Leonard: Uh, also no talk of Rocky IV.
Bernadette: Why Rocky IV?
Howard: Because he fights a Russian. I'm sorry about her.

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.

Howard: I invented a game. Want to play?
Leonard: Sure.
Howard: It's called Emily or Cinnamon. I give you actual quotes I've heard Raj say, and you guess if he was talking to his girlfriend or his dog.

Bernadette: Does your mother call you every day at work to see if you had a healthy lunch?
Howard: My mother calls me every day at work to see if I had a healthy bowel movement.

Sheldon: Thanks, Dad. We're gonna give them hell.

Leonard: I have something that might help. It's-it's a recording of the only person whose opinion Sheldon actually respects.
Amy: Hawking? Feynman?
Leonard: No, himself.

Amy: Hey.
Sheldon: Hello.
Amy: "Fine with flags"?
Sheldon: Yes, flags, up there flapping around on poles. If you think about it, they're just the strippers of the emblem world.
