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.

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: Hello, my little vicuña.
Meemaw: [chuckles] Well, hello to you, too. And more importantly, what is a vicuña?
Dr. John Sturgis: Only what I feel is the cutest camelid on the planet.
Meemaw: Well, I suppose I could ask you what a camelid is, but you're just gonna say more words that I don't know.

Meemaw: John?
Dr. John Sturgis: Hello.
Meemaw: What- What're you doing?
Dr. John Sturgis: I was doing tai chi and then I realized that I was continually being bombarded by subatomic particles and it behooves me, perhaps, to pay slightly closer attention to them. Maybe "chi" is the ancient Chinese word for the subatomic universe.
Meemaw: You're scaring me, John.
Dr. John Sturgis: Well, there's nothing to be scared of. Tomorrow, somebody will win the Nobel Prize about these particles not me. But I'm experiencing them firsthand [LAUGHS] which could be better.
Meemaw: Why don't you come down and experience them on the floor?
Dr. John Sturgis: I think I just felt a neutrino. [LAUGHING] You know, neutrinos are interesting. They never bond with anything, they're always alone. I think that one went right through my pants.
Meemaw: All right, why don't we go downstairs, and I'll fix us both a nice cup of hot tea and you can tell me all about it. Please?
Dr. John Sturgis: Okay. It was my dream to win the Nobel, and I'm not going to. I bet Sheldon will.
Meemaw: That'll be something.
Dr. John Sturgis: Yeah.

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

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.

Pastor Rob: I'm thinking it might be a good idea if we gave the kids a talk about the facts of life.
Pastor Jeff: You mean like, S-E-X?
Peg: Who are you spelling that for?
Pastor Jeff: G-O-D.
