Leonard Hofstadter
- 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.
- 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 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.
