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.

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.

Bernadette: Maybe we should get one of those machines to help her up the stairs.
Howard: You mean a forklift?

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)
