  • [last lines]
  • Leonard: [Sheldon is singing "L'Chaim" at Penny's bar] I can't believe it! What got into him?
  • Penny: Oh, maybe a couple of virgin Cuba Libres that turned out to be kinda slutty.
  • Leonard: You didn't.
  • Penny: Hey, you do your experiments, I do mine.
  • Raj Koothrappali: [Raj walks in Leonard and Sheldon's apartment holding his laptop open, with his parents on the screen via a webcam] Leonard, may I present, live from New Delhi, Doctor and Mrs Vyan Koothrappali.
  • Leonard: [waves cheerfully] Hi!
  • Dr. Koothrappali: Lift up the camera! I'm looking at his crotch!
  • Penny: I need some guinea pigs.
  • Sheldon: O-kay, there's a lab animal supply company in Reseda you could try. But if your research is going to have human applications, may I suggest white mice instead; their brain chemistry is far closer to ours.
  • Penny: I swear to God, Sheldon, one day I'm going to get the hang of talking to you.
  • Leonard: His mom's been saying that for years.
  • Leonard: Well Penny, we'd love to help you, but Raj is going through some stuff right now, besides, he doesn't drink, so.
  • Leonard: [Raj whispers in Leonard's ear, Leonard responds] Really?
  • Leonard: [to Penny] Um, Raj is going through some stuff right now, and he'd like to take up drinking.
  • Leonard: Okay, now do you really need the Honorary Justice League of America membership card?
  • Sheldon: It's been in every wallet I've owned since I was five.
  • Leonard: Why?
  • Sheldon: It says, "Keep this on your person at all times". It's right here under Batman's signature.
  • Raj Koothrappali: [to Sheldon] If you do not stop hitting on my lady, you will feel the full extent of my wrath!
  • Leonard: I'm not hitting on her!
  • Lalita: And I am not your lady!
  • Wolowitz: And you have no wrath.
  • Raj Koothrappali: Go ahead, tell my parents why they won't have any grandchildren.
  • Sheldon: How would I know? Do you have a low sperm count?
  • Raj Koothrappali: This has nothing to do with my sperm count.
  • Mrs. Koothrappali: You are wearing the boxers that we sent you, aren't you?
  • Raj Koothrappali: Yes, Mumi.
  • Mrs. Koothrappali: Because you know what happens to the samosas when you wear tighty-whities.
  • Raj Koothrappali: Can we please stop talking about my testicles? Sheldon, tell them what you did.
  • Sheldon: What did I do?
  • Leonard: You left with his date. Friends don't do that to each other.
  • Leonard: The key to acquiring proficiency in any task is repetition.
  • Sheldon: With certain obvious exceptions. Suicide, for example.
  • Leonard Hofstadter: I don't believe it. What's gotten into him?
  • Penny: Oh, just a couple of virgin Cuba Libres that turned out to be kinda slutty.
  • Leonard Hofstadter: Wait a minute. What's the plan here? Lets say he meets her, he likes her, they get married. What's he gonna do, stay drunk for the rest of his life?
  • Howard Wolowitz: Worked for my parents.
  • Raj Koothrappali: [after Sheldon leaves with Lalita] What just happened?
  • Leonard Hofstadter: Beats the hell out of me.
  • Howard Wolowitz: I'll tell you what happened. I just learned how to pick up Indian chicks.
  • Leonard Hofstadter: So you're not going to see her again?
  • Sheldon Cooper: Why would I see her again? I already have a dentist.
  • Raj Koothrappali: Haven't you been listening to me? I cannot talk to women!
  • Leonard: ...Um, Raj...
  • Wolowitz: No no, let's see how long it takes him.
  • Penny: Raj, you say you can't talk to women, but you've been talking to me!
  • Sheldon: And now we'll never know.
