Raj: What is there to get? She doesn't want to fall in love. At that point, all we are is two single people who find each other attractive and enjoy having-- Oh, got to go!

Penny: Hold on. Where is he?
Leonard: Well, according to his text, he was on the second floor, then he stopped to tie his shoe. (phone chimes) All tied, and-
Sheldon: Hello!
Amy: Hi.
Sheldon: Sorry we're late. Amy took forever tying my shoe.

Raj: Everything okay?
Bernadette: Yeah, there's just something I need to ask you.
Raj: (gasps) Oh, Bernie, I'd be thrilled.
Bernadette: It's not be my birth coach.
Raj: Okay, that hurts, but luckily I know how to breathe through it.

Bernadette: I know I sound paranoid, but I'm feeling really vulnerable. If there's anything you could find out, it'd be great.
Raj: And if she is up to anything, what are you gonna do?
Bernadette: Nothing. I'll just calmly talk to her and explain there are certain boundaries that need to be respected. It's really for the benefit of everyone at the company.
Raj: Uh, okay, what you're saying sounds nice, but the way you're saying it is causing my testicles to take cover in my abdomen.

Leonard: You know what, you like to think that you're just like Tesla, but the truth is you're exactly like Edison.
Sheldon: You take that back!
Howard: No, he's right. You are a bully, a credit hog and a self-promoter. And if anyone around here is like Tesla, it's us.
Leonard: (long pause) Yeah.

Amy: Well, you are building on their work and taking the credit for it. That's a classic Edison move.
Sheldon: Oh, yeah? Well, if I'm Edison and you love me, then what does that say about you?
Amy: I honestly don't know.
Sheldon: Okay. Well, I have to Google some stuff about Mrs. Edison. I'll be right back.

Bernadette: I never would've undermined a coworker.
Raj: What? Oh, please. Wh-What about that guy Eric, who you told it was "Bring Your Cat to Work Day" when you knew your boss had asthma?
Bernadette: That was just a hilarious prank that ended with me getting a corner office.

Howard: So what do you think? Can you make it work?
Barry Kripke: Uh, I just need to use the cross section to calculate the probability of the interaction.
Leonard: Can we help?
Barry Kripke: Yes. Why don't you run get me a can of Pringles.

Sheldon: Leonard, I was- What's Kripke doing here?
Leonard: Oh, he's just helping us develop a better, more efficient neutrino comm system that we're gonna pitch to the military, making yours obsolete.
Howard: Yeah, Leonard thought of it. It's genius.
Leonard: Oh, thanks. You see, instead of using liquid helium-
Howard: Good God, man, shut up!

Raj: I can't believe she dumped me.
Bernadette: This is tough for me, 'cause I can.

Leonard: Based on Kripke's calculations, I think this is gonna work. Maybe we should pitch it to Colonel Williams today.
Howard: Why limit ourselves to the U.S. military? I bet there's a lot of other places we could take this.
Leonard: Without committing criminal espionage?
Howard: You know, it's easy to shoot an idea down, Leonard.

Leonard: She's right. Maybe we're all a bunch of Teslas after all.
Amy: Didn't Tesla die penniless, forgotten and insane?
Howard: (sighs) You may have a point about her social skills.

Stuart: I'm, uh, I'm running a special today, uh, buy something, keep having a comic book store to come to.

Raj: Why are they making four more Avatar movies? It's not like the first one is even that good.
Leonard: What are you talking about? You love that movie. You even went as Avatar for Halloween.
Howard: I remember. That was not a lot of clothes.

Leonard: I can't believe we forgot about it.
Howard: It's not that surprising. They were basically worthless when we got them.
Leonard: I wish I knew how much we had.
Raj: Sheldon, you must remember.
Sheldon: Of course I do.
Stuart: Oh, yeah, he and I totally remember. You tell them, Sheldon.
