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.

Raj's father is played by a veteran actor, Brian George. Of course, he is vest remembered as Babu from Seinfeld, who ended up being deported to Pakistan. Then he was the finale as well, Anyways, Brian worked and lived in Canada for a few years. He was in thus recurring sketch on a comedy show called Bizarre with John Byner. The sketch was called The Bigot Family. Air Farce member Luba Goy was also in the sketch. Brian played an Italian character. He is really good at different dialects. He's quite a talented actor. Bizarre was on in the 80s mainly. Super Dave Osborne creator Bob Einstein was a star and a producer in the show.

When Howard makes Raj's date for him, he sounds like Peter Sellers' Hrundi V. Bakshi from the Blake Edwards movie THE PARTY.

I don`t know if anyone else had ever asked before but could someone please tell me what Sheldon is singing at the 2nd verse? To my knowledge, the lyrics of the song do not include words like "lucky", "Monday" or "Sunday" - and these are a few words I suppose to recognise... Nevertheless, Jim Parsons is a great musician and singer! Not to forget his fabulous acting skills... Great job!
