Leonard: I'll give it a go. My ride home with you was hellish.

Penny: Okay, what is going on?
Sheldon: Well, ever since Amy started working with Howard, she hasn't been home.
Penny: Didn't that just start this morning?
Sheldon: And has she been home?

Raj: You say you're busy as bees, yet here you are, dancing. Although I suppose bees do dance, but their dance lets other bees know where the pollen is, and yours does not. So my logic, despite that slight detour, does track.

Leonard: You can't think this is the right time to "validate his behavior."
Penny: Okay, what about "presenting a united front"?
Leonard: What about you coddling him and he's never gonna learn?
Penny: Look, you sound frustrated, and I'm really proud of the way you're able to state your opinion.
Leonard: Thank you. Wait, no, no. Don't use that book on me!

Howard: Amy, your lab is amazing. A C-arm fluoroscope, a cranial ultrasound, (gasps), and look at that coffee maker!
Amy: I know. On our expense report, I listed it as "Eduardo", my Colombian lab assistant.

Sheldon: See, he gets Ewoks in his bed.
Amy: You've got Chewbacca. That's enough.

Penny: Yeah, no more stories about sex, so, Amy, that brings us to you.
Amy: Well, at work we've been doing some interesting research with neuroprosthetics.
Penny: Neat. I've been rewatching The O.C., so we're all leading productive lives.

Amy: We've been working on a computer interface that can use brain wave patterns to control robotic limbs, but we're having a little trouble localizing the signal from the EEG cap.
Howard: Oh, well, have you thought about adding a phased array of sensors for better localization?
Amy: Actually, that never occurred to me.
Penny: It never occurred to me I would miss the Ewok conversation.
Leonard: Good, because I just bought another one on Amazon.

Amy: You know, I could use an engineer on this project.
Sheldon: Well, now, this works out great. Howard's an engineer. I'm sure he knows someone qualified.

Penny: Bernadette left it here.
Leonard: Yeah? Anything interesting?
Penny: Well, I just saw a picture of a baby's head crowning, so I hope you enjoyed sex, because we're done with that.

Leonard: Hey, Sheldon, what's up?
Sheldon: Well, remember how disappointed you were when Amy started driving me to work?
Leonard: Sure, uh, sometimes people smile a big smile of disappointment.
Sheldon: Yeah, well, good news, Amy had to go in early to show Howard around her lab, so you get to drive me.
Penny: Aw, his smile of disappointment has turned into a frown of joy.

Leonard: So Howard and Amy working together, that's interesting, huh?
Sheldon: Eh, it's all right, I suppose. Uh, when- Usually when Amy complains about her coworkers, I just tune her out, but now I'll be able to join in and pound away.

Raj: I came to see how you were doing. Like, uh, do you need help with anything?
Bernadette: Oh, thank you. There are a few things around the house that I've been waiting for Howard to get to. The smoke alarms-
Raj: No, I meant emotionally. How are you feeling?
Bernadette: Like you're not really here to help me.

Bernadette: Everything's fine. Howard's really excited about his work, he's been in a great mood I'm really proud of him.
Raj: And I can fit into the pants I wore in high school. Come on, we don't need to lie to each other.
Bernadette: You're right. I have a teething baby, I'm pregnant, I have a proposal due tomorrow. I don't have time to hear about how much you're missing my husband.
Raj: Well, I think I know why he's been working so late.

Amy: Hi.
Sheldon: Welcome home. How was work?
Amy: Great. Howard had an idea for-
Sheldon: (waving his hand dismissively) That's enough about work.
