Leonard: Okay, I'd better go in there and talk to him.
Amy: Well, don't you think I'm the one who should go in?
Leonard: No offense, but I've known the guy a really long time.
Amy: Well, I've, you know, seen him without pants on.
Leonard: Again, no offense, but so have I.
Amy: Well, he's seen me without pants on.
Leonard: Again, -
Penny: Okay, this is ridiculous.

Amy: So, have you been having any morning sickness?
Bernadette: A little. And it doesn't help that I've got this heightened sense of smell.
Penny: Is that a pregnancy thing?
Bernadette: Yeah, the other day I sniffed out where Howie hid the Girl Scout cookies. No more Tagalongs, my ass.
Penny: But now you'll be able to make your own milk to eat the cookies with.

Penny: Come on, just open it.
Raj: You know, on Game of Thrones, Balon Greyjoy received his son's genitals in a box.
Penny: Well, never hurts to have a spare.

Bernadette: What is that?
Raj: Wow, it's an antique sextant. Sailors used these to find their position by the stars.
Amy: What a nice gift for an astrophysicist.
Raj: I know, she's so thoughtful.
Penny: See, she's trying to get you back. Now, that is exactly what I would've gotten you if I had any idea what it is or what you do.

Bernadette: I wonder how much she spent on this.
Amy: Ooh, let's find out.
Raj: It doesn't matter. It's the thought that counts.
Penny: Yeah, yeah. Beauty's on the inside, size doesn't matter - how much did she spend?

Raj: Oh, guys, it's Emily. What should I do?
Penny: Okay, answer it. Just be strong. And if she starts to cry, don't make any promises. And most importantly, put it on speaker so we can hear.

Bernadette: I'm a little tired, Howie. You ready to go?
Howard: Yeah, one sec. I just need to sign this contract.
Bernadette: What is it?
Howard: Well, we ran into a problem about my share of the patent, so we're forming a partnership to split anything we make equally.
Penny: Sheldon, did you draft the contract?
Sheldon: You bet I did.
Penny: Ooh. (To Amy) You're gonna make out so hard tonight!

Penny: How can you call yourself a scientist and run out of solder?
Leonard: Well, funny story. So, we have plenty of the 60/40 tin-to-lead ratio solder, but the spools look a lot like the 63/37 tin-to-lead.
Penny: Honey, honey, honey, let me stop you. That is, is not a funny story.

Raj: Hey. Where are the guys?
Penny: Oh, they went to the store to get solder, which is metal you melt to make science things.

Leonard: Hey.
Howard: Hi.
Penny: Hey, what's this?
Leonard: Listen, we did a stupid thing.
Howard: We went to a movie and lied about it, but we feel bad and want to make it up to you.
Leonard: So, these are for you, and if you're not too mad, we'd love to take you guys to dinner.
Howard: Yeah. Anywhere you want.
Bernadette: Oh. Well, thank you for being honest.
Penny: Yeah. You know, I want to be upset, but we did kind of have fun working on the prototype.

Penny: This place is great.
Leonard: So nice of that doctor to just let you use it.
Penny: Well, she is taking me to an Indigo Girls concert, so hold that thought.

Sheldon: Yeah, provided he has already read Infinite Crisis and 52, and is familiar with the re-establishment of the DC multiverse.
Penny: What's a multi-verse?
Sheldon: Get her out of here.

Penny: Okay, you know what? This is ridiculous. I've been trying to make a connection with you all day, and clearly I'm getting nowhere.
Beverly: Well, are you seeking a connection or just some form of validation?
Penny: What I was seeking was some sort of friendship. But at this point, I'll take you not insulting me to my face.
Beverly: My intention was never to insult you.
Penny: You've been doing it all day. Do you even know what an insult is?
Beverly: Well, it's not a clinical term. But one example would be your marrying my son, and not inviting me or even telling me the wedding was taking place.
Penny: Okay, good example.

Leonard: Penny, I've always known I loved you, but this last year has shown me that I also love being married to you. Thank you for saying yes.
Penny: Oh, thanks for asking until I did.

Sheldon: Alright, let me put it this way. Your gross receipts on this one order will be over $3,000 for one night's work.
Penny: You guys get started.
Leonard: What are you doing?
Penny: Going online to buy shoes!
