. The Ravenclaws however; were shocked, above all else they valued education and right now the person who was supposed to be teaching them was busy dancing on a tables and singing, very badly too, one might add.

Meanwhile the students in the classroom didn't pay them any attention and continued to prance around, enjoy themselves unaware that they now had an audience. This was probably a good thing as Professor Snape probably would have been furious, had known that students were watching him and laughing as he made a fool out of himself. Harry and Draco continued to waltz around room, holding each other rather intimately, while Neville was proving himself quite the talented dancer. Ron Weasley was continuing his attempts at break dancing and Dean and Seamus had broken a sweat. The younger observers were enjoying the spectacle, some even joined in. Ginny, flushed with embarrassment when she saw, Ron attempting to do 'the worm'.

"Ok, I'm going to go and get Madame Pomfrey" One of the disapproving Ravenclaws stated before hastily running off to find the matron.
