My friend and I were reading Puck and Sabrina fanfics from the book series The Sisters Grimm and we were thinking it would be hilarious if they switched bodies.

They live in a world of magic and fairytales, so that wouldn't be too out of the ordinary, but it got me thinking…

How come that has not been an AATC episode?

Hahah to prove it could have been, I'm writing this xD

(It's the 80's version, and they're 10 yrs old or whatever they are in the cartoon)

"Alvin, shut up! I'm trying to concentrate here!"

"Loosen up, Simon," Alvin said cooly, "I get B's all the time." There was a pause. "Actually, I hardly ever get B's, but when I do you don't see me getting all dramatic!"

"Yeah, well, this isn't about you, Al-vin." Simon pointed in Alvin's direction and slowly walked toward him as he spoke. "It's about me, and how hard I worked on that self-cooking hotdog container for science, and forgetting to explain my hypothesis, and getting a…a…." Alvin's back hit the basement wall and Simon's finger touched his nose. "…A B!"

Simon looked away as if he couldn't bear speaking his situation aloud. Alvin pushed Simon's finger away and put a hand on his back. "Aw, it's OK Simon, I—"

Simon swiftly walked away, cutting Alvin off. "You're darn right it's OK, because I'm going to make sure I get what I deserve!" He stopped at his lab table, took off his glasses, and lifted some stiff, metal goggles. He turned and walked back to Alvin. "You see, I've taken the technology I used to develop the hotdog cooker and intensified it 50 times." He traced his finger around the ring of metal then pointed at the lenses. "When it automatically locks target, the wiring in here produces heat, which is emitted through the eye-holes of the wearer and transfers through the skin and into the body of the two—it only has enough energy for two—people in the wearer's line of sight. This way the hydrogen and carbon molecules will increase in speed, releasing themselves into the air and, well, searching for a new home, if you will. Once they sink beneath the skin of the new host, they create compounds similar to the party they previously inhabited, and voila, a body-switch!"

Alvin stared at him. "All I heard was 'body-switch,'" he admitted easily, "and I have a question. Why not just go into her computer after school and change it if you were going to go through all the trouble of making—" he poked the metal specs "—this thingy?"

Simon was taken aback. "Are you kidding? That's at least against the rules, if not illegal!"

Alvin rolled his eyes. "Right. I forgot that there's no law against…whatever it is that you're…doing…."

Simon nodded curtly and squeezed his head into the shape-hardened goggles. "Now for a test run. THEODORE!"

"A test run?" Alvin asked. "You haven't tested these yet?"

"I just started building them when we got home from school," Simon said. "How long do you think I've known about my grade?"

"Well, she posted the grades online, like, three weeks ago…so…."

He could see Simon's eyes through the thick black glass widen a little in frustration, but he quickly shook his head. "Never mind that. I have these ready and that's all that matters."

Just then Theodore burst through the basement door and ran down the steps. "Is everything alright?" he asked worriedly. Alvin looked at him. "I always get nervous when Simon yells," he explained.

"I'm fine, Theo, thanks," Simon said and explained the situation again.

"You do realize you could just talk to her," Theodore mentioned.

"Yeah, there are other ways to get through this," Alvin added, surprisingly encouraging.

"No! I'm the smart one, and we're doing things my way! Now stand together!"

"Whoa whoa whoa, hold up," Alvin said. "Are we your lab rats?"

Simon looked at him. "I won't beat around the bush. Yes. A responsible figure needs to be able to handle the situation properly and make things right if something goes wrong. Now come on! I want to get this over with so I can determine whether or not to make this an all-night project!"

"I'm not going to be part of this. I refuse to!"

"Alvin, please—"

"Alvin, Alvin!" Brittany suddenly burst through the door and ran to Alvin, tackling him over. She stood right back up and looked down at his face. "Guess what I got on my hotdog cooker thingy!"

"Was yours the one with fake diamonds on the side?" Alvin said unenthusiastically, getting back up.

"Sure was!" she said proudly. "Now guess!"

"Alvin, come on. Can we please get back to this?" Simon tried to interject while looking toward Theodore so as not to lock target, but he was ignored.

"Uh…a C minus."

"Nope!" Brittany giggled. Alvin smiled a little. "Guess again!"

"C plus?"

"I swear, Alvin, if you don't get over here right—"

"An A plus!" Brittany squealed and jumped in the air.

"WHAT?" Simon's head jerked to where Brittany was. Which was a big mistake, because the goggles locked target.

"Wait, why are you telling me?"

"Because I needed someone to brag to." Neither of them seemed to hear the small noise emitting from the eyewear as it began to heat, then transfer to the lenses.

"Uh, guys?" Simon tried.

Brittany started to leave. "You know the grades were posted, like, three weeks ago, right?" Alvin said.

She stopped walking. "Are you serious? I've been waiting for my grade for, like, months!"

"Guys?"

Alvin laughed. "What's so funny?" Brittany said, slightly hostile. "I bet you didn't get a grade half as good as mine!"

"No," Alvin said, "It's just that you and Simon both—"

"YOU GUYS!"

"What?" They said simultaneously. At that moment, two slim, purple beams shot from Simon's eyes and engulfed the pair in a feeling of extreme heat. They cried out in shock, doubling over.

The process had only lasted five seconds tops, but it was a blast of nearly 200 degrees Fahrenheit, and although their outer and inner delicacies were not directly affected, both bodies had felt a passing wave of heat as the beam entered and exited.

Simon struggled out of the metal headgear, and Theodore, who was politely silent the entire time, now rushed to help them up.

"Are you OK?" Theodore asked, lifting Brittany to her feet.

Simon stood nearby, privately examining the results.

Alvin still remained crouched on the floor, but looked to Simon and said, "Well, don't just stand there! Be a gentleman and help me up!*"

Simon stepped away from Alvin's outstretched hand. "I'm sorry, what?"

Alvin looked at his hand. "Omigosh—where did I get this beautiful tan?" He smiled and brought it closer to his face, examining it. "Wait…why am I wearing a red sweater…why am I wearing Alvin's sweater…?"

Brittany finally took a look around and stared at Alvin. "And why am I looking at myself when there's no mirror here?"

Simon did a little dance. "It worked! It worked! Now all I've got to do it take this baby to school and—"

"Forget that!" Alvin reached out and took hold of Simon's shirt, swatting the goggles out of his hand; luckily, Theodore was on hand to catch them. "CHANGE. ME. BACK."

"Me too!" Brittany added. "Or I'll…I swear I'll…um…kiss you!"

"Not if I do it first!"

"You guys!" Simon backed away from them. "You don't have to threaten me. The solution to this problem is much simpler than you'd think. All I have to do is look at you through my invention again and you'll be back in your own bodies."

"Then do it!" they both shouted and stepped back.

At that moment, there was a knock at the basement door. "Are you guys alright in there? I always get nervous when Simon yells."

Brittany—who was really Alvin—gasped. "It's Dave!"

"I'll get it!" Theodore offered in an extremely chipper voice and ran to the door faster than anyone could protest.

"We'll have to do it later," Simon murmured, coming in between Alvin and Brittany's heads.

Dave walked in. "Thanks, Theodore. What was going on down here?"

"Nothing, Dave!" Simon was quick to say. "I was just telling them how I recently received a B on a science project." He flinched. "No big deal."

Brittany elbowed Simon lightly and whispered. "That's what I've been saying."

"You've been saying what, Brittany?" Dave inquired.

Brittany stood straight up. "Oh…um…hee-hee," she said and over-dramatically tossed her hair.

Alvin glared at her. "I do not do that!" he yelled, putting his hands on his hips.

"Don't you dare put my hands on my hips again!" She turned to face him.

"Or else what? I can do whatever I want." He walked in circles, swinging his hips side to side.

Brittany was horrified. "Or else I'll…I'll…do this!" She began to scratch her butt in full-view of everyone. Alvin stopped dead.

"Stop it!" he whined. "That's disgusting! Do you realize how long it took me to do my nails?" Alvin shoved Brittany and sent her stumbling backward into Dave.

"Whoa, whoa, whoa, calm down now, you guys," Dave said, confused and a little nervous.

"You can't shove a girl!" Brittany protested and shoved back.

"Come on, that's enough!" Dave grabbed Alvin's wrist and began to drag him back upstairs. "I've got some chores from yesterday for you to finish."

His eyes widened. "But—but Dave, I…." He looked pleadingly from Simon to Brittany. "I—I can't! I have to—"

"—Clean your room, finish the dishes, vacuum the living room." Dave finished.

Alvin pointed a finger menacingly at Brittany just before he disappeared over the doorframe. The door shut.

Brittany burst out laughing. "That sucker! I totally got out of all those stupid chores! I never want to change back!" Alvin spun around and twirled in his new body.

Simon pinched the bridge of his nose. "Uh-huh…listen, you should probably get back home."

"Home?"

"I'm not sure what Brittany told her family when she left the house, and we don't want to arouse unnecessary suspicion."

"Oh…." Brittany thought for a bit. "Oh yeah…I'm Brittany now." She gave herself a once over. "I'm a girl now." Her face scrunched up as the thought of using the bathroom crossed her mind. "See you guys later…I guess…." She turned to go.

"Don't worry, Alvin!" Theodore called out as Brittany opened the door to leave. "Simon'll have you back to normal before you know it!"

*Yeah, yeah, whatever, I used that quote in another of my stories, so what xD

I don't really enjoy cutting up one-shots to make chapters, but I've got so many ideas and I'm already halfway through chapter 2 so I think this would be a nice ending to the first chapter hahah

Three chapters, tops. I promise. (:
