This episode establishes that Raj can talk to women while drunk.
The Koothrappalis revealed that Raj is 26 years old.
Leonard: Do you really need the Honorary Justice League of America Membership card?
Sheldon: It's been in every wallet I owned since I was five.
Sheldon: It says, "keep this on your person at all times." It's right here under Batman's signature.
Sheldon: I'll have a diet Coke.
Penny: Can you please order a cocktail? I need to practice mixing drinks.
Sheldon: Fine... I'll have a virgin Cuba Libre.
Penny: That's... rum and Coke without the rum.
Sheldon: Yes, and would you make it diet?
Raj: (drunk) Where did my life go, Penny?
(everyone is shocked)
Raj: One day, I'm a carefree bachelor, and the next, I'm married and driving a minivan to pee-wee cricket matches in suburban New Delhi.
Penny: Are you talking to me?
Raj: Is there another Penny here?
Penny: I need some guinea pigs.
Sheldon: Okay, there's a lab animal supply company in Reseda you can try. But if your research is going to have human applications, may I suggest white mice? 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.
Sheldon: When I was a little boy and got sick, which was most of the time, my mother would read [The Monkey and the Princess] to me. It's about an Indian princess who befriends a monkey who was mocked by all the other monkeys because he was different. For some reason I related to it quite strongly.
Penny: I know the reason.
Leonard: We all know the reason.
Penny: (to Raj about Lalita) No one can make you get married. Why don't you just meet this girl and see what happens?
Raj: Haven't you been listening to me? I cannot talk to women!
Leonard: Um, Raj?
Howard: No, no, let's see how long it takes him.
Wolowitz: Is it just me, or does webchatting with your clothes on seem a little pointless?
Leonard: Look at the bright side. [Lalita] might turn out to be a nice, beautiful girl.
Raj: Great, then we'll get married, I won't be able to talk to her, and we'll spend the rest of our lives in total silence.
Wolowitz: Worked for my parents.
Sheldon: Why would I see [Lalita] again? I already have a dentist.
Leonard: (to himself) I wonder who's going to tell his parents that they're not having grandchildren.
Penny: Here you go, Leonard, one Tequila Sunrise.
Leonard: Thank you. You know this drink is a wonderful example of how liquids with different specific gravities interact in a cylindrical container.
(Penny looks scornfully at him)
Leonard: (humbly hushed) Thank you.
Raj: I had such plans. I had dreams. I was going to be the Indira Gandhi of particle astrophysics... but with a penis, of course.
Raj: How can I be a gynocologist? I can barely look a woman in the eye!
(Sheldon drunkenly sings a Jewish folk song)
Leonard: What got into him?
Penny: Oh, just a couple virgin Cuba Libres that turned out to be kinda slutty.
Sheldon: You are the living embodiment of the beautiful Princess Panchali.
Lalita: Oh, no kidding? Who is that?
Sheldon: A beloved character from an Indian folktale.
Lalita: Oh. 'Us' Indian or 'Come to our casino' Indian?
Sheldon: 'You' Indian.
Sheldon: I shower twice a day and wash my hands as often as I can.
Lalita: Really? So do I!
Raj: But you're a dentist; he's nuts.

The text presented on the Chuck Lorre Productions logo card (#195) read simply "United we stand," expressing the producer's solidarity with the Writers Guild of America, which was striking at the time of first broadcast.
Sheldon's honorary Justice League of America Membership card refers to the team of superheroes from the DC Comics universe, originally formed by Batman, Wonder Woman, Superman, Flash, Green Lantern, Aquaman, and Martian Manhunter.
