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.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George Sr.: Talked to Billy.
Missy: Why would you do that?
George Sr.: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Visiting Tam's house for the first time was an emotional roller coaster.
For example, it's traditional in Vietnamese homes to have gruesome religious iconography near the entrance. I did not like that.
However, it's also customary to not wear shoes around the house for sanitary reasons. I did like that.
Interestingly, one of the main ingredients in Vietnamese cooking is an extremely pungent condiment known as fish sauce. I did not like that.
But before every meal, it's common for everyone to wash their hands and face. I did like that.
Forks are not customary in a Vietnamese household. I did not like that.
And instead of napkins, there was one towel for everyone to share at the table. Seriously, what are they thinking?

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.

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.

Dr. John Sturgis: I'm doing it. This is going quite well.
Dr. Linkletter: Feel free to pick up the pace. A butterfly just passed us.
Dr. John Sturgis: Well, what's the speed limit?
Sheldon: 75.
Dr. John Sturgis: And I'm going... ten. I'll pick up the pace.
