David: [on the phone] Okay, so what we're gonna need to do is wipe your hard drive clean and reinstall the operating system.
Sheldon: What about all my files?
David: Do you have everything backed up?
Sheldon: I back up my files every Thursday night. I call it Backup Thursdays. It's not the catchiest, but it sums up the situation.
David: Perfect. After we wipe your drive, you can restore it, and you'll be good as new.
Sheldon: Thank you so much.
David: No problem. So, start by turning the computer off and inserting the DOS disk.
Sheldon: Wait, what if I used the backup disk after the virus was already on the computer?
David: Oh. Uh, then I'm afraid it's corrupted, too.
Sheldon: But how do I get my files?
David: You don't.
Sheldon: But I have all my old papers on there, my parents' taxes.
David: I'm sorry.

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.

Adult Sheldon: Like a virus, heartbreak can also spread. Once it does, it's hard to contain. In some cases you can try to reboot and start over. But it makes you appreciate those early days, when your hard drive was clean... and the world was full of possibility.

Meemaw: So how come it's taken us so long to hang out?
Brenda Sparks: Well... my husband never left me before.
Meemaw: We can joke about it? Good. 'Cause that's gonna make this night way easier.

Mary: So, then, was there no big blowup when he left?
Brenda Sparks: Not really.
Mary: Well, what happened?
Brenda Sparks: Let's see... We used to be happy. Little by little, we weren't. Then there was bickering, then there was silence, and then... it was over.
Mary: I mean... all couples bicker, right?
Meemaw: You worried about you and George?
Mary: Of course.
Brenda Sparks: I'm sure you guys will be fine.
Meemaw: And if it doesn't work out, I'd be happy to introduce you to Butt Crack Bob over here. [laughs]
