Mary: [on the phone] Dr. Linkletter? Mary Cooper.
Dr. Linkletter: Ah, Mrs. Cooper. I assume this is about the upcoming trip and perhaps your very understandable reluctance to let Sheldon come.
Mary: I have to admit I do have some concerns.
Dr. Linkletter: As you should. So, you're saying you'd prefer he not go with us?
Mary: [sighs] But he'd be so disappointed.
Dr. Linkletter: Not more disappointed than me.
Mary: So, you feel good about him going?
Dr. Linkletter: Only if you feel good about it. You're his parent. I'm just an absentminded academic who's never had children.
Mary: Come on, now. You've been such a great help looking after him at college.
Dr. Linkletter: Yes, but college isn't the same as three days in a van.
Mary: Huh. Sheldon can be a nervous traveler.
Dr. Linkletter: Ah. Sounds like you don't want him to go.
Mary: No, I do want him to go. I just want to make sure that you and Dr. Sturgis are okay with it.
Dr. Linkletter: ... We're okay with it. If you're okay with it.
Mary: If you're okay with it, I'm okay with it.
Dr. Linkletter: Then it would seem we're both okay with it.
Mary: Okay.
Dr. Linkletter: Okay.
Mary: Oh, he's gonna be so happy.
Dr. Linkletter: Uh-huh.

Meemaw: Hello?
Dr. John Sturgis: Did you know that word "hello" wasn't used as a greeting - until the invention of the telephone?
Meemaw: Hi, John.
Dr. John Sturgis: To end a phone call, it was suggested to say, "That is all."
Meemaw: Is that all, John?
Dr. John Sturgis: No, I wanted to invite you to dinner tomorrow night.
Meemaw: Great. Where we going?
Dr. John Sturgis: I can't tell you that. It's a surprise.
Meemaw: You want to give me a clue so I'll know how to dress?
Dr. John Sturgis: Well, dress as if you were going to a Mexican restaurant.
Meemaw: Oh, we're going to Puerta Roja.
Dr. John Sturgis: I can't tell you that, it would ruin the surprise.
Meemaw: John, you do realize that I'll be the one driving us there.
Dr. John Sturgis: Fine, we're going to Puerta Roja, but everything else is a surprise. That is all!

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

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.

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.
