"Fred, you boil the newt eyes, I will cut the ginger root. Then we can add our... special ingredient," George Weasley told his twin with a michevious smile.

"Sounds like a plan, Georgie," Fred agreed, tossing the newt eyes into the cauldron with a loud BOOM! Suddenly, there were footsteps coming down the hall, stomping the ground angrily. George quickly tossed in two ingredients, and began to stir, wildly.

Their door burst open to reveal their sixteen year old brother, Percy, standing there with a beyond mad expression. "I don't know how you two never sleep, but there are other people in the house that would like to wake up before noon tomorrow! Go. To. Bed!" The redhead went to slam the door when George noticed the cauldron's contents bubbling in a suspenseful fashion.

"Um, guys, hit the deck!" With that, the concoction blew up, and although George ducked under his bed in time, Percy and Fred were a few seconds too late. The mixture of green, red, and purple splattered all over the two teenagers, and they fell to the ground, dazed.

"Ow, what the hell?" Percy's voice mumbled from the floor near the doorway. George was shocked; Percy wouldn't cuss if his life depended on it. Through the fog and steam that had clouded the room after the explosion, the more sensitive twin saw his older brother stand up, leaning against the wall.

"Watch your language!" Fred's voice snapped from the floor as he too began to stand only to slip on the spilled potion and tumble to the ground. "Ow!"

"Hahahaha!" Percy laughed, pointing at Fred through the fog. Okay, that was strange; Percy never laughed at somebody for something like that. In fact, Percy hardly laughed at all.

"Um, Perce, are you feeling alright?" George questioned, his brown eyes widened slightly in shock of his elder brother's behavior.

"Why are you calling me Percy, George? I'm Fred!" The teenager exclaimed. "Did you hit your head on the floor or something?" George slowly shook his head, his worry increasing by that second as he pointed at a mirror standing near the door.

Looking at him with a confused gaze, Percy turned to face his reflection and screamed so loudly that you could hear several bangs as their siblings and possibly their parents fell out of their beds. He turned to leave only to run into Fred, who shrieked also. The two leapt to their feet, staring at the each other more distressed than George had ever seen either one.

"Why are you me?" Percy yelled, pointing an accusing finger at his younger brother.

"I don't know! Why don't you answer that question; it was your potion, Fredrick!" Fred yelled right back.

Percy suddenly whispered, "Oh my God."

"What?"

"The ingredient, the other ingredient. George, where's that text book?"

"Wait, you two read?" Fred asked with true shock written across his face.

"Of course we read," Percy replied in a snippy, agitated voice as he tore apart their room in search of a textbook. "Where do you think we get all of our potion recipes? Ron?"

Fred nodded, deciding that that was reasonable, while biting back a laugh as he remembered the time that Ron had tried to cook and wound up nearly burning their house down. Now, his parents didn't let Ron near stoves; hell, they were nervous about him taking potions in Hogwarts.

"It's over here," George supplied, handing Percy the textbook, who began flipping through it rapidly until he came to page 319.

"Okay, here it is."

Yet before Percy could finish, the door was opened by their sleepy father. "What is all the screaming about, boys?"

"Um... Nothing!" all of the boys yelled in unison.

Yawning, Arthur waved his hand and said, "Alright, then, get to bed soon and no more explosions." With that, he walked off towards his bedroom. The three siblings looked at each other and shrugged. Well, okay then.

"Alright, so that spare ingredient George and I put in," Percy said, "is called DNA cromozone."

"DNA cromozone! That has several dangerous side effects. What is wrong with you two? Are you trying to kill somebody?" Fred snapped, quietly.

"No, it was just an experiment. Now, here's what the paragraph says. The use of DNA cromozone can cause several problems within the body, but most are reversable. The side effects of DNA cromozone use are a change in personality and/or physical appearance, mental disorders, particularly multi personality disorder, bipolar disorder, or schizophrenia, or disease. Some of these diseases/health issues include leukemia, brain cancer, and high blood pressure. In extreme cases, a person may suffer amnesia or switch bodies with another person. People rarely die from the use of the product, but rather die from the aftermath."

"So, wait a minute," George broke in. "Are you saying that you two switched bodies?!"

Percy and Fred nodded.

"No way."

"Come on, George ask me something only Fred would know," Percy (or was it Fred?) told his brother.

"Fine, what do I want to name my future kids?"

"For a girl, Roxanne, and for a boy, you wanted to name him Caleb until you lost a bet with me and now, you have to name your son Fred."

"Did you two really make a bet like that?"

"Don't you know us, Perce? We've made hundreds!"

"Should've known."

"Wait!" Percy- no, Fred!- gasped. "It's says here that if two people were to switch bodies, there's an experimental potion to reverse it, but it's never been tested, therefore no one knows what will happen because of it, if anything at all. And on top of that, the potion take at least 4 MONTHS to brew!"

"4 months? You've gotta be kidding me!" George complained, collapsing onto his bed.

"Look, we can pull this off. No offense but I think all three of us here know that out family and friends aren't the most observant people. It's the professors at Hogwarts that we have to worry about because if they notice something off, they'll tell Dumbledore and he'll tell Mum and Dad," Percy in Fred's body reassured them

The other two nodded, still not totally convinced. "Okay, so here's the plan..."
