Sheldon: [knocks on door] Missy, I know you're upset. Would you like a hot beverage?
Missy: [o.s.] Go away.
Adult Sheldon: Every culture has their taboos. In the Ukraine, it's rude to whistle indoors, and they're correct. Not a fan. In our society, any discussion of human reproduction seems to be so upsetting, it causes nothing but chaos. Lost jobs. Lost friends. Sleepless nights. Even the word "sex" provokes an uncomfortable reaction. I thought "fornicate" might work, but that seemed too judgy. Then I found the perfect word, a word so bland and clinical that it would be impossible to take offense to it.
Sheldon: "Coitus." That'll work.

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?

Sheldon: And then Missy said it was embarrassing to talk to our mother about reproduction.
Dr. John Sturgis: Interesting, yet the two of you are living proof she has at least a working knowledge of the subject.
Sheldon: That's what I said, then Missy said something's wrong with me.
Dr. John Sturgis: Oh, I think you're as normal as I am.
Sheldon: Thank you.
Dr. John Sturgis: Although, I have been called an odd duck and, one time, a quirky turkey.
Sheldon: Those people were probably jealous.

Meemaw: How much did Dale pay you?
George Jr.: Uh, minimum wage plus five percent commission.
Meemaw: I'll give you half of that.
George Jr.: So, two and a half percent commission?
Meemaw: No, half of the minimum wage part.
George Jr.: What about a percentage of these?
Meemaw: [laughs] Yeah, right.
George Jr.: I'm serious. If it wasn't for me, none of this would be happening.
Meemaw: I'm your grandmother. If it weren't for me, you wouldn't be happening.

Meemaw: I'll tell you what, we're in the gambling business, why don't we gamble for it?
George Jr.: Okay.
Meemaw: Great. The number I'm thinking of in my head... is it odd or even?
George Jr.: How dumb do you think I am?
Meemaw: In my defense, you used to be dumber.
