Leonard: Do you guys have a location yet? 'Cause you don't have a lot of time.
Amy: Hey, it took us nine months to pick a date, and a week to decide if brains can have lips on them, so get in the boat and row.

Sheldon: You know, I'm really happy with our wedding date. The month squared equals the square of the sum of the members of the set of prime factors of the day. Isn't that romantic?
Amy: Yes, it's like that Shakespeare sonnet, "Shall I compare thee to a day that's also a really weird math problem."

Howard: Honestly, it's gonna be hard when we both go back to work. I've been thinking maybe it would be better if one of us decided to stay home.
Raj: I don't know, I was raised by servants, and look at me.
Howard: I literally can't tell if you think that's good or bad.

Leonard: Uh, so, look, I'm here to ask you to give Sheldon and Amy the Athenaeum for their wedding.
Barry Kripke: (laughs) Why would I do that?
Leonard: Because deep down, Barry, you're a really good guy.
Barry Kripke: But am I?

Amy: What happened?
Leonard: Well, we scrubbed out some barrels of irradiated grease, rinsed off in a safety shower and then told Barry Kripke what is what.
Amy: And he just gave in?
Sheldon: Well, we agreed to invite him to the wedding.
Amy: Okay. No problem.
Leonard: And he gets to bring a date.
Amy: Well, that's reasonable.
Sheldon: A-And if she charges by the hour, we have to cover it.
Amy: What else did you agree to?
Leonard: Well, um, you know how Barry has the voice of an angel?
Amy: He is not singing at our wedding.
Sheldon: (stammers) He only wants to sing "Volare."
Leonard: Oh, "Volare". That's what he was saying. Boy, I didn't, I did not get that.

Sheldon: I said some pretty unprofessional things about his work. I may have even used the "S" word.
Amy: Subpar?
Sheldon: I'm not proud of it, Amy, but I have a temper.

Sheldon: Well, I suppose we could pick a different date.
Amy: Well, it took you nine months to choose that one. I'll pick a different husband first.

Amy: Well, we only have two months to find a venue, and I had a thought. What about the Athenaeum club at Caltech?
Sheldon: Albert Einstein was a member there.
Amy: It's beautiful.
Sheldon: Yeah, and Albert Einstein was a member there.
Amy: It's close.
Sheldon: And Albert Einstein was a member there.
Amy: And Albert Einstein was a member there.
Sheldon: Ah. Now you sound like a woman who wants to get married.

Amy: That's not much of an apology.
Sheldon: Yeah, because he's not really sorry. Obviously, he wanted a place to go where I wouldn't be and apparently all of outside wasn't enough for him.

Sheldon: Why did you lie to me?
Leonard: I don't know. It just seemed funny at first and then the longer it went on, funnier it got.

Raj: I mean he only drinks milk. Like, where are the colors coming from?

Raj: Boy, seeing them all together like that has got my biological clock ticking like crazy.
Penny: Yeah, I don't think men have-
Raj: I do.

Penny: What is this picture?
Amy: Oh, it's an MRI of our brains photoshopped to look like they're kissing.
Sheldon: Is it too sexy?
Penny: It's too something.

Bernadette: I just love them so much.
Howard: Me, too. My heart feels like it's gonna explode. Of course, it's full of brisket, so it probably will.

Howard: Oh, I didn't even know I was capable of loving someone so much.
Bernadette: More than me?
Howard: Wha--
Bernadette: Uh, I'm just messing with you. I totally love them more than you.
Howard: I get that. I would take a bullet for them. But I would get seriously mutilated for you.
Bernadette: That's sweet. But you should know, if you got seriously mutilated, I might dump you.
Howard: You'd be crazy not to. Even unmutilated, I'm no prize.
