Dr. Linkletter: How about some music?
Sheldon: No one likes music. How about a car game? Ooh, I have a fun one where I say a formula, and then you have to say another formula starting with the last letter or number that I said. So, for example, if I said, [Linkletter groans] "X" equals negative "B" plus or minus...
Dr. Linkletter: Music it is. [classical music plays]

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. John Sturgis: Societal norms are different on road trips. Normally, I don't eat junk food, but here, it's tradition. I'm not even sure what a chicharron is.
Sheldon: It's the deep-fried skin of a pig.
Dr. John Sturgis: That seems like something they should say on the bag.

Pat: Look, you seem like nice folk, but Yankees ain't popular around here. I suggest you be on your way.
Dr. Linkletter: Sorry to have troubled you. Let's go.
Sheldon: Excuse me. My colleagues may be from the North, but for your information, I'm a Texan, born and bred. I know that real chili has no beans, and when my meemaw says, "Bless your heart," she means something very different. Now, my friend here is in need of help, and since our state motto is literally "friendship," may he please use your phone?
Pat: Well, dang. [puts the phone on the bar]
Dr. John Sturgis: And could I trouble you for a yellow pages?
Dr. Linkletter: Oh, boy.

Adult Sheldon: After a quick burial behind the bar, we were back on the road. Dr. Sturgis tried to find some appropriate music for a proper send-off. Three Christian talk shows and a whole lot of static later, he settled on what he declared the Dixieland jazz of West Texas. ["El Son de la Negra / Guadalajara" playing] Mariachi.
Dr. John Sturgis: Vaya con dios, armadillo. Vaya con dios.
