Dr. Edward Pilson: Okay, Sheldon, this first battery of tests measures basic problem-solving abilities.
Sheldon: Is the Kaufman test or the Wechsler Intelligence Scale?
Dr. Edward Pilson: Are you familiar with those?
Sheldon: It's embarrassing, but I enjoy a little light reading in the bathroom.

Mary: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

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.

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Dr. John Sturgis: So, some colleagues of mine at the university are doing a research study on twins. I told them about Sheldon and his sister, and they were most intrigued.
George Sr.: Uh, what kind of study?
Dr. John Sturgis: It's a longitudinal investigation of environmental and genetic factors in the development of cognitive and other capacities in pairs of fraternal and identical twins.
Meemaw: You asked.

George Sr.: Listen, why don't we just go there this Saturday and give it a try?
Mary: And if you don't like it, we don't have to do it again.
George Sr.: Or they'll love it, and they'll do it till they're 18, 19 years old.
Sheldon: I already love it.
George Sr.: My man. Missy? I believe there might be a Dairy Queen on the way there.
Missy: Can I get an Oreo Blizzard?
George Sr.: You know what I think? I think you're smarter than him.

George Sr.: Well, geez, I don't I don't know if I want some scientists pokin' and proddin' the kids.
Meemaw: Oh, but they wouldn't be poked and prodded. They just have to, you know, answer some questions.
Dr. John Sturgis: And maybe some puzzles and tests.
George Sr.: That's not too bad. Where is it?
Dr. John Sturgis: Houston.
George Sr.: Oh, it just got bad. That's that's a long drive.
Dr. John Sturgis: It does pay $50 an hour plus gas and expenses.
George Sr.: Really?
Meemaw: I told you to start with that.
