Dr. John Sturgis: [on the phone] So how can I help?
Sheldon: I posted a theory on the collapse of wave function. We've been arguing back and forth and he's saying that my probabilities come out negative.
Dr. John Sturgis: Hmm. I see. Have you considered that negative probabilities can still have meaning?
Sheldon: Ooh, I hadn't. That suggests another idea. I can argue that negative probabilities only show up in intermediate steps. I'm gonna destroy him with this.
Dr. John Sturgis: And when you do, feel free to call him a Scarabaeus viettei, a dung beetle.
Sheldon: Oh, I so admire your mind.
Dr. John Sturgis: Back at you, little man.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

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.

Adult Sheldon: Thanks to Dr. Sturgis, I had all the intellectual ammunition I needed to bring my opponent to his knees. I accused him of conflating two different interpretations of quantum theory, woefully misrepresenting Paul Dirac, and when I called him a dung beetle in Latin, I was so riled up, I almost started producing testosterone.

George: So how'd you wind up coaching baseball?
Dale: Well, with the sporting goods store, you know, I've sponsored a couple of teams, and then this year, my grandson wanted to play, so it lets me spend more time with him.
George: That's nice. Yeah, I coach my son in football.
Dale: Sheldon?
George: Oh, God, no. Can you imagine?
Dale: You really scared me there for a second.

George: Oh, yeah. Connie's great. You can have a beer with her, watch a football game, joke around. She doesn't mind if you swear. In fact, that woman's got a mouth on her.
Dale: I have noticed that.
George: Yeah. You know, I just realized something. I got more in common with my mother-in-law than I do my own wife.
Dale: That's kind of creepy.
George: Yeah. Let's hope the beer does its job and I don't remember this tomorrow.
