A/N: This fic was inspired by the movie Freaky Friday, where the mom and daughter switch bodies until they sort their shit out. It'll alternate between Mandy and Mickey's POV. The only thing I'm changing from canon up to this point (but not going forward) is that Child Protective Services hasn't take the Gallagher kids away. I'm writing this for Shameless Halloween, so I hope it isn't too weird!

Freaky Friday

Chapter 1

It all started because Mandy should have known better. Molly was staying with her at the Gallaghers' house until she could track down one of her sister's relatives. Against her better judgment, Mandy went home to pick up some old clothes that she'd outgrown so that Molly wouldn't have to keep borrowing Debbie's shit.

It was normal for the floor of their house to be covered in junk, empty bottles to be strewn across every surface and for the piles of dirty dishes to not only fill up the sink but also the kitchen counter. What wasn't normal was the smell; it was stifling. Judging from the amount of mold growing, the trash hadn't been taken out for at least a week. So, when Mandy walked into the house, sheknew that she was alone there, and she was relieved.

Mandy went to her room and started rummaging in her closet, looking for anything small enough to fit Molly. After throwing a few things into a pile on her bed, she realized she'd stupidly forgotten her backpack at Lip's. She went into Mickey's room and knelt down, looking for the old duffel bag she knew her brother kept under his bed. Mandy almost gagged from the dust, dirty clothes and actual garbage she had to move around to find the bag. How could anyone live like this?

She finally found the bag, but it was unexpectedly heavy. Something clanged around inside it. Mandy unzipped the bag and looked at the contents: there was an expensive looking bottle of dark, amber liquid, as well as a bag of weed at the bottom. Mandy took her cell phone out of her pocket and called Lip over.

While she waiting for her boyfriend to arrive, Mandy decided to air the house out. She attempted to clean a little bit and took the garbage out. Sure, it wasn't her mess, but she didn't want to remind Lip that she was associated with these pigs. There was a knock on the front door about ten minutes later.

"So what's going on?" Lip asked, curiously. He looked around the house, obviously worried that another Milkovich would be there.

"Don't worry. There's no one else here," Mandy reassured him. She turned around and started walking towards the sofa where she'd left the duffel bag. "You gotta see this," she said.

Lip closed the door behind him and walked over to where Mandy stood. He looked down into the bag and let out a whistle.

"Macallan? Wow."

"What, the whiskey?" she asked, looking at Lip.

Her boyfriend nodded, still fixated on the whiskey. He turned the bottle around, examining it. "Yeah, this bottle must be worth at least two grand. Look at the label," he said, holding it out to her. "See how it's aged? And look at the color. It's legit."

Mandy didn't know much about whiskey, and was surprised to see that Lip did. "How the hell do you know this?"

"I read a lot," he told her by way of explanation. He put the bottle down and looked at the weed. It was covered in a layer of blue powder.

"Where did you get these?" Lip asked her.

"Found them under Mickey's bed. He must have stolen the whiskey from Ian's sugar daddy's house." Mandy laughed when Lip cringed. "What, don't like thinking about that grandpa being with your brother?" she teased.

"No. I don't like thinking about him naked and spooning me while cupping my dick," he spat.

Mandy laughed and reached forward, grabbing Lip's junk. "Oh yeah? How's it feel when I do it?" She couldn't explain it, but she got a sick thrill from squeezing his balls sometimes. She liked to see how hard she could push it before Lip would beg her to stop.

Lip jumped back and out of her grasp before she could hurt him, but she proceeded to chase him. "You have nowhere to run!" she shouted after him. He turned back to look at her over his shoulder and she could see him grinning before going into her bedroom and slamming the door shut.

"Come on, Lip," Mandy taunted from outside her room. "You're gonna have to open that door eventually, especially if you want in on this weed..."

Mickey was still pissed about getting shot in his ass. He got angry every time he thought about it. Why the fuck had he let Gallagher convince him to go in the first place? It was the second time he'd gotten shot because of that stupid redhead.

He was walking home from his shift at the Kash and Grab and was looking forward to relaxing in his room with a nice glass of the whiskey he'd stolen from the good ol' doctor's house. That, in combination with the painkillers and weed he'd gotten, would hopefully numb the literal pain in his ass long enough for him to get a decent night's sleep. At least he wouldn't have to worry about his dad or his brothers bothering him—they were out on yet another run and would be gone all weekend, if not longer.

Mickey opened the door and stood frozen in the entryway. His sister was riding Lip Gallagher right in the middle of the fucking living room.

"'the fuck is going on?" Mickey shouted.

His sister and the older Gallagher recovered from the shock of being caught quickly and scrambled for some clothes. Mickey knelt to pick up Mandy's shirt and toss it to her, but he saw the open bottle of his whiskey on the floor, right beside their dad's antique tumbler. The glass was part of a pair, passed down to Terry by his father. It was one of the only things of value the Milkoviches' grandparents had brought with them when they'd moved to the States.

Mickey was furious. "You cunt! That whiskey was mine!" He picked up the bottle and the glass and slammed them onto the coffee table.

Mandy had the nerve to laugh. "Bull...shit, Mic-key!" She hiccuped while saying his name. "You know 's'well's I do tha-" she hiccuped again, "-at y'stole it!" She looked at Lip and they were both grinning like idiots. It was then that Mickey noticed how bloodshot their eyes were.

Mickey started looking around the living room. It was messier than it had been before he left for work that morning. The couch cushions were thrown about, there was a half-eaten pizza top down on the floor, and there was ash all over the coffee table and floor—actually, the ash was everywhere except inside the ashtray, where a couple of roaches were resting.

"Did you take my weed?" he demanded, sniffing the air. It reeked. He looked at Mandy but she was already sitting back down on Gallagher's lap and making out with him. "Mandy! I'm talking to you! How fucking high are you?!"

To his surprise, his sister stopped sucking Lip's face and looked at him. "Don' be jealous, Mickey... There's still a lot left." Mickey glared at her because they both knew there wasn't much left in that bottle. She stood up, presumably to offer him some, and lost her balance. Lip reached out to help her regain her balance but only managed to grab her fingertips. Mandy fell to the ground, laughing the whole way down. Mickey had never seen his sister be this sloppy before. It must have been a combination of the whiskey and the laced weed.

Mickey probably would have forgiven her if Lip hadn't chosen that moment to open his big mouth. "What's wrong, Mickey. Were you hoping to share it with someone else?" He flashed Mickey a taunting grin as he brought the other tumbler to his lips and took a slow and drawn out sip of the whiskey.

Fucking redhead had to go spill everything to his brother, didn't he... Mickey picked Lip up by his neck and threw him against the wall. The tumbler fell out of his hand and shattered on the floor; it was nothing but a wet stain and shards of glass now. "You better keep your fucking mouth shut if you know what's good for you," Mickey said, almost snarling.

Lip just laughed at Mickey's face. "Y'ain't gonna do shi-" but he didn't get to finish his sentence because Mickey punched the smart-ass right in the gut. Lip hunched over, clutching his stomach.

"You wanna try me again?" Mickey asked. He kicked Lip onto the floor for good measure.

Mickey turned around and had about two seconds before the bottle of Macallan came crashing down on the side of his head. The bottle broke and whatever whiskey had been left in it spilled all over him. "Don' touch m' boyfrien'," Mandy slurred.

Mickey swayed and it looked like he was going to pass out, but he steadied himself by putting his hand against the wall. "Bitch, are you fucking crazy?" He knew his sister was as bad as any of the Milkovich boys when it came down to it, but he hadn't expected her to flip her shit over Mickey delivering a couple of easy hits to her boyfriend.

"C'mon, Lip. Les go t' my room." She dragged Lip up by his t-shirt and led him away.

"'Ey! Where's the rest of my weed?!"

Mandy didn't answer so Mickey looked around for something to throw at her. All he saw was the half-filled tumbler he'd picked up and put on the coffee table when he'd first come in. He grabbed it and raised his arm up in the air but Mandy turned around and pointed to the kitchen table. Mickey looked over at it and saw the bag. He went into his room, taking what little was left of the weed and the whiskey with him, and pulled out a small bong from his bottom drawer. He lay in bed and held his lighter to the bong, trying not to think about how much pain he was in. He didn't know what hurt more: his throbbing ass or the headache he was now getting where the bottle had connected. With each hit Mickey took, he worried less and less about his possible concussion. The whiskey didn't even burn on the way down.

Mickey woke up and didn't know why he was in Mandy's bed. He tried to get up but had to lie back down because his head was killing him. It wasn't the type of pain one feels when they're hit over the head... This was definitely a hangover. But he'd only had half a glass of whiskey—how could he be hung over?

He closed his eyes and felt that all too familiar spinning sensation. He put a hand on the side table to keep himself grounded and rode it out as long as he could, but the need to pee was overwhelming. He got up and walked through his own room and into the bathroom, then pulled his sweatpants down and started to pee... all over himself...

Mandy woke up face down, which was weird. She didn't sleep on her stomach. She opened her eyes a sliver and realized she was in Mickey's bed. The sound of someone cursing from the bathroom was what had woken her up. If she hadn't had such a throbbing headache, she might have wondered what the hell she was doing in her brother's room instead of her own, or where Lip was, but she decided her head hurt too much to worry about anything right then.

She wanted to shrug it all off and resume sleeping until pain subsided, but Mickey burst into the room, shouting. Mandy grunted, way too conscious to go back to sleep now. She rolled onto her back to look at him but screamed from the sudden shooting pain in her ass. She opened her eyes to look at her brother, except it wasn't Mickey who was screaming at her... It was herself.

"What the fuck?!" they both screamed simultaneously.
