Sheldon: Well, I would say that this constitutes a catering crisis.
Amy: I agree. Who's gonna step up and handle it?
Leonard: Doesn't matter. This is fine.
Amy: Penny?
Penny: (mouth full) What?
Howard: You know what? I'll take care of it.

Sheldon: Excuse me, b-before we start eating, I-I would like to make a toast.
Leonard: Oh, nice.
Sheldon: If only I could think of one. Someone else go.

Penny: Hey. Here's the sewing kit you asked for.
Sheldon: Ooh! A minute, 19. Quick.
Penny: You were timing me?
Sheldon: Yes. I am going through a bit of a timing phase. How long will it last? We'll find out.

Sheldon: Maybe we're being old-fashioned, defining these roles by gender. You know, historically, the best man's role was to defend the bride and groom in combat. I mean, if that's not Penny, I don't know what we're doing here.

Bernadette: It's really sweet of you to come by and keep me company.
Sheldon: Agreed.

Sheldon: So, listen, I have a secret that I need to tell someone. But you can never say a word. Not even to Howard.
Bernadette: I'm your girl. Lay it on me.
Sheldon: Really? You keep things from your husband?
Bernadette: No, I tell him everything. Don't be a child.

Sheldon: Okay. Here it is. I can control the thermostat in Leonard's apartment with my phone. And when he makes me mad, I turn it up, slightly.

Howard: Oh, hey. I didn't know you were here. What are you two talking about?
Bernadette: Literally, nothing interesting.
Sheldon: [whispering] Oh, you're good.

Leonard: Did Sheldon and Amy give you guys that puzzle, too?
Howard: Yeah. Is it just me or have they been acting strange?
Leonard: I don't think they're acting.

Sheldon: Just out of curiosity, which one of you figured it out?
Howard: I did.
Sheldon: Impressive. [rubs out Howard's score on the leaderboard]

Howard: So, bottom line, what you did was wrong and cruel, which the mother of my children finds oddly appealing.
Amy: So she still wants to be my maid of honor?
Howard: Maid of honor, hit woman, whatever you need. Make the call.

Amy: What if we have a code word?
Sheldon: Ooh, now you're speaking my catamaran. That's my code word for "language."
Amy: Okay, fine, catamaran. That's our code word.
Sheldon: No, that's my code word. Get your own.

Penny: So Leonard, tell everyone your news.
Leonard: Oh, oh, I'm starting a book.
Sheldon: That would be big news from Penny, but you've read a book before.

Leonard: Yeah, did Sheldon send it to you?
Penny: Amy did. I solved it already.
Leonard: Really?
Penny: Yeah. Same way I solved my jury duty summons, I threw it away.

Sheldon: You know, I don't know how I feel about all this baby-proofing. If Halley can't teach herself to walk down the stairs, then maybe that's nature's way of saying the Wolowitz line ends here.
