Leonard: We're pinned down!
Howard: We can't get through!
Raj: Sheldon, get over here and help!
Sheldon: Okay, one second.
Leonard: Sheldon, why are you jumping up and down?
Sheldon: I'm trying to shoot.
Howard: Then use the shoot button, not the "wonderful thing about Tiggers" button!

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.

Sheldon: Physicist, baker, lover, what can't I do?

Penny: I didn't know you could drink while you were breastfeeding.
Bernadette: Yeah, they say the yeast in beer helps with milk production.
Amy: I'm pretty sure that's a myth. Let me check.
Bernadette: Ruin it for me, and I'll break this glass over your head.

Penny: You want food?
Bernadette: Yeah, breastfeeding burns, like, 5,000 calories a day. (To Amy) Do not touch that phone!
