Bernadette: Who's Trent?
Howard: Oh, he's our fan.
Bernadette: Fan of what?
Howard: Uh, did you forget? We're in a band.
Bernadette: You mean because you played one time in the comic book store?
Howard: And at the children's hospital until they asked us to leave.

Raj: Good for Sheldon, deciding to stay with Amy on her birthday.
Leonard: I know. It's still gonna be weird to see the movie without him.
Howard: We could wait a couple of days and see it together.
*All three laughing*

Howard: Here we are talking about Frozen, and yet, you got burned.

Howard: I'm gonna check the temp on the tub.
Bernadette: Don't make it too hot.
Howard: Sorry, but "too hot" is the only temperature I come in.
Bernadette: Look at that. You shaved it all.
Howard: You're welcome.

Bernadette: It's not moving, but I think it's still alive.
Howard: Well, should we put it back in there a few minutes?

Howard: Should we name him?
Bernadette: It is Valentine's Day. How about Valentino?
Howard: Nice. A classic rabbit name. Peter Rabbit, Roger Rabbit. Valentino Wolowitz Rabbit.
Oh, look at all that chest hair and overbite. Of course you're a Wolowitz.

Leonard: Buddy, I think you might be overreacting.
Howard: And then there's this nose. I mean, what if he looks like me? Or worse what if she looks like me?

Howard: Oh, my God, and do you have any idea how expensive having a kid is?
Raj: I read that in Los Angeles, raising a child through college can cost over a million dollars.
Howard: A million dollars? God, it's like my nuts just kicked me in the nuts.

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.

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.

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.

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.

Bernadette: You all right?
Howard: I'm fine. Just a little embarrassed I had to be carried down the stairs like a baby. (To Penny) Thanks.

Zack: So how's the science world? What are you guys up to?
Howard: We've actually been working on a prototype for a navigation system we invented.
Leonard: But we won't bore you with the details.
Zack: Are you kidding? I love science. Einstein, Stephen Hawking, Mike deGrasse Tyson.
Amy: Mike deGrasse Tyson?
Howard: Yeah, you know, the boxer who grew a mustache and became a scientist.
