The Transporter Malfunction

Quotes (20)

Leonard: Once you open the box it loses its value.
Penny: Yeah, yeah. My mom gave me the same lecture about my virginity. I gotta tell you, it was a lot more fun taking it out and playing with it.

Sheldon: I thought where you come from they don't have emotions.
Spock Doll: I come from a factory in Taiwan.

Leonard: You went to the comic book store by yourself?
Penny: Yeah, it was fun. I walked in and two different guys got asthma attacks. It felt pretty good.

Raj: No, I'm not gay. If anything, I'm metrosexual.
Dr. Koothrappali: What's that?
Raj: It means that I like women, as well as their skin-care products.

Penny: What is the truth?
Sheldon: My Mr. Spock doll came to me in a dream and forced me to open it. And when the toy broke I switched it for yours. Later, he encouraged me to do the right thing and I defied him. And then I was attacked by a Gorn.
Leonard: Okay, that I believe.

CBS Announces Episode 5.20: Leonard Nimoy guests March 12, 2012

CBS has announced the next episode of The Big Bang Theory, which will air Thursday, March 29, 2012. Legendary Star Trek actor Leonard Nimoy voices Mr. Spock in the episode.  Full story


As the gang eat dinner in the apartment, Howard presses Raj about who he's bringing to the wedding. Raj is cagey about whether he'll be bringing a plus one. Later, Raj video chats with his parents asking them to set him up on a date. Back in the apartment, Penny arrives with gifts for Sheldon and Leonard as a thank you for all the help they've given her. The guys' gifts are mint-in-box 1975 Star Trek transporters. The guys are thrilled with their gifts, though Penny is disappointed when they say they won't actually be opening the rare collectibles.

Raj is with Howard and Bernadette at a restaurant awaiting the arrival of his blind date, Lakshmi. Later, as Sheldon works at his desk, he begins to hear the voice of Spock speaking to him. Spock tells him the only logical conclusion is this is a dream and that he should wake up and play with his toy. Sheldon unpacks the toy and begins to play with it but the transporter jams. Sheldon notices Leonard's toy and realizes it's the only logical solution. Elsewhere, in Raj's apartment, Raj and Lakshmi are enjoying desert together. They realize their parents are probably wondering how the date is going. Before they update their parents, they decide they should make sure they're on the same page. Lakshmi reveals that she is feeling a lot of pressure to settle down and have a family, and that she went on the blind date so they don't find out she's gay. Raj is surprised to hear Lakshmi is gay and even more surprised when she figures he is, too. Lakshmi is disappointed as Raj would be the perfect phoney-baloney husband.

Sheldon is turning in bed and then wakes up on an alien planet. The tiny Spock toy is talking to him again, chastising him for breaking the toy and switching it with Leonard's. Sheldon blames Spock for telling him to play with the toy. Sheldon throws the Spock toy away and is then attacked by a gorn. Sheldon wakes up in bed. Later, in Howard's lab, Raj confides in Howard that Laskhmi is gay and he is seriously considering going through with the sham marriage. Raj says marrying Lakshmi would get his parents off his back, give him somebody to come home to every night, and allow him to finally eat carbs again and let himself go. Howard does not think Raj should settle for a fake relationship.

Sheldon tries to switch the Spock boxes back around but realizes he doesn't want a broken toy. When Leonard and Penny arrive home, she convinces him to play with his toy. When Leonard opens it to find it's broken, Penny is angry that Stuart sold her a faulty item. Sheldon starts telling lies about how the Spock toy was broken, but each time he admits it's a lie. Eventually he tells them the truth that he opened the toy, broke it and switched it with Leonard's. Later, Howard and Bernadette stop by Raj's with a puppy for him.

i watched an episode last night where everyone was in the lounge room talking about the upcoming wedding, and raj was openly talking to everyone including the girls, without him drinking. and then he had an arranged date with another indian girl (who turns out to be lesbian), but raj didn't have to drink to talk to her either. since when did raj start talking to girls freely??

I love Sheldon's "that's a lie". It should become natural for him, like "Bazinga!" or "knock, knock, knock " Penny!"" The part with Spock's voice was amazingly funny and entirely Sheldon Cooper. Every Sheldon Fan will agree with these dreams for him, as they represent his opressed emotions. I don't think Lakshmi and Raj should marry. Although I belive, that their parents would be overjoyed and they would be really good parents (because they have no other than friendly feeling for each other, the would'nt fight about emotional things and therefore lead a harmonical marriage, in which children would grow up steadily and open minded), Raj shouldn't marry her. He states, that he is heterosexual, and therefore I think, it should be possible for you, to introduce him to a girl, that loves him the way he is (caring, feely-touchy and faithful), even if it is an arranged marriage to which he may not agree at first sight. This could be an enthralling sidetrack of the main theme (Penny-Lennard-Sheldon) your's truly, a SheldonXPenny Fan
