Leonard: Isn't Halley's birthday the same as Amy's?
Howard: Yeah, but we're not doing anything big 'cause she's one, Bernadette's on bed rest, and (clears throat) I'm lazy.

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: Can I get you anything else?
Amy: No, thanks. I think I'm good.
Sheldon: You sure? There's still plenty of pork fat. Although, if we don't eat it, I suppose we could turn it into soap.
Amy: That might taste better.

Sheldon: Uh-oh.
Amy: What?
Sheldon: I left the food out.
Amy: You afraid it's gonna go good?

Sheldon: So this is for Amy's birthday. Can I leave it here?
Leonard: Sure. What is it?
Sheldon: A butter churn.
Penny: Aw, that's what I got her.
