Adult Sheldon: During that time, I saw three cars drive by and a raccoon dragging a slice of pizza.

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?

Meemaw: This is delicious, but you were not kidding about the spice. I'm about to break a sweat here.
Dr. John Sturgis: Well, here's something you might find interesting. Spicy food is typically found in warmer climates because it induces sweating, which in turn, cools people off.
Meemaw: So what does the runny nose do for me?
Dr. John Sturgis: It allows me to, uh, gallantly offer you my handkerchief.
Meemaw: You are such a gentleman.
Dr. John Sturgis: When I was younger, I read a book on etiquette. That's how I know that if I ever have an audience at the Vatican, I should wear evening attire or a sack coat.
Meemaw: I don't know what a sack coat is, but I'm sure you'd look handsome in it.
Dr. John Sturgis: Thank you.

George Sr.: So, Dr. Sturgis, Sheldon tells us you're a guest professor at the university.
Dr. John Sturgis: I am.
Mary: Hmm. Does that mean that you're only here temporarily?
Dr. John Sturgis: Well, that's the plan for now. But I could be enticed to stay.
Sheldon: Meemaw, I do believe there was subtext there. Did you pick up on it?
Meemaw: Yeah.
Sheldon: Was I correct to infer there was subtext there?
Dr. John Sturgis: You were.
Sheldon: Okay, we're all good.

Dr. John Sturgis: You weren't kidding. Spaghetti and hot dogs is delightful.
Sheldon: Even better since Mom perfected the chunk ratio.
