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: You know, I'm really glad you decided to learn Mandarin.
Sheldon: Why?
Howard: Once you're fluent, you'll have a billion more people to annoy instead of me.

Josh: So, I have to ask, was the robot sexy?
Howard: It was actually just a mechanical hand.
Josh: 'Cause that's all you need, right?
Howard: You are my brother.

Sheldon: Sheldon Cooper does not cry.
Howard: That's true, you'd rust.

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.

Penny: I'll see if it's available.
Amy: You know, if that study's real, Leonard might come back smarter than you.
Sheldon: Are you trying to manipulate me?
Amy: Yes.
Sheldon: Well done, it worked, we're going.
Amy: Yay!

Raj: Of course. I'll give you guys some space. Let me just get this out of your way. (Raj fumbles around trying to move the gigantic teddy bear. He knocks over various objects in Howard & Bernadette's living room)
Howard: You need some help?
Raj: No, I got it.
Bernadette: Raj, Raj, wait.
Raj: Please, Bernadette. Let me leave with my dignity. (Raj falls over the teddy bear as he tries to move it out the door)
