Mikayla: You want the girlfriend experience.
Leonard: Yes, yeah, exactly, the girlfriend experience.
Raj: Uh, actually, if it's not too much to ask, could we have the Jewish girlfriend experience.

Sheldon: I was Spock. Are you and Leonard friends with benefits?
Penny: What?
Sheldon: Are you and Leonard friends with benefits?
Penny: Where did that even come from, did he say we were?
Sheldon: No, Leonard said nothing, but who knows what goes on over here when he pretends your mail was mis-delivered.
Penny: No, just mail, no benefits.

Sheldon: Okay, that's question 20, you have to guess.
Penny: Oh, God, I don't know Sheldon, are you Star Wars?
Sheldon: How can one person be a whole movie?

Leonard: Alright, back to the game.
Sheldon: I believe it's my turn, you may begin your questions whenever you're ready.
Raj: Are you Spock?
Sheldon: I don't like this game.

Raj: What's wrong with you dude, that woman was all up in my jammy.
Leonard: Okay, I hate to break this to you and whatever your jammy is, but, I'm pretty sure she is a prostitute.
Raj: What? No.
Leonard: Okay, let me put it this way, in your entire life, how many gorgeous women have walked straight up to you in a bar and asked if you wanted to party.
Raj: Maybe I can save her.
Leonard: Maybe, but I'm guessing it will cost you about $500 an hour to try.
Raj: It was lovely meeting you, best of luck in your future endeavors.

Penny: Alright, Sheldon, let's just calm down and we'll call the building manager, he'll come open your door, you just eat your dinner here while you're waiting.
Sheldon: Eat? My dinner? In your apartment?
Penny: Yeah, why not?
Sheldon: Sure, why not? And after the sun's down we can all pile in my pick-up and go skinny-dipping down at the creek. 'cause today's the day to stop making sense.

Leonard: Look, imagine you maintained a friendship with someone you had sex with, but you were free to date whoever you wanted.
Sheldon: I'm sorry, I can't imagine any of that.

Leonard: Howard, could I borrow some after shave?
Howard: Black case, top compartment.
Leonard: That is a lot of cologne.
Howard: First row are your musks, second is wood, leathers and botanicals, third is assorted pheromones, tread lightly.

Penny: Hang on, I think the emergency key is around here somewhere.
Sheldon: We have a bowl. Our keys go in a bowl. You should get a bowl.
Penny: So, how did the beautiful mind of Sheldon Cooper forget his key in the first place.
Sheldon: I left them in the bowl.

Howard: Okay, are you from Star Wars universe?
Leonard: Yes.
Howard: Were you in the original trilogy?
Leonard: Yes.
Howard: Is there a picture of you in my wallet wearing a metal bikini?
Leonard: God, I hope not. And no, I'm not Princess Leia.

Raj: What happened with Leslie, why did she dump you?
Howard: I don't know. She just said Howard, momma's a rolling stone. And then her call waiting beeped and she was gone.
Sheldon: I don't understand. If you were in a non-emotional relationship then why are you having what appears be an emotional response?
Leonard: Sheldon, he obviously had feelings for her.
Howard: Of course I had feelings for her, I saw her naked for God's sake!

Raj: Oh, we should have a plan in case one of us gets lucky.
Leonard: Okay, uh, if I get lucky I'll take her to my stately manor outside Gotham City, and if you get lucky, I'll sleep on the moon.
Raj: Sounds like a plan.

Stuart: Yeah, last night at dinner, I did what you told me, I went really slow, I kept my distance, and two bottles of wine later, we were making out in my car.
Leonard: Wine? I didn't say to give her wine.
Stuart: It doesn't matter, that's where it all went to hell.
Leonard: During the kissing? What did you do, sneeze in her mouth? I did that to a girl once.
Stuart: No, everything was good and really hot, and I said “Oh, Penny,” and right where she was supposed to say, “Oh, Stuart,” she said ... your name.
Leonard: Leonard?
Stuart: That is your name, right?
Leonard: Yeah, no, yeah, wow, I'm sorry. That must've been the last thing you wanted to hear.
Stuart: Well, it beats "You know I'm a dude, right?" Yeah, it was pretty bad.

Leonard: Hey, Stuart, I need to talk to you.
Stuart: Sure, what's up?
Leonard: I think I gave you bad advice about Penny, and I want to apologize.
Stuart: No, your advice was great.
Leonard: It was?
Stuart: Yeah, going slow really worked.
Leonard: You're kidding. Never worked for me.

Howard: (talking on the phone) Yes, sir, I understand classified. We'll keep it all classified, no one has to know but you and me.
Penny: What's classified?
Leonard: Howard's space toilet. I'll tell you later.
