Howard: Raj is a proud, passionate man. If you go running out on him again, you're only gonna get like three of four more chances before you are history.

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: She's remarkable.
Leonard: She really is.
Sheldon: How is it that she can remember all those lines, yet as a waitress she can't remember no tomato on my hamburger?

Bernadette: It smells pretty ripe in here. You kinda feel it in your eyes.

Lucy: I'm kind of broken.
Raj: That's great. I'm broken, too.
Lucy: Oh, no you're not.
Raj: Oh, I totally am. If it wasn't for this beer, I couldn't even talk to you right now. I'm a wreck. There are many things seriously wrong with me. And not quirks, either. Like diagnosable psychological problems. Maybe brain damage.
Lucy: Well how do I know you're not just saying that?
Raj: Go out with me on one date. I promise you, you'll see.
