Let's have a toast. To Mrs. Wolowitz. A loving mother ... to all of us. We'll miss you.

Leonard

Sheldon: I didn't care for her yelling, but now that I'm not going to hear it again, I'm sad.
Leonard: If you want, I can yell at you later.
Sheldon: It won't be as good.

Sheldon: When I lost my father, I didn't have any friends to help me through it. You do.
Penny: I really thought he was going to say, "Let it go."

No. My mom died.

Howard

Nathan Fillion: How about a guy who looks like Nathan Fillion, but a little more annoyed than Nathan Fillion usually is?
Leonard: What do you think?
Raj: Aww. That's good enough for Facebook.

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

Oh, hey! Did you see that? I figured out how to open my door all by myself. Maybe I'll fling some feces around my cage to celebrate.

Penny

Nathan Fillion: Oh, umm. I think you made a mistake. I'm not an actor.
Raj: Don't say that. You're not Dame Judi Dench but you're pretty great.

Raj: The guy who plays Jon Snow was a jerk and 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 kayak strapped to his car.

Are you folding that like a crazy person to get me to do it?

Sheldon

Sheldon: Gee, Penny. Life's given me lemons, what should I do?
Penny: You could shove them somewhere.
Sheldon: Okay, now you're getting creative.

Sheldon: How many Edisons does it take to screw in a light bulb?
Amy: How many?
Sheldon: Who cares he stole the idea and doesn't deserve his own joke.
