Stuart: Hey. Hey, look at you guys!
Amy: I'm Raggedy Ann, and he's Raggedy C-3PO.
Sheldon: It was a compromise. I lost.

Howard: A week ago, I was an astronaut.
Bernadette: Yeah, well, today you're a Smurf! Keep moving!

Howard: Okay, here it is. Bernadette said you guys are all sick of me talking about my trip to space. Is that true?
Sheldon: Yes.
Raj: No.
Sheldon: We seem to have different approaches here. I was going for helpful honesty. I have no idea what you're doing.
Raj: It's called being nice.
Sheldon: Okay. If you think being nice will get him to shut up, I'll try it.

Raj: Would you like me to help? I do have a certain je ne sais quoi when it comes to soirees.
Stuart: Thanks, but I can't afford je ne sais quoi. How much for just quoi?

Howard: (Mimicking Bernadette in a high voice) Oh Howie, stop talking about space so much. Nobody likes it.
Bernadette: (In a low voice) I don't sound like that.

Bernadette: Leonard does things he doesn't like to make you happy.
Penny: Well, yeah he's my boyfriend, isn't that like his job?
Amy: Then what's your job?
Penny: Letting him make me happy.

Sheldon: What if we were to go as dinner table favourites salt and pepper?
Amy: You know salt makes me retain water and my cousin William was ground to death in a pepper factory accident.

Bernadette: Whoa, Drinky Smurf.

Amy: There are certain things that say to the world, I have a boyfriend and he's not made up. Matching cotumes, hickeys and sex tapes. Pick one.
Sheldon: What's a hickey?

Penny: What's-what's that?
Leonard: Uh, that is an integrated ion trap and time-of-flight mass spectrometer.
Penny: Wow. High-techie-techie. What's this little box?
Leonard: That is a pencil sharpener.
Penny: Ooh, low-techie-techie.

Stuart: "To Stuart, your comic book store is out of this world. Just like the guy in this picture was."
Sheldon: For the record, he also thinks Walgreens and the dry cleaners are out of this world.
Howard: That's not true. At Walgreens I was over the moon for their store-brand antacids.

Bernadette: I just think in relationships you get back what you put into them.
Amy: That's not always true. Last night, I gave Sheldon my best come-hither look, and he responded by explaining how wheat came to be cultivated.

Amy: I think I'm gonna try green tea mixed with lemon zinger.
Sheldon: Two tea bags in one cup? You're not at a rave.

Sheldon: Couples costumes are one of the few benefits of being in a relationship. Now imagine this, you and I entering Stuart's party and all eyes turn to see America's most beloved and glamorous couple.
Amy: Yeah?
Sheldon: R2-D2 and C-3PO. Dibs on 3PO.

Sheldon: How about one of the most beguiling and influential couples of the 20th century? Hewlett and Packard. Dibs on Hewlett.
What? You want to be Hewlett?
