You asked for some Fred and George Mischief, and you got it :) I hope you enjoy it enough to review.

Hogwarts Headmaster, Albus Dumbledore, prided himself on his calm demeanor. He was always in control; he never lost his temper, and he never yelled at students. However, as with all rules, there was an exception. Actually, there were two.

No one except Fred and George Weasley could make the Headmaster so...he struggled to find the right word, and settled on exasperated.

Currently, Dumbledore was sitting at his desk in his office, his fingertips pressed together in front of his face. He was staring at the red-headed twins, biting back a sigh.

"To what, may I ask, do I owe the pleasure this time, boys?" the Headmaster asked.

"Funny you should ask," George said, grinning from ear to ear. He turned to his brother. "Would you like to do the honors, Fred?"

"Gladly," Fred grinned back, a mirror image of his twin, "You see, Professor Dumbledore…it started like this…"

"Bloody Hell!" Fred exclaimed, trying to control the stomach wrenching cough that was escaping his throat, "We need to find a better way to test our merchandise!"

"You're right…" George replied, looking into the small mirror he was holding. His face was covered in sickly green markings, which made him appear violently ill.

The brothers had been testing out their Skiving Snackboxes when they had discovered that the "curing" half of the pill failed to work. Now they were forced to test alternative cures, all the while dealing with the side effects of the "sweets that make you ill."

"At least you only look ill," Fred coughed, "I feel like I'm going to cough up a lung at any moment!"

"Oh come off, it can't be that bad," George said, smirking slightly.

"Oh? Then why don't you have one?"

"Er…no thanks."

"That's what I thought. Come on, let's keep trying."

Finally, after an hour longer of coughing and looking green, they found the right combination of ingredients to cure their symptoms.

"I'd say it's high time we find some test subjects…" Fred said, immensely relieved that he could breathe correctly again.

"Good idea," George replied.

"I fail to see the humor in this story, so far," Dumbledore said, his lips pressed together in a hard line.

"It gets better, I promise," Fred said.

"Then please, do go on," the Headmaster sighed.

"So, one Galleon a day and you'll test our products, deal?" George asked the timid looking first year in front of him. "It's not dangerous, I assure you…"

"Well, not life threateningly so, anyway," Fred snickered, causing George to punch his arm roughly.

"So, Brian was it? Do we have a deal?" George asked.

"How about two Galleons a day?" Brian asked, plucking up the confidence to speak.

"That's robbery!" Fred exclaimed, "Two Galleons, are you mental?"

"One Galleon and five Sickles," George offered, ignoring his twin.

"One Galleon and eleven Sickles," Brian challenged.

"One Galleon, nine Sickles," George countered.

"Deal," Brian grinned.

"I like this kid," George laughed, "He's goin' places."

"I don't wish to hear the specifics of how much money you offered Brian Voss," Dumbledore said, "What I would like to know is how the poor boy ended up floating around the Great Hall ceiling, unable to get down!"

"Right…that bit," George said, "It's a funny story. You'll laugh, I promise." The look on Dumbledore's face suggested otherwise, and George hurried forward with the story.

"Are you sure about this?" Brian asked, looking doubtfully at the candy Fred had just offered him.

"If you don't want to test it, then I'll take the money back and we'll find someone else," Fred said, "It's up to you."

Brian scowled at the fifth year and snatched the purple piece of candy away from him. He took a bite and swallowed. For a moment, Brian felt nothing happening.

"It doesn't work, geniuses!" Brian shouted.

"I don't get it! The Levitation Licorice worked perfectly in our tests!"

"Well, we did try it on a mouse first….they're quite a lot lighter than Brian here," George sighed, "Maybe we need to add more-."

Before George could finish his sentence, Brian began to lift away from the ground. The first year yelped in surprise as gravity seemed to shut off.

"It bloody works!" Fred shouted joyfully.

"Fantastic," Brian shouted, "Now how do I land?"

"Err…" Fred muttered, "About that…"

"WHAT?" Brian exclaimed, "You bloody morons didn't think of a way to stop this?"

"Hey, watch who you're insulting! Just give us half a mo, we'll figure this out!" George shouted, and then turned to Fred.

"So…I see a slight problem with the Levitaion Licorice," he said calmly, causing Fred to let out a loud laugh.

"What happened to that mouse you guys tested this stuff on earlier, anyway?" Brian interrupted, swimming his way through the air towards the twins.

"Well…I'd guess he's currently living his happy life on the ceiling of Hogwarts…he floated away before we could catch him."

"Brilliant," Brian muttered, earning a glare from the Weasleys.

"How about we try a spell," Fred suggested, "We can always work on an antidote for the candy later."

"Right," George agreed.

He pulled out his wand and flourished it towards Brian. "Finite!"

The spell had no effect.

"How about we try using a levitation spell on him, and then using the counter spell?" Fred asked, "It might get rid of the effects of the licorice."

Fred pulled out his own wand.

"Levioso!" He said with force, pointing his wand at Brian. The spell seemed to have no effect on the already-airborn first year. "Finite!"

"Wingardium Leviosa!"George tried, "Finite Incantatem!"

No matter what spells they tried, Brian continued floating around the room. Whenever the boy tried to swim towards the ground and land, he was unable to keep his footing. Every time he took a step, he simply began to float away again. After half an hour of trying, Fred and George sat at one of the tables and groaned.

"Lunch is about to start," George pointed out.

As if on cue, the doors of the Great Hall opened and students and teachers alike began pouring into the Great Hall. When they noticed the brown-haired first year levitating and shouting insults at the twins, everyone halted. A few students began to snicker.

Professor Flitwick stepped forward. "What is the meaning of this?" he asked Fred and George.

"We were testing our Levitation Licorice," George said.

"And it went a bit wrong," Fred continued.

Professor Flitwick sighed and waved his wand. By some unspoken spell, the charms professor was able to get Brian back on his feet again.

"To the Headmasters office, the both of you," Professor Flitwick stated.

"You two are lucky that Professor Flitwick was able to get the boy grounded again," Dumbledore said, "And you're lucky that we found that poor mouse you chose to test your candy on. Both Brian and the mouse are back where they belong, on solid ground, no thanks to you two."

"But professor, we needed to test-."

"Not on mice, and not on first years!" Dumbledore exclaimed, momentarily losing his temper, "A weeks' worth of detention for both of you! And I shall be writing your parents. I'm sure Molly would love to know that you two have been focusing more on candy than on your schoolwork."

"Yes, Professor," Fred and George said in defeat.

"However," Dumbledore said, his expression returning to calm, and his eyes twinkling once more, "If you ever perfect that Levitation Licorice, I'd love to get some. It would make dusting the corridors so much easier for the cleaning staff…"

Reviews would be amazing! :D Let me know what you think of the chapter, and who you want to see in the next chapter. :) (Remember, it can be from any generation. I plan on writing a next-gen chapter soon.)
