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]

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Are we in my office?
Sheldon: No.
Dr. Linkletter: Then these are not my office hours.
Sheldon: Are you using my love of schedules against me?
Dr. Linkletter: [chuckles] Oh, yes.
Sheldon: Well done.

Sheldon: Dr. Linkletter, I need to talk to you.
Dr. Linkletter: Great.
Sheldon: Do you think you could get me access to the telescope room? I want to search for exoplanets that could support life.
Dr. Linkletter: Are you feeling homesick?
Sheldon: Are you implying that I'm from another planet?
Dr. Linkletter: Yes.
Sheldon: Compliment accepted.

Sheldon: Now, about the telescope room, I was watching Star Trek and it got me thinking...
Dr. Linkletter: Sheldon, searching for life on other planets isn't serious science. Leave that to the tinfoil hat brigade.
Sheldon: But statistically, given the number of stars and planets, it's likely we could find one capable of supporting life. And if we did, it would be the greatest scientific discovery of all time.
Dr. Linkletter: Yes, and if I had fruit on my head, I'd be Carmen Miranda.
Sheldon: I'm not familiar with that reference.
Dr. Linkletter: She sang and danced with fruit on her head.
Sheldon: Why would she have fruit on her head?
Dr. Linkletter: I don't know, in case she got hungry. It's not gonna happen, Sheldon!

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.
