Quotes (17)

Raj: Cute is for bunnies. I want to be something with sex appeal. Like a labradoodle.

Penny: Mrs. Cooper? Hey, it's Penny. I think I broke your son. Hold on. Talk to your mother.
Sheldon: (Crying) Mommy, I love you. Don't let Spock take me to the future!

Raj: Dance number aside, I'm so not gay.

Raj: I know the feeling. It's like accidentally walking into a gay bar and then having no one hit on you. It happened to a friend of mine.

Sheldon: Well, I suppose everyone's entitled to their own opinion. I think I'll turn in. I didn't wanna teach those poopy heads anyway.
Howard: FYI, I think that's what Darth Vader said just before he started building the Death Star.

CBS has announced the details for the February 3rd episode of The Big Bang Theory.  Full story


Sheldon is giving a lecture to a class and his condescending manner does not win over the students. Back at the apartment, the rest of the guys are reading the desperate tweets of students in Sheldon's class. When Sheldon arrives home, he is shocked by the reaction to his lecture, which he expected to be extremely positive.

When Raj shows signs of loneliness, Bernadette attempts to comfort and reassure him, but Raj starts to get the wrong idea. Elsewhere, Amy tries to encourage Sheldon after his dismal reception as a teacher. Amy suggests Sheldon should take acting lessons, so he goes over to Penny's and asks her to teach him. Sheldon's first lesson on improvisation stresses out Penny, while the second one breaks Sheldon after he acts out a scence from a Star Trek fan-fiction he wrote as a child.

Raj has a daydream that Howard is offered a fellowship outside the country and requests that Raj fulfil Bernadette's "needs" in his absence. In another day dream, Raj imagines that Howard has been hit by a truck and, for his last wish, wants Raj to take care of Bernadette sexually. His final dream sees an angry Bernadette confront him about his feelings for her, only to descend into a Bollywood dance sequence.

This episode was definitely a lot different, we get to see a different side of Sheldon, a softer side. He doesn't seem as much like a robot.

I thought this was one of the best episodes. All the characters made the storyline come alive as usual. I thought that "Bollywood" fantasy sequence with Raj and Bernadette was killer, I still thought about for a while after it ended.

The bit where Sheldon is playing his Mother and says "I love you Shelley even though you creep the be-jesus out of me" nearly made me wet myself!!!!!

I only liked the part where Sheldon is taking acting lessons from Penny, the rest was okay I guess but nothing special...

This episode had a big flaw! Wolowitz says "I think that's what Darth Vader said before building the Death Star." Darth Vader didn't build the Death Star! Come on. He was sent to kick some butt to get it built. He is even shown as saying, "Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force." Wolowitz, for shame! FOR SHAME!
