Howard: Hey, we're here to support you, buddy.
Leonard: No, you're not. You're here to see if I get my underwear pulled over my head.
Howard: You wore underwear? You fool.

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.

Leonard: Do you think we can outrun him?
Sheldon: I don't need to outrun him, I just need to outrun you.

Penny: Did Sheldon change the Wi-Fi password again?
Leonard: Yeah, it's "Penny already eats our food she can pay for Wi-Fi". No spaces.

Sheldon: I'm not going to say I told you so, but we could have killed him.
