Stuart: Hey, Leonard.
Leonard: Stuart.
Stuart: Uh, is this not a dress-up party?
Leonard: No.
Stuart: Was it ever a dress-up party?
Leonard: No.
Stuart: Howard, didn't you tell me it was a dress-up party?
Howard: Yeah.

Penny: Yeah, come on, Raj.
Raj: Wait, did Amy make her spinach dip?
Sheldon: She did.
Howard: And I'm gonna eat it all!

Howard: I'm not sure if I'm hoping for a boy or a girl. I mean, if it's a boy, I'm gonna have to teach him to play catch. Which means I'm gonna have to Google how to play catch.

Raj: Man, I'm worn out.
Howard: I know. Imagine if we were actually moving.
Raj: No, it's just, ever since I started dating Claire and Emily at the same time, it's exhausting.
Howard: You're exhausted? Try folding every five pages in a pregnancy book so your wife thinks you've read it.

Bernadette: (Hearing their baby's heartbeat) Wait, that's it.
Raj: Wow.
Bernadette: Isn't that the best?
Raj: You guys made a person.
Howard: We did.
Raj: And I like to think I helped.
Howard: You didn't.

Raj: Well, if that's the case, is there anything I can do to help?
Howard: Well, not right now. But we could try out that microphone you got us, and listen to the baby's heartbeat.
Raj: Really? It's okay if I listen with you?
Bernadette: Of course.
Raj: Can I squirt the ultrasound jelly on your stomach?
Howard: Hey, look at that. It's weird again.

Bernadette: He's just trying to be supportive.
Howard: Just supportive. Not over-the-top in any way?
Bernadette: No.
Raj: Hello. (Raj walks in with a gigantic teddy bear)
Bernadette: You saw him carrying that?
Howard: Astronauts saw him carrying that.

Howard: Hey, where you been?
Bernadette: Uh, Raj took me to the baby doctor and then we swung by the grocery store.
Howard: Did you get graham crackers? I mean, are - uh, is the baby okay?

Howard: I didn't know you needed help running errands today.
Bernadette: I didn't, but Raj volunteered.
Howard: Really?
Bernadette: Yeah, ever since you told him I was pregnant, he's really been making a fuss over me.
Howard: Oh. Well, I guess that's kind of sweet.
Raj: Bernie, I just forwarded you a list of the top five lactation consultants in Los Angeles. I know my favourite, but I'd love to hear what you think.
Howard: And it just got weird.

Howard: What the hell are you watching?
Bernadette: Raj found all these childbirth videos online. This one is of a woman giving birth in a river.
Howard: Okay, that is the least Jewish thing I've ever seen in my life.

Cinema Worker: Hey, guys, thank you for being a part of our test screening. You're about to be one of the first audiences to see Suicide Squad.
Leonard: Hey, you were right.
Howard: Well, I keep telling you, good things happen to bad people.

Leonard: What are we gonna tell the girls?
Howard: It's not a problem.
Leonard: I mean without lying.
Howard: And now you've made it a problem.

Howard: I don't know if we have enough solder to finish these circuit boards.
Leonard: We had a full spool yesterday.
Howard: What can I say, I play hard, I solder even harder.

Howard: "Article three: As it pertains to this project, Dr. Sheldon Cooper promises to abstain from all insulting or disrespectful language directed toward Howard Wolowitz, including but not limited to: mockery of engineering, his height, his hair, his wardrobe, and his insane belief that the Ghost Rider movie was, quote, 'not that bad'."

Howard: What are you doing?
Bernadette: I just want to make sure you've thought this through.
Howard: What's to think about? We have an invention and want to move forward.
Bernadette: Howie, you're about to form a legal partnership with Sheldon Cooper.
Howard: All right, if you're gonna calmly make excellent points, then I don't know if I want to talk to you.
