Extended Plot
Howard receives word from NASA that his mission to the International Space Station has been cancelled due to problems with the Soyuz capsule during pressurization test. He seems quite relieved about not going into or possibly dying in space.Later on, at the tuxedo store, as the guys are getting fitted into their tuxedos, Howard breaks the news about his mission's cancellation to Leonard and Raj. The two men express their relief that Howard is not going since they find Russian technologies to be unreliable. Sheldon comes out from the fitting room, wearing a tuxedo with a red long john. Leonard thinks he must be burning up with all the layer of clothings but Sheldon defends wearing the long john to protect his urethras. He looks pleased with his appearance in front of the mirror but upon discovering a used tissue inside one of the pockets, he starts to freak out and ran outside to get emergency Purell from Leonard's car.

Meanwhile, at Penny's apartment, Leonard comes over carrying a small cylinder containing sulfur hexaflouride gas, which is a leftover from one of his experiments at work. He brings over a balloon and the two of them start to play around by inhaling the gas and laugh as their voices change. This eventually leads to them making out. Penny then tells Leonard that she is ready if they want to take their relationship a little bit further by having sex. She also stresses out how much she does not want to make things weird between them if they do. Leonard agrees and they continue making out.

At Amy's apartment, she is making dinner when Sheldon knocks on the door with his trademark triple-knocks. It is their monthly date night. Sheldon is perplexed as to why they are spending their date night at her place when the Pasadena City Council is considering making crosswalk time longer and the lego store is having a Midnight Madness Sale. He thinks having adequate time crossing the road to walk to the lego store to get a lego Indiana Jones is the idea of a hot date. Amy thinks since all their friends are making progress in their relationships, they should. Sheldon disagrees, because he has known her for two years and he is already at her house after dark, so they cannot go faster than that. Amy knows that he will be reluctant which is why she is using her knowledge in neurobiology to increase his feelings for her. She says that human beings develop emotional attachments and in Sheldon's case, his attachments include his mother and superheroes, so she will try to transfer those attachments to her. She starts by turning on a romantic music, which turns out to be Super Mario Bros. Theme tune, Sheldon's favorite from his childhood days. Sheldon sees where she is going and notes that it is not going to work, although he starts to hum along with the tune. Amysmiles and moves on to her second plan, offering him a drink. He tells her he does not drink but changes his mind when Amy offers him strawberry Quik, his favorite pink fluid. Amy proceeds by telling him he will be surprised at what she has prepared for dinner, which turns out to be spaghetti with hot dogs cut up in it, another of Sheldon's favorite. Sheldon is ecstatic and starts scooping spaghetti onto his plate, while commenting that they should do this more often. He suddenly stops as he comes to a realization at how Amy's gestures cause him to react, only to earn a wide grin from Amy.

Back at Penny's apartment, Penny and Leonard walks out of her room, with an extremely upset Penny. She does not appreciate that Leonard proposed to her in the middle of sex, but Leonard reasons that he was just caught up in the moment, and also, since Howard is getting married, he is having some kind of a wedding fever. He tells her that when they look back at this one day, it is going to be funny, and proceeds to imagine a flashback of the moment. Penny does not think it is funny and is upset that Leonard is moving too fast again. After failing to make Penny laugh at their situation, Leonard takes it as a cue for him to leave.

Meanwhile, in Howard's room, Howard suggests to Bernadette that they learn the final dance routine from Dirty Dancing for their first dance, although he will be the girl and Bernadette the guy. Bernadette says that Howard is in a good mood, and he is, the effect of not having to go to space, but he reasons that he is just happy he is marrying the girl of his dreams and his mother has agreed to not follow them on their honeymoon. Suddenly, NASA calls and informs him that the mission is back on, though his launch date will be pushed up to the same week as his wedding. Howard tells Bernadette this, in the hope of getting her upset and he will have to cancel the mission then. Surprisingly, Bernadette is happy for Howard and wants him to pursue his dream, even at the expense of postponing their wedding. Howard tries using every excuse not to go and tries to get Bernadette to change her mind by mentioning her intimidating father, who will lose the deposit he paid if they postpone their wedding, but Bernadette is convinced her father will be fine if she talks to him. So, Howard volunteers to talk to him himself, and seems excited when Bernadette thinks Howard meeting her father will only cause him to make Howard cancel the mission, though he conceals it.

At Sheldon and Leonard's apartment, the two friends are playing 3D chess. Sheldon moves his Queen to the second level. Leonard uses his Knight to take out Sheldon's Bishop and wonders whether Sheldon is fine since his last move leaves his Queen vulnerable, and before that he moved his Knight to a corner, trapping it, and he keeps sighing "Why me?". He sighs and wonders whether he can ask Leonard about women. Leonard tells him to read the book he got him last year. Sheldon refuses and says that he is having a problem with Amy and that the book gave him nightmares. Leonard tells Sheldon that he too is having problems with Penny. Sheldon is amazed that the two of them are engaging in the social convention of men talking about their ladies. He tells Leonard that Amy has embarked on a campaign to increase his feelings for her by making him happy. Leonard sarcastically responds with how awful that must be for Sheldon. Sheldon continues by telling that Amy has arranged for him to become an Amtrak junior conductor for a day, which is supposedly open for children only, but she got them to make him an exception. He even gets to blow the whistle. Leonard admits that Amy is good. Sheldon agrees and continues that his condition worsens because he starts to have affectionate feelings for her at inappropriate times. Leonard mistakes his words for carnal desires and Sheldon quickly negates him, and tells him to stop referencing that book he got him. Sheldon tells that he starts seeing particles from his work as Amy's dandruff gently cascading down her pale and slightly hunched shoulders. He wonders what has Amy done to him, and how to make those feelings stop. Leonard suggests proposing in the middle of love-making if they have gone physical as it is guaranteed to kill the mood, as he has done with Penny. Sheldon assumes they are discussing about Leonard now, and wonders whether all they do is complain about their ladies but no one offers any solutions. Leonard tells him it is, and Sheldon complains no wonder the women are winning.

Howard is at Bernadette's father's house. He is looking at an album and Howard is shocked to discover it is a picture of dead people. Mr Rostenkowski tells him it is a picture of his last murder case. Howard is uncomfortable and starts telling him about his mission and the wedding postponement. He gets even more intimidated when Mr Rostenkowski uses that time to crush walnuts. Howard quickly wraps up their conversation by saying that he understands they cannot postpone the wedding so he will cancel his mission and proceeds to leave the room. Mr Rostenkowski stops him and tells Howard that he initially did not think Howard is the right man for his little girl. He even thought that Bernadette chooses Howard to purposely punish him, until he heard about Howard going to space. Howard tries to come up with excuses to get Mr Rostenkowski make him cancel the mission but he says not to worry about the deposit. Howard finally confesses that he is terrified about going to space. Mr Rostenkowski comforts him by saying that everything will be fine and that Bernadette can always find someone else if he does not come back.

Leonard walks up the stairs and reaches his apartment, at the same time as Penny is leaving hers to go to work. She greets him and proceeds to go down the stairs. Leonard stops her and brings back up the topic of his proposal. He tells her she has not answered him. She knows. He asks her again to answer him, so Penny walks

up to him and gives him a kiss. Immediately upon breaking apart, she tells him no. She continues walking down the stairs and Leonard asks her out loud whether they are still dating though and she answers yes. Leonard is happy, and proceeds to enter his apartment. He is shock to discover Amy wearing an Original Series Star Trek medical uniform, using a medical scanner and a tricorder, as she performs check-up on Sheldon, who is lying flat on his back on the couch. Amy greets Leonard and he asks her what they are doing. Amy tells him that they are playing Doctor, Star Trek style and winks at him. Sheldon tells Leonard that he is in hell, but then tells Amy to continue what she is doing.

Quotes
Sheldon: Amy has embarked on a campaign to increase my feelings for her, by making me happy.

Sheldon: ''I must say, I was surprised you chose to spend our Date Night in your apartment. As I mentioned, the Pasadena City Council is debating longer crosswalk times, and later the lego store is having a Midnight Madness Sale. You ask anyone, that's a hot date.''

Amy: Tempting choices but, I have something special planned for tonight.

Sheldon: What can be more special than having an adequate amount of time to cross the street on your way to buy a tiny Lego Indiana Jones?

Amy: With our friends moving forward in their relationships, I have decided that we should make progress in ours as well.

Sheldon:'' Dear Lord! Two years ago we didn't even know each other. And now, I'm in your apartment after dark. How much faster can this thing go? ''

Amy: I had a feeling you'd be reluctant which is why I'm going to dip into my neurobiological bag of tricks.

Sheldon: ''Oh! You brain monkeys kill me. Dip away''! (Takes a seat by the counter)

Amy: ''I've devised an experiment that I believe will increase your feelings for me, in an accelerated time frame. ''

Sheldon: ''Well, how do you propose to do that? I hope you're not thinking about some sort of LSD thought control. Because there's only one mind-expanding drug that this man enjoys, and that's called school.''

Amy: (Opens her refrigerator) ''Human beings form emotional attachments as they grow up. In your case, to your mother, superheroes, etc. I'm going to attempt an experiment that will get you to transfer those feelings to me.''

Sheldon: Well, seems what's on the menu tonight is malarkey, with a big side of poppycock.

Amy: ''We'll see. Let's start with a little romantic dinner music, shall we?'' (turns on the music)

Sheldon: ''Super Mario Bros. theme? ''

Amy: Yes.

Sheldon:'' I see what you're doing. You're attempting to build on the work of Ebbinghaus by triggering an involuntary memory of me playing that game. Admittedly the happiest 600 hours of my childhood. But it won't work!''

Amy:'' Fine! There's no reason we still can't have a lovely dinner. Why don't you have a seat. ''

(Sheldon walks to the set-up table while humming to the Super Mario Bros. theme)

Amy: May I offer you something to drink?

Sheldon: You know I don't drink.

Amy: Not even, (takes out a bottle) strawberry Quik?

Sheldon: ''I love strawberry Quik. It's my favorite pink fluid. Narrowly beating up Pepto-Bismol.''

Amy: ''Oh, I know. I think it will go nicely with what I have prepared for dinner. ''

Sheldon: (Pleasantly surprised) ''Spaghetti with little pieces of hot dog cut up in it! ''

Amy: Just like your mommy used to make.

Sheldon: ''Oh! Yummy yummy! (scoops spaghetti on his plate) We should do this more often. (Realizes something) Uh-oh!''

Howard: ''Well, that's it. My orders have been rescinded. I am officially no-go to space.''

Leonard: ''I'm sorry, Howard. But I gotta tell you, I'm a little relieved you're not going.''

Howard: Why?

Leonard: Come on, you were gonna go up in a rocket designed in the 1960s by the Russians.

Howard: Yeah, so?

Leonard: When was the last time you were at Best Buy and you heard someone say, "Ooh, check out this Blu-Ray player, it must be good, it was built in Russia."?

Howard: Well, their technology isn't that bad.

Raj:'' When you come back to Earth in a Soyuz capsule, you free fall, from space, at 500 mph, and the only thing that slows you down is a little parachute that pops out right before you crash into the ground. And the whole thing was designed by the same brilliant minds who were unable to capture Rocky and Bullwinkle.''

Howard: ''Right, well, whatever. I wasn't worried.''

Raj: You weren't?

Howard: ''Let me explain the difference between you and me. You watch Star Trek, I live it. ''

Raj:'' Oh, please. I don't remember the episode of Star Trek, where the guy never goes to space, and brags about it in a tuxedo store.''

Howard: Make all the jokes you want, but there's only one of us here brave enough to almost do what I almost did.

(Sheldon comes out from the dressing room, he wears a red long john with the tuxedo he is wearing)

Sheldon: ''Ah, much better! ''

Leonard: You must be burning up.

Sheldon:'' A little. But not more than your urethras will be after whatever's in those pants swims up them. (Looks in a mirror) Well, I cut quite the dashing yet hygienic figure, don't I? I look like The Flash, about to get married. (Puts his hands in the pockets, and discovers a tissue in one of them) Oh, a tissue! A tissue! Oh, good Lord! ''(Runs outside)

Tuxedo store staff: Uh, where is he going?

Leonard: ''He keeps emergency Purell in the car. (Fishes out the car key from his pocket)''

Sheldon:'' (Runs back in) Keys! Keys! Keys! (Grabs them from Leonard and runs outside again)''

Trivia

 * A botched pressure test of the real Russian space capsule slated to launch the next crew to the International Space Station forced NASA and its partners to delay the planned liftoff for more than a month. The Soyuz's crew capsule, one of three modules that make up the entire Soyuz TMA-04M vehicle, had been scrapped after an accident during testing caused it to spring a leak in one of its descent module's rocket thruster fuel tanks. (See the article Damaged Russian Spaceship Forces Big Launch Delay for Next Station Crew.)
 * Mr Rostenkowski (played by Casey Sander) is introduced in this episode.
 * This is the first time that a reference is made about The Rocky and Bullwinkle Show, after the famous animated series. Raj is wrong because Boris and Natasha were spies for the fictional nation of Pottsylvania and not the Soviet Union or Russia. But then again, Raj was only joking.
 * An allusion to Dr. Seuss' How the Grinch Stole Christmas! is made, with previous references in The Classified Materials Turbulence and The Maternal Congruence.
 * Sheldon spent 600 hours of his childhood playing Super Mario Brothers.
 * Mr. Rostenkowski has a cupboard full of shotguns.
 * Leonard wins the three-dimensional chess match against a distracted Sheldon.
 * Raj comments on how Sheldon is wearing full body underwear to avoid germs isn't as entertaining as when he rents bowling shoes. He's referring to Sheldon's custom to spray his bowling shoes with disinfectant, a sight that was seen in The Wheaton Recurrence.
 * Amy prepares spaghetti with little pieces of hot dog cut up in it just like his mom used to make. This is in accordance with Sheldon's statements, "Will you cut up hot dogs into little chunks and mix them in with the sauce? ...Oh! You’re in for what my mother calls a real I-talian treat," in The Spaghetti Catalyst. The hot dogs are likely a substitute for the pork neckbones cooked in traditional Italian spaghetti sauce.
 * In this episode the story is balanced between the three couples who all experience significant events in their relationships.
