Sheldon: Here you go. 473 grease-free bolts.
Dr. Linkletter: Excellent.
Sheldon: Now what? How about I help you design an even better solar neutrino detector?
Dr. Linkletter: Actually, what I need you to do is... take this grease and put it on these bolts.
Sheldon: But I just took the grease off the bolts.
Dr. Linkletter: That was the wrong grease. This is the right grease. Have at it.
Sheldon: If this is some kind of test to get me to quit, it's not going to work.
Dr. Linkletter: I don't know what you were expecting, but this is a menial job. After this, I need you to sort a crate of resistors, strip a case of wire and then sweep up.
Sheldon: Oh. Then I quit.

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: "Ergo"?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Mary: Too bad. We are going.
Sheldon: Class is starting tomorrow. I'm not going anywhere.
Mary: Sheldon, do not argue with me. You are going home.
Sheldon: Mom, the people of Germany are obsessed with rules and devoid of humor. I am home.

Georgie: What is this?
Meemaw: That's the exercise guy Meemaw likes.
Georgie: I can't believe anyone pays money to watch old people sweat.
Missy: 40 bucks?
Georgie: They sold over a million of those? At 40 bucks a pop? Do you know how much money that must be?
Missy: I'm not a calculator.
[later:]
Georgie: 40 times... one million. That's 40 million!
Missy: Whoa.

Adult Sheldon: Behind every great scientist, there were often unsung helpers toiling away in the background. Presenting... "Great Lab Assistants in Scientific History" When Alexander Graham Bell needed an assistant, it was Thomas Augustus Watson who answered the call. [laughs] Get it? "The call". [snickers] Madame Curie's daughter Irène was also her lab assistant. Irène was so dedicated, she died of radiation poisoning. Unlike her sister Ève, who selfishly lived to 102. Lastly, Émile Roux was assistant to Louis Pasteur. When they worked on the rabies vaccine, Roux kept a loaded gun in the lab to shoot Pasteur in the head if he got infected. He never had to, but it's fun to know he would have.
Dr. Linkletter: No, Sheldon. You can't be my lab assistant.
Sheldon: Maybe you weren't paying attention. I'll start over. Behind every great scientist, there was a dedicated as...

Adult Sheldon: While not the lab work I hoped to be doing, it did feel good to be part of an actual experiment. A tedious, menial part that could be performed by a monkey. Or worse, an engineer.
