Penny: We should just try and avoid anything that makes them think of their project or science or Nobel Prizes or successes or failures.
Amy: Hi.
Leonard: Hi!
Penny: Hey, guys.
Raj: Hey!
Amy: What are you guys doing?
Bernadette: Nothing.
Sheldon: Nothing? Like what my career has come to? Thanks a lot.
Howard: Nice going.

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.

Leonard: It's a pep talk he made when he was a kid. He gave it to me years ago and told me to save it for a real emergency.
Penny: What? You didn't break it out when he declared his room a sovereign nation and waged a trade war against us?
Leonard: His major export is talking. I didn't want that anyway.
