Raj: (Inside the closet) Don't forgive them. Stay mad at them.
Howard: What is he doing in there?
Raj: Busting you.
Bernadette: It's okay. They apologized.
Penny: Yeah, it's fine.
Raj: Well this is kind of anti-climactic.
Howard: You know what wasn't anti-climactic? The end of the movie. Get this.
Raj: No spoilers. No spoilers.
Penny: And he's back in the closet.

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.

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.

Howard: You want to come with us?
Bernadette: I'm kind of getting into the groove here.
Penny: Yeah, you guys run to the store and let the women handle the science for a change.
Leonard: Okay. We'll be back as soon as we can.
Penny: (To Bernadette) Okay, so what is solder?

Penny: Hey, guys.
Leonard: Hey. What are you doing here?
Bernadette: We heard there were some sexy scientists working hard all weekend.
Penny: Yup, so we brought you some lunch and we are gonna go look for 'em.

Penny: So, hows it goin'?
Leonard: Good. Slow.
Howard: There's a lot of tedious setup, but once we get through that it should go quicker.
Penny: Is there anything we can do to help?
Leonard: You know what, this part isn't that technical. You actually could.
Penny: Wow, really? Called my bluff. All righty then.

Bernadette: Can we really help?
Howard: While we finish soldering these boards, it'd be great if you guys could wrap these pipe fittings with Teflon tape.
Leonard: I'll show you how to do one.
Penny: Hey, wouldn't it be funny if after all your years of hard work, I'm the one who makes a scientific breakthrough? (To Bernadette) He doesn't think that's funny.

Leonard: They've been out there a while.
Amy: I hope everything's okay.
Sheldon: I wonder what they're talking about.
Penny: (eavesdropping at the door) If you guys would shut up, I could tell you.

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!

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: 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.

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.

Sheldon: Thank you. That was wonderful.
Penny: Oh, wait, wait, wait. Stuart didn't get to speak.
Stuart: Oh, oh, okay. Um. Uh, Sheldon, I've spent most of my life feeling invisible, but having you and everyone-
Amy: Hey, everybody, listen up.
Penny: (To Stuart) You nailed it.
