Howard: How do I know what you said? Damn you and your noise-cancelling breasts.

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: Raj, your tag's sticking out. *Bernadette tucks Raj's clothing tag back in*
Raj: Thank you. That's the closest I've come to sex in like two years.
Bernadette: Now I feel a little gross.
Raj: You're only making it seem more real for me.

Sheldon: I have one question. Is this a prank? Where you land in Houston and you've made up wanted posters which have my face with a moustache and a Spanish name, and I get arrested and deported to South America?
Howard: No.
Sheldon: Well I'm glad, because I would not have seen that coming.

Howard: Listen, I was thinking you and I could probably try to be better friends.
Sheldon: Really? I was thinking what we have now is a bit much.
