Quotes (30)

Leonard: I don't believe it. What's gotten 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 little experiments, I do mine.

Raj: How can I be a gynaecologist? I can barely look a woman in the eye!

Sheldon: How often does one see a beloved fictional character come to life?
Wolowitz: Every year at ComiCon. Every day at Disneyland. You can hire Snow White to come to your house. Of course they prefer if you have a kid.

Penny: I finally convinced the restaurant to give me a bar-tending shift, so I need to practice mixing drinks.
Leonard: That's Great! The key to acquiring proficiency in any task is repetition.
Sheldon: With certain obvious exceptions. ... Suicide, for example.

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's parents have set him up on a blind date. When Raj is unable to call her to arrange the details, Howard impersonates Rajs and sets a date for Friday. Penny comes over to the apartment and tells the guys she needs to practice mixing drinks, so she wonders if they would like to serve as her "guinea pigs". As Penny mixes drinks for the guys, they discover that Raj can talk to women under the influence of alcohol.

When Raj uses his newfound ability to talk to women, he ends up drunk and obnoxious on his date with Lalita Gupta. Sheldon turns up at the restaurant and describes Lalita as the embodiment of his beloved children's character "Princess Panchali" from the "Princess & the Monkey" book. Lalita is charmed by Sheldon's description of her and leaves Raj to have dinner with Sheldon.

Back in Sheldon and Leonard's apartment, Raj tries to explain to his parents via video chat why his date went wrong, blaming Sheldon. When Sheldon returns home, he can not see how he ruined Raj's date. Later, Sheldon is singing at the Cheesecake Factory under the influence of a Virgin Cuba Libre that turned out to be a little slutty.
