A/N: Hello again to the newest pranks from Loki. The music suggestion for this chapter came from Rosalind Fairchild. I hope you like what I did with it. Should anyone else have suggestions about songs I could work in this fic feel free to let me know (PM or Review…I don't mind). The problem is I mostly listen to metal and hard rock and I don't really know other songs so I'm glad for any suggestion.

So and now onwards with the chaos!

Chapter 6: Of Pranks and Bets

After he finished his evening meal, Loki went to Professor McGonagall's office for his detention. He had to write an essay about how to behave around teachers. With a smirk, he went to work. He was halfway through his piece when he saw that Professor McGonagall was carefully watching him.

"Is there a problem Professor?" he asked curiously.

McGonagall, ripped from her thoughts, slightly blushed upon being caught staring.

"I've just been thinking about something Mr Weasley told me this night. He was caught sneaking around the 6th years female Slytherin dorms. You don't happen to know anything about it, do you?"

"Well, from what I heard, it seems that he effectively woke everyone up there and got hexed for it pretty badly. Not to mention that they marked him as a pervert," he answered, suspicious about what the point behind all this was.

"So, you don't know how he got in there?"

"Should I?" he grew even more suspicious.

"Mr Weasley insisted that you ported him there with only a snap of your fingers."

Ah, so that's how the land lies. "We both know that this should be impossible. I assume that there are many wards around the school which prevent things like porting someone somewhere within them. Also, porting someone with only a snap of his fingers? I doubt that anyone who isn't a real master of the art could pull such a stunt and I'm just a first-year student" he told her with a grin which spoke of nothing good.

McGonagall narrowed her eyes. There was something about Loki she couldn't pinpoint. On the one hand, he was right. He was a first-year student at Hogwarts, so he shouldn't be able to do such a thing. But on the other side, there seemed to be much more about him. That had also shown the lesson this morning where he had transformed his matchstick without any real effort. She even heard the subjunctive in his explanation, so there really was something wrong, but she couldn't say what.

"Well, continue with your essay" she definitely would have an eye on him.

Half an hour later, Loki was back in the common room. He went straight to the twins who sat in a corner obviously planning something. Harry and Neville, who sat next to the fireplace, came over, and the three sat down with the twins.

"Guys, I need your help" Loki started.

They looked at each other before with a broad grin, they looked at him.

"What do you need, master?"

"Please stop calling me master" he growled, but upon seeing their puppy dog eyes, he sighed. "Okay, okay, if you really want to…I want to prank someone, and I need your help with it."

A malicious glee appeared on the twins' face, and Loki explained what he wanted to do. Even Harry and Neville, while not as eager as the twins but glad they could help, got a part in it and so they started to plan how to pull it off and prepared everything.

When they were done, they changed the topic.

"How was detention?" Harry asked.

"Had to write an essay about how to behave around a teacher. I also might or might not have started to drive Professor McGonagall nuts" Loki explained.

"Why, what did you do?" one twin asked.

"She asked me about what happened last night."

"We heard you ported Ronykins straight into the 6th year female Slytherin dorm,"

"where he effectively woke everyone up." They both grinned widely.

"Exactly. While doubting that a first-year student could do such a thing, McGonagall seems to be suspicious about me. As I neither denied nor confirmed that I did it, I dropped some hints about possibilities. Should be enough to drive her crazy not knowing what to think of it." Loki grinned.

After a bit more talking, they all went to bed eagerly awaiting the next day. Luckily for Ron, he didn't snore this night, so he didn't get a one-way ticket to another dorm this night. Only Neville snored slightly, but he didn't wake anyone up, so Loki left him be.

The next morning Loki, Harry, Neville and the twins sat at the Gryffindor table early with a good view on the Slytherin table. About half an hour later, Malfoy and his goons Crabbe and Goyle entered the hall and started to eat.

When they drank some, the prank set off. Suddenly there wasn't a boy with two gorillas anymore. Draco transformed into a 5' 11" tall platinum blond woman with long hair while his goons transformed into two playboys with brown hair of equal height. Just at that moment, Loki snapped his fingers, and Draco wore a very short pink dress together with pink high heels, and his hair was bound together with a large pink bow. Crabbe and Goyle in the meantime both wore a black suit.

All three started to dance while a song began to echo through the hall.

"I'm a Barbie girl in a Barbie world…"

A few heads rose in surprise, looking around what was happening.

"… I'm a blond, bimbo girl, in a fantasy world
Dress me up, make me talk, I'm your dolly…"

Malfoy Barbie and his Kens were now on the Slytherin table dancing. Quite a few who saw what was happening started laughing, especially the Muggle-born and the half-bloods who knew this song. Also, the five Gryffindor friends laughed at that sight.

"…Make me walk, make me talk, do whatever you please
I can act like a star, I can beg on my knees…"

Now Malfoy, who performed right on the song's text, was on his knees in a pleading pose. One Malfoy usually never ever would even think about taking. For the five Gryffindors, there was no holding back anymore. All five of them literally fell backwards off their bench and rolled on the floor, laughing.

"…You can touch, you can play
if you say, I'm always yours…"

(Barbie Girl - Aqua)

The teachers were too stunned to act. Only Dumbledore sat there grinning and swaying to the beat of the music.

Malfoy Barbie once more acting according to the lyrics started to snuggle with one of the Kens. Quite a few students didn't see that anymore. They either laid on the ground, sunk onto the table or their view was obstructed by tears. But they all howled with laughter.

When the song was over, and the dancing charms wore off, Malfoy ran out of the hall with a high redhead followed by his goons. Harry, who caught a breath, looked in his direction, and instantly started to laugh all over again.

After getting out of their shock, the teachers who tried to bring peace into the masses of students had a hard time. Except for Snape because the Slytherins only looked indignant around while McGonagall straight went to Loki and the Weasley twins.

"Who of you was this?" she demanded to know with a stern glare.

Loki who lay flat on his back trying to breathe normally looked at her and laughed.

"I have it on good authority that you have no evidence!" he replied when an idea struck him.

He took out his wand pointed it at his pullover and transformed it into a shirt with just that statement on it. The twins upon seeing it broke out into laughter once more. Even Harry and Neville, who had managed to sit on the bench again laughed too.

McGonagall sighed before she left with a last glare at them shaking her head because there was nothing she could do.

The incident had been the only topic of the conversations the whole day. Malfoy had been called Barbie Girl more than once, even after transforming back.

Wednesday and Thursday morning went without any more incidents.

On Thursday during lunch break, Loki told the Ravenclaw first years that he found an empty classroom right opposite the History classroom and would meet there.

Five minutes before classes started, Loki went to Professor Binns and informed him where most of his students were so that they didn't disturb his lesson and that he could find them there. Only three Ravenclaw's and Hermione decided to stay in the original class.

It was about seven minutes into the lesson. Loki was in the middle of telling them everything he knew about demons in detail when there was a knocking on the door. A few seconds later, the door opened, the four who decided to stay with Binns came in followed by the said professor.

"Since most of the class refuse to attend, Professor Binns thought it better to cancel the class for today and join you," Hermione told them, sheepishly looking at the floor.

"No problem with me. Take a seat. Where have I stopped…ah yes demon deals," Loki said before he continued his lecture.

He continued telling them about demons, hell and what else lived there. He also conjured up small animated versions of hell's beasts to show them how they looked or show them little scenes of historical events related to hell.

The lesson ended in the opinion of the most far too early. The students listened to Loki like hypnotised. Even Binns paid close attention, and most of them took several notes if only because of personal interest. After the bell rang, they departed with some moaning that the lesson was over. Still, Loki said that if they liked they could meet in this classroom again next History lesson. Binns interrupted him and said that they also could use the History classroom since it didn't really matter whether they all met here or there.

Because History was the last class of the day, they collectively went down to the great hall for dinner eagerly talking about what Loki told them.

Two hours later, Loki sat in McGonagall's office again having his last detention for now.

"Mr Laufeyson, I got to know that you again disturbed Professor Binns' class" she scolded him.

Loki raised an eyebrow. "How can I disturb a class when I haven't even been there?"

"Exactly! You and nearly the entire rest of the class have outright refused to attend class."

"Professor, you personally told me to not disturb the History lesson another time. So I thought up a method of avoiding falling asleep because of Professor Binns monotone teaching while not disturbing him. As I said last time, should you have a problem with it you should reserve your evenings for detention because I won't stop. Besides that, I hardly doubt that my classmates are more eager to listen to Professor Binns than to me."

McGonagall sighed and pinched the bridge of her nose. This would induce her a lot of headaches.

"Mr Laufeyson, I told you that it is important to learn history. You can't go on preventing your classmates from learning it."

Now Loki sighed before an idea struck him.

"What about a bet?" he replied.

McGonagall looked confused at him.

"You give me the syllabus of the first year History class. I'll teach it to my classmates until the Christmas holidays. If they can take the final exams of this year then and succeed you'll leave us be for the entire seven years. No complaining that they don't learn 'important' History. I'll make sure they learn the yearly syllabus. Still, how and the timeframe within each year I teach the necessary knowledge is up to me. As long as they can take their exams in the end and pass them.

"Should I prove unable to do so until the holidays, we gladly return to Professor Binns' class. I also promise to never again interrupt it in any way. You also can give me any punishment you see fit for it then."

She sat back in her chair, she had expected a lot but definitely not this. Yes, she knew full well how boring Binns lessons were because she got enough complaints about it. But up to now Dumbledore outright refused to change anything about it. Perhaps this was the perfect opportunity to show Dumbledore how grave the situation was. She didn't know why, but she doubted that Loki Laufeyson would not properly teach his classmates.

She heard how her Gryffindor's talked about today's History lesson and what Mr Laufeyson told them. It was profound knowledge even she hadn't, she wondered where he learned it.

So after thinking about it, she came to the decision that she would risk it. She knew how easy the exams at the end of the first year were and that most students slept in class anyway, reading the needed information later. So even with half a year lost it shouldn't really matter.

"Okay. I take the bet but shouldn't you perform as you promised I'll see that you will be expelled for it. The only requirement you have to fulfil is that Professor Binns is present in every lesson to ensure everyone attends. Still, he won't help you with rebelling students. This is entirely your problem. Understood?"

Loki nodded with a grin. "Sure. Do I get the syllabus from you or from Professor Binns?"

"Professor Binns. When there is nothing else you can go now, I think you have a lesson to prepare."

Again Loki nodded before leaving the room. McGonagall took out the scotch she stored in the drawer and a glass before pouring some in and drank. She prayed that this wouldn't become a too massive headache.

Before returning to the Gryffindor common room, he took a loop way to Binns office to get the syllabus of this year's History class and inform him of the arrangement. He also told the professor that he from time to time would change the location where the lesson would take place and that he will inform him beforehand.

Afterwards, he went to the common room where he slumped into an armchair in front of the fire. It got quite late, he was glad to have his peace now.

Harry, the twins and Neville joined him, and they talked about the prank from this morning.

-Flashback-

The twins provided the gender switch potion while Loki adapted it so that Malfoy looked like he did. They also applied the dancing charm and got the house-elves to spike the food from Malfoy and his goons with it. Harry in the meantime looked up the song after Loki conjured up a laptop that worked within the wards of Hogwarts for him with the best w-LAN you could get. Harry and Neville then fed small speaker-balls Loki also conjured up with it. They made them invisible following Loki's instructions. It took them several tries, but in the end, it worked.

Loki then connected everything so that the speakers would start to play when the spells and potions sat off. While waiting for Malfoy to arrive Loki and the twins then distributed the speakers. The result of everything could be seen a bit later. Only the clothing Loki did manually.

-Flashback end-

Now they sat in the common room again snickering about the spectacle, it had been hilarious.

Next Monday the History class once more met. This time Loki decided that with such warm and beautiful weather to not hide within the castle. So he told everyone, including Professor Binns, that they would meet next to the Black Lake. Now they sat on a slope leading down to the Black Lake, Loki standing in front of them.

"I spoke to Professor McGonagall last Thursday about our situation with the History class, we came to an arrangement. She allows me to tell you about supernatural things during the History lessons. That is under the condition that I also teach you the necessary information from the History lessons we are supposed to have. To prove that I'm capable of doing so I have until the Christmas holidays to teach you everything for this year's end exams," he told them.

"So we are supposed to learn everything we normally would have a year for within half the time?" Hermione asked anxiously, but Loki started to laugh.

"I talked to some of the older students…I could teach you everything needed within one week so that should be no problem."

Yes, all the questions asked were so easy even a child could do this. It seemed that the standard fell so low to make up for the teacher's incompetence, but that was nothing he would ever say aloud.

"But to do it properly I came up with a system. From now on I'll teach you history every Monday and tell you more about the supernatural on Thursday. Oh and don't think that because I'm no official teacher, you could do as you like and not pay attention. Even if I cannot deduct points or give detentions, I have my own methods of punishment. I doubt you want to learn them," he warned them.

"The thing is, should I fail to prepare you for the exams before the holidays you'll have to go back and listen to Professor Binns, and I'm most likely expelled. So if you don't want that to happen, you should pay attention."

With that, he started his lecture, this time about history. Again he helped his explanations with visualising several scenes. For example, he conjured up two small armies on the Black Lake to show them one of the goblin wars. Not as bloody or brutal as the real one but only to see the strategy behind it. He also told them things even Professor Binns didn't know of.

Everyone, even the laziest person, took notes. The way Loki taught them was far more interesting than their usual professor's droning. Everyone was eager to prove Professor McGonagall that Loki was the better teacher for the subject.

In the end, it was a good day. They were eagerly awaiting the next lesson, something that rarely happened before in Hogwarts in the last centuries, especially when it came to History of Magic.

A/N: So that was it for today and I hope you had as many fun as I had writing it. 'til next chapter.
