  • Quotes (16)

    • Sheldon: Engineering—where the semi-skilled laborers execute the vision of those who think and dream.

    • Koothrappali: Do you know what he did? He watched me work for ten minutes and then started to design a simple piece of software that could replace me. Leonard: Is that even possible? Koothrappali: As it turns out, yes.

    • Leonard: You always knew that someday someone would come along who was younger and smarter. Sheldon: Yes, but I assumed I would have been dead hundreds of years and that there'd be an asterisk next to his name because he'd be a cyborg.

    • Leonard: (to Sheldon on Dennis' superior intelligence) So what are you gonna do, just give up? Sheldon: Yes. That's what any rational person would do when his entire life's work is invalidated by a post-pubescent aged wunderkind. He ceases his fruitless efforts, he donates his body to scientific research, and he waits to die. (Sheldon leaves the room) Penny: You know, I'm confused again. Is he waiting, or do we get to shoot him between the eyes?

    • Leonard: You speak English really well. Dennis: So do you... except for your tendency to end sentences with prepositions. Leonard: What are you talking about? Dennis: That. Sheldon: He's not wrong.

    Trivia (4)

    • This is the first time we see the inside of Sheldon's office.

    • When Sheldon first discussed with Leonard about his work, there was a notebook besides the laptop. It was lying flat on a maroon folder. After Sheldon asked Leonard if Leonard usually worked based on hunches and guesses and stuff, the camera changed angle and notebook has fallen slightly off the folder instead of lying flat on it. However, both of them did not move anything significantly to make the notebook shift its original position.

    • We learn Sheldon's middle name is Lee, according to his Stevenson award.

    • We learn Howard holds a Masters degree in engineering.

    Allusions (5)

    • Sheldon uses the phrase, "Curiouser and curiouser," a line borrowed from Alice in Lewis Carroll's Alice's Adventures in Wonderland".

    • Sheldon says of his planned Mexican reproduction of Jerusalem that it'll be, "like that baseball movie, 'build it and they will come'," referring to Phil Alden Robinson's 1989 film Field of Dreams, based on W.P. Kinsella's 1982 novel, Shoeless Joe.

    • Informed that Dennis has agreed to join the university, Sheldon exclaims, "the oracle told us little Neo was the one," borrowing from the Wachowski brothers' 1999 film, The Matrix. Afterwards Sheldon makes a movement with his hands mimicking the falling letters pattern that visualizes the Matrix.

    • Sheldon refers to engineers as the "Oompa-Loompas of science", borrowing from the fictional creatures who were the only ones allowed by Willy Wonka to do work in Roald Dahl's 1964 book, Charlie and the Chocolate Factory.

    • Sheldon says, "I sense a disturbance in the Force," followed by Leonard imitating Yoda by saying, "A bad feeling I have about this," actually parodying Han Solo's oft-quoted "I have a bad feeling about this," from George Lucas' 1977 film, Star Wars.
