Howard: Uh, I was thinking maybe one of us should stay home full-time, with the kids.
Bernadette: Oh great, so I have to give up my job and everything I've worked for?
Howard: Actually, I was thinking I should stay home.
Bernadette: Oh, so I have to abandon my children and go back to work, while you get to stay home and bond with them?
Howard: You just said you didn't want to.
Bernadette: No, I don't want to have to, but if I want to, I should get to.
Howard: Do you want to?
Bernadette: Maybe I do.
Howard: What if I also want to?
Bernadette: Well, I don't know, we can't both stay home.
Howard: Don't you think you should go back to work, because you make more money?
Bernadette: Don't you think you should make more money?
Howard: I think it's pretty sexist of you to say a dad can't stay home with his children.
Bernadette: You know what else is sexist, the phrase "suck it", yet here we are.

Howard: I'm sorry I didn't take you to the airport. I just want you to know I'll never forgive myself for being so selfish. And I promise to keep you close for the rest of my life.
Bernadette: Oh, no, that thing's gonna end up in my bedroom.

Bernadette: (Shouting from the bathroom) How many times do I have to tell you to replace the toilet paper when it's empty?
Howard: I'm in the middle of something.
Bernadette: So am I!

Bernadette: Gosh, Amy. I'm sensing a little hostility. Is it maybe because like Sheldon's work, your sex life is also theoretical?

Leonard: Do you guys have a location yet? 'Cause you don't have a lot of time.
Amy: Hey, it took us nine months to pick a date, and a week to decide if brains can have lips on them, so get in the boat and row.

Howard: Honestly, it's gonna be hard when we both go back to work. I've been thinking maybe it would be better if one of us decided to stay home.
Raj: I don't know, I was raised by servants, and look at me.
Howard: I literally can't tell if you think that's good or bad.

Sheldon: You know, I'm really happy with our wedding date. The month squared equals the square of the sum of the members of the set of prime factors of the day. Isn't that romantic?
Amy: Yes, it's like that Shakespeare sonnet, "Shall I compare thee to a day that's also a really weird math problem."
