Raj: Maybe you don't want someone exactly like you. You know what they say: opposites attract.
Sheldon: Well, by that logic, I should be with someone short, dull and needy, eh? Not to cast aspersions, but I can't shake a stick around here without hitting that.

Dave: You know, I once drove 500 miles to hear him speak at Stanford.
Amy: I have a DVD of that lecture.
Dave: Really? Wasn't it great?
Amy: Not as a Valentine's present, no.

Dave: Well, the next time you watch it, I'm the bloke who asked the question that he said was stupid and obvious. It was the nicest thing he said to anyone there.
Amy: That's, um, terrific.

Penny: Oh, damn it, we should have brought binoculars.
Bernadette: Right here.
Leonard: We just happen to have those in the car?
Bernadette: Kinda. Before I met Howie, I liked to keep close tabs on my boyfriends.
Leonard: By stalking them?
Bernadette: No. Stalkers are creepy. I'm just a harmless little girl with military-grade spy equipment.

Leonard: Can I see?
Penny: What, now you're interested? You didn't even want to come.
Leonard: I know, but you guys make being a crappy friend look fun.

Leonard: It looks like they're having a nice time. I wish I could hear what they're saying.
Bernadette: Yeah, I should've brought my parabolic microphone.
Penny: Your what?
Bernadette: Nothing. Not important.

Leonard: Okay, we saw them. Can we go catch the movie?
Bernadette: Why'd you bring him?
Penny: I had to. We're married now.
Bernadette: Ugh, I hear that.

Leonard: I don't understand why we're leaving so early for the movie.
Penny: Oh, I forgot to tell you, we're gonna meet up with Bernadette to spy on Amy and her date.
Leonard: What? I don't want to do that.
Penny: What, and you think I want to see a documentary about aluminum can recycling?
Leonard: This is the movie Big Soda doesn't want you to see.
Penny: No, it's the movie your wife doesn't want you to see.

Leonard: So you're actually okay with invading your friend's privacy?
Penny: You're not curious who she's out with?
Leonard: Not really.
Penny: But you're curious about aluminum cans. You're a weird little guy.

Sheldon: Right now, somewhere, a woman is dividing the atomic weight of the best noble gas by the number of colors in the oldest national flag still in use-
Howard: Then using that number as the average speed to calculate the travel time from Mordor to the Shire.
Sheldon: And taking her first step towards a lifetime of laughter, love and, best of all, rules.

Amy: If you don't mind me asking, why did you and your wife split up?
Dave: Oh, you know how it is. We wanted different things. I wanted children, and she wanted a pastry chef named Jean-Philippe.

Amy: Oh, I'm so sorry.
Dave: No, it's fine. It's why I left England. It reminded me too much of her.
Cold, gloomy and easily accessed by a Frenchman through a tunnel.

Bernadette: Hey, you want to swing by that place tonight and get a look at this guy?
Penny: We don't even know what time they're gonna be there.
Bernadette: I'll just call the restaurant, pretend I'm Amy and check the reservation.
Penny: Damn, you're sneaky.
Bernadette: Yeah, but I'm little, so it's adorable.

Sheldon: Are you sure? I've heard that on those sites, often when you think you're corresponding with someone, it's actually a computer program pretending to be a real person.
Raj: And you're afraid it'll do a better job than you?
Sheldon: Excuse me. No one does a better job pretending to be a person than I do. Siri comes close, but I know more jokes.

Howard: If you don't want to use dating Web sites, what do you suggest?
Sheldon: Off the top of my head? Prospective women weed themselves out in a battle of wits until only one champion remains, she shows up at my door flush with the thrill of victory, and then sits quietly by my side while I watch Daredevil.
Howard: You seriously think women would fight for you?
Sheldon: People compete for jobs and trophies, why not me?
Howard: He's right. He knows a lot of jokes.
