Sheldon: But there was a note on file. If one became available, it was supposed to be held for me.
Missy: Sorry.
Sheldon: But there was a note on file.
Missy: I didn't see a note.
Sheldon: Did you even check the file?
Missy: I can't help you. The comic is gone.
Sheldon: Well, who'd you sell it to?
Missy: I don't know, some guy.
Sheldon: Which guy?
Missy: Some weird guy.
Sheldon: That doesn't narrow it down, and you know it.

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.

Sheldon: Too bad there's not a comic book database so I could search through it and find what I'm looking for.
Dr. Linkletter: Well, CERN has something similar. You can search a database of scientific papers.
Sheldon: But there's no database for comic books.
Dr. Linkletter: You should make one. Somewhere else.
Sheldon: Mmm, sounds like a lot of work.
Dr. Linkletter: Or does it sound like a lot of fun? Go find out.
Sheldon: Do you want to do it with me?
Dr. Linkletter: Only if you share credit, and my name comes first.
Sheldon: Never mind. [exits]
Dr. Linkletter: I knew that would work.

Adult Sheldon: In the world of collecting, I'm what's known as a completist. For example, I own every gauge of model train from the mighty "G," to the tiny "T." Look at how cute it is, I just want to eat it up. However, the downside of being a completist is when something's missing, it's like an itch you can't scratch, even if you own a complete set of Justice League back scratchers... which I do. In this case that itch was the comic book issue Doom Patrol and Suicide Squad Special #1.

Georgie: Were you mad at Mom for getting pregnant?
Meemaw: Oh, yeah.
Georgie: Did you stop talking to her?
Meemaw: Hell no, I wanted her to hear how pissed off I was. But all that being mad at her just was a waste of time.
Georgie: What made you come around?
Meemaw: I guess you showing up.
Georgie: I do have a natural charm, don't I?
Meemaw: You did, and then you learned to talk.
