Bernadette: It's just furniture.
Howard: It's my mom's furniture. It belongs in the house I grew up in, next to that pile of TV Guides and in full view of what, for a ten-year-old, was a quality piece of string-art!

Penny: I don't want five dollars, I want my dignity.
Amy: So, what are we talking, like ten bucks?

Leonard: To Mrs. Wolowitz. A loving mother. To all of us. We'll miss you.

Sheldon: I've invented a science joke. Would you like to hear it?
Amy: Sure.
Sheldon: How many Edisons does it take to screw in a lightbulb?
Amy: How many?
Sheldon: Who cares? He stole the idea and doesn't deserve his own joke.

Sheldon: But that doesn't mean that you should be standing on street corners, handing out your math to whatever guy comes along.

Penny: Besides, aren't you the one who says there's nothing more important than the advancement of science?
Sheldon: No, I said there's nothing more important than me advancing science.

Customer: I think you made a mistake, I'm not an actor.
Raj: Don't say that. I mean, you're not Dame Judi Dench, but you're pretty great.

Leonard: So you guys were testing us both? What is the matter with you?
Penny: What's the matter with them is they both think they're so smart, they don't care if they hurt other people's feelings.
Amy: That's not true.
Sheldon: That sounds like us.

Penny: I really thought he was going to say "let it go".

Amy: Penny, I really want to eat this banana, but it's stuck inside this bamboo puzzle box.

Leonard: Why don't we go get the food for the party?
Stuart: Thank you.
Raj: Smart. Looks like we're being helpful.
Leonard: When really we're just exiting an uncomfortable situation. *fist bumps with Raj*

Howard: That is a good point. But I didn't marry you for good points. I married you to blindly support me no matter how ridiculous I'm being.
Bernadette: This is why I had to rewrite our wedding vows.

Leonard: If he's not nice, it's gonna make it hard for me to watch him in anything again.
Raj: The guy who plays Jon Snow was a jerk, we still watch Game of Thrones.
Leonard: He was a jerk because you rear-ended him.
Raj: I was distracted. It's weird seeing a member of the Night's Watch with a kayak strapped to his car.

Raj: Hang on. If you're really Nathan Fillion, what's the line from Firefly about your bonnet?
Customer: I swear by my pretty floral bonnet, I will end you.
Leonard: That's it. That's the line.
Raj: Although, I knew the line, doesn't make me Nathan Fillion.

Penny: What's up?
Sheldon: I'm mad at Amy.
Penny: Did you she leave pit stains in your favorite crop top, too?
