Dr. Linkletter: Do you remember when we came up with the idea for that grant database?
Sheldon: I remember when I came up with the idea.
Dr. Linkletter: Uh, in my office.
Sheldon: In my brain.
Dr. Linkletter: Which was in my office. And, as I recall, I was the one who suggested you build a database.
Sheldon: No, you suggested I build a comic book database.
Dr. Linkletter: Which was the underlying idea.
Sheldon: Fire is the underlying idea for the nuclear power plant, and no one credits the caveman.
Dr. Linkletter: Son, and I call you son because I think of you as family. [Sheldon smiles] Is this the way you would treat your own family?
Sheldon: Not my mom. Everyone else is on their own.

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.

Dr. Linkletter: Sheldon, thank you for coming in. I want to apologize for our little tiff earlier.
Sheldon: You're forgiven.
Dr. Linkletter: Oh. Great. I found something that might be of interest to you. An authentic signature from Richard Feynman.
Sheldon: Where did you get this?
Dr. Linkletter: Details aren't important.
Sheldon: Is this a restraining order?
Dr. Linkletter: Not important.
Sheldon: That's actually a really good way to get autographs. I'll have to keep that in mind.

Georgie: Dang, it's busy in here for a weekday.
Meemaw: Social Security checks landed.
Georgie: Hm. Getting paid just to be old... must be nice.
Meemaw: I ain't complaining.

Mrs. Howard: I can't believe you would rent this filth.
Mandy: It's not filth. It's Basic Instinct.
Mrs. Howard: Well, my husband was watching it and there was a woman in there who showed her hoo-ha.
Georgie: Yeah, she does.
Mandy: Come on, I mean, you don't see the whole thing. At most, you see a "hoo."
Georgie: If you see the "hoo," the "ha's" right there.
