While Raj assists Stuart with the annual Halloween party at the comic book store, Amy and Sheldon are at odds over their couples Halloween costumes.

TBBT 6x5 The Holographic Excitation Howard and Stuart

Howard gives Stuart a photo in his spacesuit.

Howard presents Stuart with his official NASA portrait (autographed, of course), [though Sheldon mentioned that he also gave one to the dry cleaners and Walgreen's drug store]. Leonard and Sheldon hypothesize that Howard will connect his trip into outer space with any subject, and decide to test their theory. Leonard succeeds immediately talking about dinner options; Sheldon initially appears to have failed, when he brings up lemons, but Howard meets their expectations moments later. Stuart decides to organize a Halloween party at his comic book store, so Raj decides to become the party planner.

Choosing the right couple's costume.

Amy and Bernadette are attending ladies' night at the Cheesecake Factory bar while Penny serves them. Amy claims that life doesn't get any better than right now, to which Penny says to herself that she hopes it does gets better. Leonard texts Penny about going out costume shopping. Penny confides in the girls that she's going to the comic book store Halloween party even though the guys that hang around there can be creepy.

Girls' night at the Cheesecake Factory bar.

Amy and Bernadette then asks, like their better halves? Bernadette also says that Leonard does things that he doesn't like to make her happy and that maybe she should take more interest in [[theoretical physics]|his work]]. Penny says that that is true, but she doesn't understand what he does, and their explanations about experimental physics don’t help, either.

Later, Amy and Sheldon are discussing their Halloween costume ideas and Sheldon surprises Amy by agreeing to go in a couple’s costume because that is one of the great advantages of being in a relationship. Amy wants to go as something like Romeo and Juliet; however, Sheldon's ideas for great costumes are R2-D2 and C-3PO or Hewlett and Packard. Amy is unmoved by his choices, and states that they should at least compromise.

Penny visits Leonard's Lab and he shows her some of his "high techy techy" equipment, including a system that scans objects and generates rotating holograms. First there is a floating pencil, which changes into a rotating Earth and then a {{w|solar system|| following by a galaxy. Leonard muses about some scientists who think that the whole universe is one large hologram. Penny remarks that she forgets how smart he really is, gets turned on, locks the door, and they start to fool around on the lab table after they take their jackets off.

Tonight you're a smurf!

In the cafeteria, Raj is discussing his Halloween–themed party foods and Howard keeps talking about his time in space. Leonard wanders in with his hair messed up and a smileon his face. Asked about what is going on and he replies "nothing." Howard says that he knows where there is a lot of nothing is and the three of the guys simultaneously answer "space".

Howard and Bernadette have just crawled into bed and things are starting to get romantic, but after six space metaphors, Bernadette stops to talk. She tells him that people are getting tired of hearing about it. Howard complains that he can't talk about the greatest adventure of his life, and she suggests that he wait until they bring it up.

TBBT 6x5 The Holographic Excitation Penny and Leonard

Penny visits Leonard's lab.

Penny is again visiting Leonard's lab as he demonstrates a floating iron ball levitated by a large magnetic force. Penny thinks it's very neat until Leonard mentions that sometimes he feels like Magneto from the X-Men. Penny replies now it seems less neat, until Leonard mentions he's wearing the black underwear she bought him. "There ya go," she replies, and starts to kiss him again. In the cafeteria, Raj is getting a Doctor Who TARDIS police photo booth for the party which excites Sheldon, while Howard is being very quiet and noncommittal. He finds that Sheldon and Raj agree that he was talking too much about space. Leonard enters again, all messed up and very happy.

Amy and Sheldon, on Amy's proviso that the both of them should compromise, are still discussing their costumes. Sheldon suggests salt and pepper, but Amy has had a bad experience with both (one of her cousins having been killed in a pepper grinding plant accident and salt making her retain water). She claims that there are three things that say that she doesn't have a made-up boyfriend: couples costumes, hickies, and sex tapes. She asks Sheldon to pick one, to which he asks what a hickey is.

At Howard and Bernadette's Apartment, they are both dressed up as Smurfs. Howard isn't that excited to go since all his friends think he is boring. Bernadette asks if he is feeling blue, laughing that that's like the funniest thing she ever said. She then pushes him out the door since she just spent three hours painting herself blue and doesn't want people to think she is a very short alien from Avatar.


Raggedy Ann and Raggedy C3PO.

At the Halloween party, Penny dresses as a sexy cop and Leonard goes as Albert Einstein. Bernadette mistakes her for a slutty cop, but Penny explains that that costume only came with a skirt and two badges. Leonard says (in a German accent) that later she was going to arrest him for traveling faster than the speed of light. Penny reminds him about their no-accent rule, to which he replies, "Sorry, officer." Stuart as Willy Wonka tries to pick up a girl, claiming to have come up with all the party food and decorations, much to Raj's disgust. Raj is Indian Jones, the love child of Indiana Jones. Amy and Sheldon show up as "Raggedy C-3PO" and Raggedy Ann due to "a compromise". Howard gets upset about not being about to talk about his space adventures because, otherwise, he is just plain old Howard Wolowitz. Bernadette reminds him that he is the best guy she knows and that she married him "on purpose." Penny and Leonard stumble out of the TARDIS all disheveled and Penny explains that there is nothing to see, only sexy police business.

Astronaut Buzz Aldrin handing out Halloween candy.

Leonard says that he was explaining to her the theory of relativity ...twice.

At the end, Howard gets a YouTube clip from Raj showing Buzz Aldrin, the second man on the moon, handing out Halloween candy to kids mentioning his trip to space to every kid. Howard tells Bernadette that he now understands everybody's objections to his boasting.



  • The TV Critic: "This was a real glass half-empty or glass half-full kind of episode. You could reasonably tell me that it was half an hour of entertainment that satisfied you or that each story was disappointing. I liked that we got four separate stories built around Halloween and an attempt to tell us something about each couple through them... While not a classic episode this was pretty entertaining. There were a lot of small gags that landed and Leonard and Penny finally had an authentic moment as a couple. I’ll take it."[2]

Costume Notes



Penny: (reading a text) Ugh, it's from Leonard. He wants to go costume shopping later.
Amy: I thought you liked Halloween.
Penny: I do. It's just that he wants to go to that party at the comic book store. A lot of the guys that hang out there are kinda creepy.
Bernadette: Like my husband?
Amy: And my boyfriend?

(The scene at the comic store party where the so furious Bernadette snatches the drink off Howard)
Bernadette: (she is very cross indeed) Whoa, Drinky Smurf. (she puts the drink back onto the table with fury. Raj looks puzzled) Can I talk to you for a second? (she now pulls Howard's arm angrily)
Howard: Great, now I’m in trouble. You happy?
Bernadette: (she sends the couple out angrily) You, out! (she's now a billion times angry) You are being very rude.
Howard: No, I’m not. They’re all being rude. And you’re being rude.
Bernadette: Me? What did I do?
Howard: (he's imitating Bernadette) Oh, Howie, stop talking about space so much. Nobody likes it.
Bernadette: (she's pouting in low voice) I don't sound like that.
Howard: You’re my wife. You’re supposed to be on my side.
Bernadette: I’m always on your side.
Howard: Then why are you trying to take this away from me? Being an astronaut is the coolest thing I’m ever gonna do. If I stop talking about it, then I’m just…
Bernadette: Just what?
Howard: Just plain old Howard Wolowitz again.
Bernadette: Plain old Howard Wolowitz is the best guy I know.
Howard: You’re just saying that.
Bernadette: No, I’m not. I married him. On purpose. Come here.
Howard: I love you.
Bernadette: I love you, too.

Sheldon: It’s fascinating. Let me see if I can duplicate the result. Howard, I’ve always thought the lemon was an underrated fruit. Care to weigh in?
Howard: Not really.
Sheldon: Oh, well.
Howard: You know, people say the Soyuz capsule was a lemon. But, hey, that baby got me to space and back.

Howard: Boy, it’s nice to sleep in a bed with gravity again. (Bernadette takes her glasses off and puts on the bedside table) Did I tell you about the night my retainer floated out of my mouth and into the air lock?
Bernadette: (she's so tired of Howard's space story) Yeah, you mentioned it once or twice.
Howard: So, here we are, just a couple of young newlyweds. What to do? What to do to you? Astronaut Wolowitz, reporting for booty. Preparing thrusters. We have liftoff. Are we clear to jettison that nightgown?
Bernadette: (she's encourging Howard crossly) Okay, we need to talk.
Howard: What?
Bernadette: (1st time: she speaks in soft firmness) Howie, I know you went to space. I’m incredibly proud of you. But you might want to try and not bring it up every minute.
Howard: I don’t talk about it every minute.
Bernadette: (2nd time: she speaks in soft firmness) Tonight at dinner you went on bout it for an hour straight.
Howard: What was I supposed to talk about? We were eating at Johnny Rockets.
Bernadette: (3rd time: she speaks in soft firmness) I’m just saying, people are getting a little tired of it.
Howard: So, I did this amazing thing and I’m never allowed to mention it?
Bernadette: Of course you can. But maybe a good rule would be to wait for people to bring it up.
Howard: Okay, no problem. It won’t happen again.
Bernadette: I love you.
Howard: I love you, too. I can’t tell you how many times I dreamed I was in bed here with you when I was… you know. What, I can’t even point?
(Bernadette now gives Howard a hard glare just as the scene fades to black)

Bernadette: Thanks, so do you. Slutty cop?
Penny: No, sexy cop. Slutty cop only came with a skirt and two badges.
Bernadette: And Albert Einstein?
Leonard: Ja, und later she’s going to arrest me for goink fashter zen da shpeed of light.
Penny: I thought we said in the car, no accents?
Leonard: Sorry, Officer.

(Howard is dressed as Papa Smurf, reading a magazine. Bernadette walks in the room dressed as Smurfette.)
Bernadette: How do I look?
Howard: Fine.
Bernadette: Uh-oh, is someone a little blue? Come on, Howie, that’s like the funniest thing I’ve ever said in my life. What do you say? You ready to go?
Howard: To tell you the truth, I’m not really in the mood.
Bernadette: What are you talking about? It’ll be fun. All your friends’ll be there.
Howard: Yeah, some friends. They all think I’m boring. Maybe you should go without me.
Bernadette: No, if I’m there alone, people might think I’m just a really short person from Avatar.
Howard: I’m sorry. I just don’t want to go.
Bernadette: (she is now very cross) Hey, I just spent the last three hours coloring myself blue. I’m gonna be washing paint out of my Smurf for a month.
Howard: Fine. Two weeks ago I was an astronaut.
Bernadette: (she is still very cross) Yeah, well, now you’re a Smurf. Keep walking.
