Mary: How's it going, baby?
Sheldon: I don't think anyone's showing up, not even Tam.
Mary: I'm here.
Sheldon: Yeah, but you're my mom. You live on the premises. At least Dr. Sturgis should be here any minute.
Mary: Shelly, I'm afraid Dr. Sturgis isn't coming this morning.
Sheldon: Why not?
Mary: He isn't feeling well.
Sheldon: Oh, dear. Should we send him a get well card?
Mary: I think that'd be terrific.

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.

Meemaw: John?
Dr. John Sturgis: Hello.
Meemaw: What- What're you doing?
Dr. John Sturgis: I was doing tai chi and then I realized that I was continually being bombarded by subatomic particles and it behooves me, perhaps, to pay slightly closer attention to them. Maybe "chi" is the ancient Chinese word for the subatomic universe.
Meemaw: You're scaring me, John.
Dr. John Sturgis: Well, there's nothing to be scared of. Tomorrow, somebody will win the Nobel Prize about these particles not me. But I'm experiencing them firsthand [LAUGHS] which could be better.
Meemaw: Why don't you come down and experience them on the floor?
Dr. John Sturgis: I think I just felt a neutrino. [LAUGHING] You know, neutrinos are interesting. They never bond with anything, they're always alone. I think that one went right through my pants.
Meemaw: All right, why don't we go downstairs, and I'll fix us both a nice cup of hot tea and you can tell me all about it. Please?
Dr. John Sturgis: Okay. It was my dream to win the Nobel, and I'm not going to. I bet Sheldon will.
Meemaw: That'll be something.
Dr. John Sturgis: Yeah.

Adult Sheldon: A primary feature of quarks is that they're always bonded together, but in that moment, I felt like a neutrino, destined to be alone forever.
[Montage of young Leonard, Penny, Raj, Howard, Bernadette and Amy at that moment]
Adult Sheldon: Thankfully, I was wrong.

Georgie: A bill? Really?
George: Room and board, buddy.
Georgie: $50 a month for food?
George: The way you eat, I should've gone $50 a week.
Georgie: Laundry services?
George: Your poor mother has to touch your underwear.
Georgie: What's the $10 a month "peema" charge?
George: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.
