A/N: NEW STORY! And it's gonna be quite interesting. Oh, you'll see.

I also don't own Freaky Friday, whose idea is similar to this one.

iSwitch

Prologue

"Will it cause the sky to rain candy?!"

"No."

"Attack Freddie!?"

"No!"

"Fly us to a planet full of friendly, ham-eating aliens who love to share?"

"Sam, aliens don't eat ham!" the brunette iCarly star exclaimed.

"And how would you know?!" Sam Puckett shot back quickly. The two friends were sitting in the Shay's small apartment kitchen, creatively discussing Carly's latest iCarly suggestion.

"Alien's don't even exist!"

"That's negativity!" Sam pointed out. "Look, all I'm saying is, usually when we put something invented or touched by Spencer on our show, expecting something good to happen, it either bursts into flames or nearly takes off our heads!"

"Not true." Carly crossed her arms. She wasn't going to give in that easily. Spencer's happiness was important to her.

"Oh yeah?!" Sam smirked. "Remember his wheel of hammers?"

"That was an accident!"

"…and his mechanical monkey?"

"That only burst into flames one time!" Carly argued.

"Twice!"

"Fine." Carly sighed. "Listen, it's just really important to him. He wants to show the world his new genius invention."

"What is it, even?" Sam asked.

"It's supposed to read your brain waves or something and send out your favorite flavor of frozen yogurt." Sam raised an eyebrow. "Oh, come on, like that doesn't sound cool."

"Alright, alright." Sam gave in, annoyed. "We'll have him show his invention at the end of iCarly today."

"Yay." Carly smiled.

"But if anything bad happens," Sam tells her. "It's on your shoulders, Carly Shay."

"Fair enough!" Carly said happily, then turned towards the stairs. "Spencer!"

-Crash- "What?!"

"I'm gonna go tell Spencer, okay?" Carly said to Sam. "If Freddie gets here, tell him –"

"That he's a nerd? Why certainly!" Sam finished enthusiastically. Carly sighed.

"Why do I even try?" She gave Sam a look reserved only for her Freddie insult, and then headed up the stairs, after hearing another crash. Sam, meanwhile, was hoping that those crashes had nothing to do with his frozen yogurt machine.

Sam never understood why Carly got so annoyed by her arguments with the dork. It wasn't like they were so out of the blue. She and Freddie were just so different – different school expectations and cares, different socially (as in, he was a loser, and she wasn't), different eating habits, different favorite foods and drinks and colors, different moms, different attitudes, different… everything. So of course Sam was prone to arguing with him. There was a heck of a lot to argue about.

A loud yelp from across the hall broke her from her thoughts.

"Fredward, wait!" a screeching voice similar to that of an angered monkey called out. "You forgot your ointment!"

"Mom, I don't need ointment!"

"Don't lie to me!"

"Bye mom!" And in a flash, Freddie Benson was inside the Shay's apartment, the door slammed, panting like a tired runner.

Sam raised an eyebrow and smirked. "Ointment?"

"Don't say a word." He mumbled, pulling himself off the door.

"You're right, it's too easy." She shrugged.

"It is so annoying to live with," he sighed. "You don't even know."

"Please," Sam rolled her eyes. "Try having my mom. It ain't pleasant. If I were you, I'd set your mom straight in less than five minutes."

"Oh, you think it's so easy to be me?" he asked, annoyed. "You wouldn't last one day!"

"Well, you'd probably be dead in three seconds if you were me." Sam shot back.

"Wanna bet?"

"We can't, moron." Sam rolled her eyes again. "There's no humanely possible way to switch bodies. You, being a dork, should know that." Freddie was about to retort when Carly stepped between the two bickering teens.

"Enough!" she said, fed up. "Let's please just go upstairs and do iCarly before my co-host or techie ends up unconscious!"

"Whatever." Freddie said, glaring at Sam.

"Whatevs!" Sam yelled back, shooting him a similar glare. The three friends then headed upstairs.

"And that," Sam ended the segment that she and Carly liked to call 'Bananas Dressed Up Like Circus Freaks.' "Is what a bearded banana might look like!"

Carly applauded as Sam hit her remote. "Okay guys, to end the show, we've got a big surprise."

"That hopefully won't set anything on fire!" Sam said energetically with a smile. Carly nudged her in the side. "Ow!" Freddie laughed from behind the camera, but then he remembered that he was supposed to be mad and his smile faded.

"Anyway, please welcome my brother Spencer – "

"The guy with the crazy socks!"

"And his invention!" Sam hit her remote and cheering came out as Spencer and his gadget emerged from the elevator. His invention was tall, silver and oval shaped, a circular window in the middle filled with what looked like twenty or so flavors of frozen yogurt, and some cups. Attached to each side were two large tubes with colorful helmets attached to the ends, with a bunch of wires attached. A tray was attached to the bottom of the window, under an opening in the window where, they guessed, the frozen yogurt would come out.

"Is that Miss Briggs?" Sam asked, laughing. Carly laughed, and Spencer finished rolling his machine in.

"So Spence, tell us what this thing does!" Carly said to her brother.

"My pleasure, Carly!" Spencer said boldly and loudly, as if he had to scream for the world to hear him. "This – " he gestured dramatically to the machine. "Is called the Yogurtinator."

"Clever." Sam said dryly. Spencer ignored her.

"With the simple addition to your head of one of these helmets, the Yogurtinator will read your mind, yes, read it like a book, and spit out, though not literally, your favorite frozen yogurt flavor!"

"Cool!" Carly said with a smile, pretending she hadn't heard this before.

"Awesome!" Freddie added. "How did you make it?"

"I have no idea!" he yelled. "But it works!"

"Let's see then." Sam said. "Carly?" She handed Carly one of the helmets. She suddenly looked nervous, and Sam smirked and gave her a look that said 'this was your idea, Carly. You suffer the consequences.'

Carly put the helmet on her head and fastened herself in. Spencer smiled goofily.

"Here we go!" he shouted excitedly, and pushed a few buttons. "Now concentrate on your favorite ice cream, Carly. Concentrate."

Everyone watched in awe as the machine began to sputter and hum wildly. Lights on top of it that no one had noticed before began to flicker randomly. Carly closed her eyes, and then, all of a sudden, a cup full of yogurt popped out through the opening in the window and onto the tray. The machine made a ding noise.

Carly took off the helmet slowly, and they all watched as she walked over to the cup, grabbed a spoon, and popped a small amount of the frozen treat into her mouth.

"Strawberry." She said to her friends and the viewers. "It's strawberry. That's my favorite flavor."

"Told you! Told you!" Spencer started hopping up and down. "I knew it worked!"

"Can you believe this?!" Sam said to Freddie's camera. "I sure can't!"

"Me either!" Freddie agreed. Sam's eyes narrowed.

"I wasn't talking to you, dork." She snapped. "I was talking to the viewers."

"Lucky them." He said sarcastically.

"What was that, Fredward?!" They continued to argue while Carly and Spencer stared awkwardly.

"It's gotten so much worse lately, their arguing." Carly whispered to Spencer, so only he could hear. "Any ideas?"

"Well, the yogurt machine can do two people at the same rime," Spencer suggested. "So maybe they can do that to stop argu – "

"Okay you two." Carly said smiling, and she grabbed her two friends, took the camera from Freddie and handed it to Spencer. "We're going to see if it works with two people now!"

Sam groaned. "But – "

"Helmets on." Carly commanded.

Freddie added in. "But I don't want – "

"Helmets on!" she handed both of them the separate helmets and they grudgingly placed them on their heads and fastened themselves in. Carly grinned. "Are you guys ready?"

"No." Freddie said, bored.

"Yay." Sam said sarcastically.

"Good! Spencer, do it!"

"Doing it!" he yelled and pushed a couple buttons. The tray under the opening now split into two trays. "Now guys, think hard about your favorite ice cream flavor."

Chocolate. Sam thought, annoyed. Ugh, I can't believe Freddie. He thinks his life is sooo hard. He's such a nerd, I can't stand him!

Vanilla. Freddie was thinking. I can't believe Sam thinks she's got all the problems. She makes me so angry…

Suddenly, the machine started to shake and sputter and the lights flickered, more so than before. It looked like it was working until suddenly, it went out of control. Smoke started coming out of the machine, a thick, white smoke, and sparks flew from the top.

"Uh, I think something's wrong!" Spencer shouted over the noise.

"Guys, take the helmets off!" Carly yelled. Freddie and Sam took the helmets off a in panic and threw away across the floor, and backed away. Just as that happened, both helmets caught on fire and the machine stopped whirring. It made the ding noise again, and the lights at the top completely turned off.

Sam looked over at the flaming helmets, and then at Carly. "I told you so."

Spencer ran for the fire extinguisher (at this point, he could find that thing with his eyes closed), and quickly put out the two fires before they set off the alarm, all the while still holding the camera. Then he sighed.

"I guess it didn't work." He said sadly.

"Nooo, I thought it did." Sam added, with sarcasm.

Then, out of nowhere, two cups of frozen yogurt popped out of the broken machine. Startled, Sam and Freddie walked over.

"The machine got mine wrong." Freddie stated when he saw the cup of yogurt on what was supposed to be his tray. "This is chocolate."

"Yeah, and mine's vanilla." Sam added. "It was supposed to be chocolate."

"Weird, they must've mixed them up." Carly said. "Oh well, it's broken anyway."

Sam took a bite of Freddie's chocolate yogurt. "And at least the yogurt is good!"

"Hey, that's mine!" Freddie protested.

"Oh, just quit whining and eat my vanilla!" Freddie mumbled something to himself and took Sam's vanilla yogurt.

"Well, that wraps up iCarly for today." Carly told the viewers with a shrug. "I'm Carly."

"I'm Sam!" Sam said, with her mouth full of chocolate ice cream.

"I'm Freddie." Freddie added brightly. Spencer turned the camera to himself.

"And I'm a fai-heh-heh-heh-lure!" he wailed.

"And?" Carly urged him.

"And this is iCarly!" he cried, in his famous upset shriek.

Another episode done. Little did Sam and Freddie know just what it caused.

It was night time, and two teenagers who often fought were fast asleep. Freddie, in his own apartment and bed, and Sam, who was sleeping over at Carly's, as usual.

Sam was snoring lightly, wrapped in a blanket on the Shay's couch. She looked as if she was having a troubling dream. Her best friend Carly was on the other side of the couch, leaning on a pillow, dreaming.

And all of a sudden, Sam's body started to glow a mysterious white color. It seemed to rise, the color, and get whiter and whiter. Slowly, the white fog slipped completely off of Sam and drifted towards the door of the apartment, and then right through it.

Outside the apartment room, the mysterious white fog drifted into the center of the hallway, where but another white fog was waiting. This fog came from Freddie.

As soon as the two fogs touched, at the speed of light, they both zipped in the opposite direction of their source bodies. Sam's fog flew through the Benson's apartment, searching until it found its way to Freddie's room. Slowly, oh so slowly, it sank into Freddie's body. Freddie's fog, at the same time, soared to where Sam was sleeping and disappeared inside her.

Tomorrow was most definitely going to be an interesting day. Because now, the bet was on.

A/N: This is a new story idea I had. I was going to release it after I got back from vacation (I leave the 16th), along with another crossover story, but for some reason, I felt like putting it up, in case someone else came up with the idea.

Oh by the way, I'm aware the mirell has a story out, called iSwitched Bodies, but it's about Sam and CARLY switching, and seems like it is very different from my story. So I am in NO WAY stealing their writing or story. I would never in a million years do that. I just wanted to make that clear.

Anyway, I hope you like it! From now on, each chapter will switch between Sam and Freddie's POV.
