So it is the fortieth anniversary of one of my favorite movies this year. The Rocky Horror Picture Show always cheers me up. I know all the words to the movie and the songs. I always thought it would be cute if the gang dressed up like them for Halloween. So I wrote this... I own nothing from The Big Bang Theory or Rocky Horror Picture Show.

"This is the worst costume party I have ever been too." Sheldon grouses as he walks beside Amy to the comic book store.

"How could you possibly know that we have not even gotten to the party yet." Amy reminds him smiling.

"I hate my costume." he grumps and Amy sighs they had been bickering about the costumes all day. "You don't even look like you are in a costume except you are wearing a hat. What are we again anyways?" he says looking Amy up and down in her light pink shirt dress and pink sweater. It looks like something she would wear every day. Sheldon is just wearing is normal khakis his tan windbreaker and a pair of black rimmed glasses. Even if it is not much of departure from their normal attire the resemblance is uncanny.

"Brad and Janet from The Rocky Horror picture show. Raj and Emily are throwing a themed Halloween party at the comic book store. Everyone one is coming dressed as one of the characters."

"I have never seen that movie."

"Neither had I before Penny made me watch it when she found out Emily was having this party. It is one of Emily's favorite movies and apparently the movie is turning forty. I think we look adorable in our matching costumes."

"You would. Girls like this dopey stuff like matching costumes. If we had to go in matching costumes at least we could have picked something cool."

"I like your look like Clark Kent." she tells him knowing the compliment will sway him. he looks at her and adjusts the glasses giving her a cocky smirk.

"I always thought I would look good in glasses. However I have 20/20 vision and have never had need of them."

"Poor you." Amy says sarcastically.

"Well I guess I can respect that everyone will be sticking to the same theme. That I do enjoy."

"See silver linings." Amy tells him as they arrive at the shop and Sheldon opens the door for her and ushers her in.

"Oh my god! You guys look adorable!" Bernadette shrieks as they walk inside. She is dressed as Columbia and is wearing rainbow glitter shorts and Gold top hat her hair tucked up underneath. Howard his beside her dressed in black leather jacket with his hair greased back.

"Hey no fair." Sheldon says looking at Howard. "We all agreed to dress as a theme and you are a T-bird from Grease!" Just then Leonard and Penny walk in the store and Sheldon throws his hands up in the air. "And Penny is a french maid! Heaven's sake woman you think you could forgo the slutty costumes one year!"

"Hey! I am not a slutty french maid" Penny says angrily " I am Magenta!"

"No you are wearing all black." Sheldon says

"No , Magenta is one of the characters in the movie she wears a french maid outfit." Penny says rolling her eyes.

"I am not a T-bird! I am Eddie from the movie, you know the one played by Meatloaf?"

"How can a brick of meat act in a movie."

"Meatloaf the singer?" Howard says incredulously. "You mean you have never seen the movie?" Howard says and Sheldon shakes his head.

"Then you are in for a treat!" Emily says as she emerges from the back room with Raj. Emily is wearing a corset and underwear and garters and sparkly face is done in elaborate makeup.

"I think Emily forgot to get dressed." Sheldon intones to Amy.

"She is the main character in the movie." Amy whispers back.

"Oh the movie is about doctors? Can't be too bad then." Sheldon whispers back.

"Do you like my creation?" Emily asks grabbing Raj's arm and smiling. Raj is dressed only in a pair of gold shorts and a blonde wig.

"I already had the bronze skin for the part." Raj says flexing his arm and Emily hangs onto it an smiles at him.

"You guys all look so good!" Emily crows. "We have got Brad and Janet, Columbia and Eddie, Magenta and Riff-Raff, Dr. Frank N Furter and Rocky. I don't think we are missing anyone are we?"

"Just Dr. Scott." Stuart says wheeling out of the backroom in a wheelchair. "But that is ok I am used to being forgotten." Stuart says." Sheldon says looking importantly around the room.

"How could I forget Dr. Scott?" Emily says. "Alright I think we are ready for our special screening in the backroom. Come on Riff-Raff help me pass out the goodie bags."

"Why do I have to do it?" Leonard ask walking over to a table covered in black gift bags.

"Because Riff-Raff is my servant and it is is job."

"Why can't Rocky over there do it." he asks.

"Because Rocky is my boy toy not my servant." Emily says winking at him as they pass out the bags. Sheldon takes his bag from Leonard and looks inside and rolls his eyes.

"Not only is this the worst costume party ever they also have the worst gift bags." he says pulling out roll of toilet paper and a bag of rice and raising his eyebrow at Amy.

"It is for the movie you watch and then at different parts of the movie you use what is in the bag." Amy explains to him as he takes out a loaded squirt gun and examines it.

"How will I know which one to use when I have never seen the movie before?"

"Just look at what everyone else is doing." Amy tells him.

"Raj and his blasted penchant for interactive theater." Sheldon grumps.

"Alright everyone! Come up to my lab and see what's on the slab." Emily says walking over to the backroom door and opening it.

" There is no lab back there." Sheldon hisses at Amy.

"I see you shiver with antici..." Emily begins and the pauses for dramatic effect staring at them

"Pation!" Sheldon finishes annoyed with the pause and rolling his eyes.

"Pation... So I'll remove the cause... but not the symptom!" She says walking with a dramatic flair into the backroom.

"Raj I think your girlfriends love of showmanship rivals yours. " Sheldon tells Raj as they follow him into the backroom.

"I know she is wonderful isn't she." Raj tells him

The backroom is set up like a movie theater complete with a large screen, seats are scattered around. There is also a table set up with snacks and drinks. There is a large projector set up in the back of the room. Emily Walks up to the large screen and holds up her gift bag.

"Okay for all you Rocky Horror virgins I am going to go over the items in the gift bag. Yes Sheldon I heard you grumping." she says winking at him and blowing him a kiss. "Ok so when Ralph Hapshatt and Betsy Munroe get married you through the rice at the screen."

"Do you know that it is thought that by throwing it on the couple they will be bestowed with fertility and have many children. Also it is just urban legend that rice is harmful to birds."

"Thank you Sheldon for informing us all about that." Emily says annoyed. "Now the newspaper is for when Brad and Janet get out of the car and walk to Frank's place. Now I am really excited I got copies printed up from Nixon resignation. Since Brad and Janet re listening to a Nixon speech in the car.

"Did you know when he ran for President in 1960. He only lost to JFK by 113,000 votes in the closest election in U.S. history."

"Fascinating more interesting else you would like to tell us about Nixon before I continue?" Emily asks.

"Anymore interesting facts? Where do I begin? Bernadette you would be interested to know that he was born in a Yorba Linda California in 1913." Sheldon tells Bernadette and she sighs.

"You know what? Let's just start the movie and Sheldon can catch up." Bernadette says and Emily shakes her head in agreement.

"Alright Dr. Scott hit it!" Emily yells slapping her behind as Stuart cues the movie Emily runs to her seat as the movie stairs up and the signature pair of red lips light up the screen. Sheldon watches and listens for a while before hissing to Amy.

"Oh god… is this a musical?"

"Yes." she whispers back.

"Good like Fiddler on the Roof or bad like Annie?"

"Good… just pay attention." She whispers back and he crosses his arms and stairs at the screen. He watches for a while before rice begins being pelted at his head and he turns around to yell at his friends.

"Hey!"

"It is part of the movie experience Sheldon." Howard tells him pelting him in the face with rice. Sheldon glares at him and starts to say something but Amy grabs his leg.

"Just watch Sheldon." she says.

"It is your song! Get up there guys!" Emily says clapping them on the shoulders as the refrain to Dammit Janet starts up.

"I don't think so." Sheldon says.

"Come on Sheldon it is our moment." Amy pleads.

"I have never seen this movie." he reminds her looking at her pleading.

"Just get up there and stand with me." Amy says getting up and pulling him to his feet. He follows her reluctantly to the front of the stage. Amy puts her hands on his shoulders and looks up into his eyes."

"Oh it's nicer than Betty Munroe had" Amy sings

"Oh Brad" Everyone else choruses

"Now we're engaged and I'm so glad" Amy sings grabbing his hand as he stands there stiffly.

"Oh Brad!"

"That you've met Mum and you know Dad."

" Oh Brad!"

"I've one thing to say and that' I'm mad for you too…" she says looking up into his eyes and grabbing his hands he sighs and looks at her awkwardly. "Say Dammit Janet." she hisses.

"Amy I am not going to swear!" he tells her annoyed but she glares at him and he says reluctantly

"Dammit Janet." he says quietly crossing his arms.

"Oh Brad I'm mad!" she sings wrapping her arms around him. "I love you!" she sings and he looks around the room the dong is over he slinks back to his set.

"God I hope that was the last of it." he hisses to her as they watch the movie. Then as the movie shows Brad and Janet driving in the rain a sinking feeling invades him. "Oh god they are going to sing again aren't they?" he sighs.

"It's raining!" Emily shouts and everyone gets out there squirt guns and starts sparayng water directly at Sheldon and Amy. Sheldon grabs the newspaper out of his bag and looks back at them angrily.

"Hey!" he says.

"Good job Sheldon ! Newspaper time.!" Emily says pulling her newspaper over her head. Then she gets out her glow stick and raises it above her head. The rest of the gang follows suit and raises their glow sticks up and sings the song Over at Frankenstein Place.

As the movie continues Sheldon grumps the entire time. He's Not a fan of the. Movie and loudly points out all of its inaccuracies.

"So Emily is a woman dressed like a man dressing like a woman? Talk about your paradoxes."

"I don't care what planet they are from. Flipping on a bunch of Tesla coils and draining rainbow juice from a fish tank would not make a man! I mean the doctors name would lead you to believe that he cobbled him together from spare parts. However the man has no seams and no belly button. So we are supposed to believe that he grew him in the tank like a sea monkey?" He huffs.

"It is science fiction Sheldon you don't huff and puff about Star Wars and point how all of that is not plausible." Amy tells him.

"That's because all of that is probable! Given the right equipment and on the right dimension I could make a lightsaber. There is no dimension where you could grow a fully aged muscle bound man in in tank."

When the movie is over and Sheldon and Amy arrive back home he can tell she is upset with him. He can't fathom why she is the one upset when he was the one forced to dress in a dopey costume. Then be forced to watch one of the most confusing and strange musicals he had ever seen.

"Do you want some tea?" He asks pulling the kettle down.

"No. I am just going to go to bed." Amy says taking off her hat.

"Amy are you mad at me?" He asks her and she rolls her eyes at him. A sure sign that she is mad.

"What gave you that idea?" She asks sarcastically.

"Well your quiet demeanor on the way home, you wanting to go to bed, the way you just rolled your eyes."

"Yes Sheldon I am upset with you."

"Why? I dressed up in the stupid costume that is not really a costume. I watched the terrible movie, I participated in the silly games."

"Yes and you complained the entire time! Or pointed out everything wrong with the movie or props. The way you acted was very rude." She tells him.

"Amy you know that science is important to me. When I see that many inaccuracies it bothers me."

"I just wish you had gave the movie a better chance it was not all bad. If you had spent more time watching and less time criticizing you might of liked it."

"I paid plenty attention! There was one part I was particularly glad you were not called upon to reenact. I don't know if I could have stomached watching Raj paw all over you dressed in those gold shorts."

"Oh really? What would you have done if we had decided to act the scene out together?" Amy teases him.

"I would have been forced to act the scene out in his place." he tells her raising his eyebrow.

"I would like to see that." Amy says smiling at him.

"Do you want to reenact it right now?" he asks her biting his lip and she shakes her head yes. "Well you are over dressed, I believe Janet by this point has been stripped of most of her clothes." he says pulling off her jacket and placing it on the kitchen counter. Then he starts on the buttons on her blouse pulling it off and placing it with her jacket. Then he pulls off her skirt and she is standing in the middle of their kitchen in just her bra and slip.

"You went all out even your undergarments match your character." he says eyeing her appreciatively.

"I strive or excellence in everything I do." she tells him winking as she starts tugging off his clothes. Undressing him until he is just standing in the kitchen in his tighty whities. "Looks like you matched your undergarments to your character as well." Amy says.

"To be far I had no idea what kind of underwear he wore this is just a happy accident." he tells her pulling of his glasses but she stops him.

"No keep the glasses on I like them." she tells him putting them back on his face.

"Oh you do? Do?" he says as he leans down and kisses her pushing her against the kitchen island and attempting to lift her up.

"Uh uh, you said we were going to reenact the scene." she tells him pushing on his chest. " I was feeling done in. Couldn't win I had only ever kissed before." Amy sings softly.

"Hmm.. Brad and Janet are a fitting couple for us aren't they?" he ask and Amy shakes her head and continues on.

"I thought there was no us getting, Into heavy petting. It leads to trouble and seat wetting." Amy says blushing and Sheldon grabs her by the waist. "Now all I want to know is how to go ..I've tasted blood and I want more.I put up no resistance, I want to stay the distance. I've got an itch to scratch I need assistance." she says hitching her leg around his waist and moving his hands up to her breasts.

"I believe the next line is touch me." he hisses moving his mouth over hers and kissing her deeply. Lifting her up onto the counter. "I want to be dirty." he whispers into her ear as he trails his mouth down her neck to her collar bone. "I believe Jant tears her slip to help heal Rocky but I believe that I would like the honors" he says as he pulls up her slip and pulls of her panties. Amy pulls off his underwear and he plunges into her making her cry out. Amy wraps her arms tightly around his back kissing him as he moves in and out of her. Their glasses clink together as they kiss and Amy rips his off.

"I thought you liked them." he says smiling at her.

"They were getting in my way." she says kissing him again.

"So this was better than dancing like idiots in the back room of Stuart's comic book shop right?" he asks afterwards as they both lay together on the couch still nude.

"Oh yeah don't dream it be it." she tells him giggling.
