Dr. John Sturgis: [on answer machine] Hello, Coopers. Dr. Sturgis here. This is a message for Mary. I have some news I need to share with you before Sheldon starts college. Please call me back. [answering machine beeps]
Sheldon: I wonder why he'd want to talk to you and not me.
Dr. John Sturgis: [answering machine beeps] Dr. Sturgis again. If Sheldon happened to hear that last message and is wondering why I'd want to speak to his mother first and not him... Excellent question! It's that kind of curiosity that makes him a true man of science. [answering machine clicks, beeps]
Sheldon: I'm a true man of science.

Meemaw: Hello?
Dr. John Sturgis: Did you know that word "hello" wasn't used as a greeting - until the invention of the telephone?
Meemaw: Hi, John.
Dr. John Sturgis: To end a phone call, it was suggested to say, "That is all."
Meemaw: Is that all, John?
Dr. John Sturgis: No, I wanted to invite you to dinner tomorrow night.
Meemaw: Great. Where we going?
Dr. John Sturgis: I can't tell you that. It's a surprise.
Meemaw: You want to give me a clue so I'll know how to dress?
Dr. John Sturgis: Well, dress as if you were going to a Mexican restaurant.
Meemaw: Oh, we're going to Puerta Roja.
Dr. John Sturgis: I can't tell you that, it would ruin the surprise.
Meemaw: John, you do realize that I'll be the one driving us there.
Dr. John Sturgis: Fine, we're going to Puerta Roja, but everything else is a surprise. That is all!

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: 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.

Billy Sparks: Who's Melissa?
Missy: Me.
Billy Sparks: Then who's Missy?
Missy: "Missy" is short for "Melissa." Like how "Billy" is short for "William."
Billy Sparks: I don't understand.
Missy: You know how your real name is William?
Billy Sparks: I'm Billy.
Sheldon: No, we call you Billy, but your real name is William.
Billy Sparks: But my underpants say "Billy" in them. Mom, is my name William?
Brenda Sparks: [sighs] Yeah.
Billy Sparks: Then whose underpants am I wearing?

Sheldon: I may not look it, but I'm the future of physics, so just move on.

Pastor Jeff: Two months! Two months till this baby comes! There's so much I thought I was gonna do in my life.
George Sr.: I'm sure you've done plenty.
Pastor Jeff: Nothing cool. Look at you. You played football and rode a motorcycle.
George Sr.: Well, you save people's souls. That's neat, right?
Pastor Jeff: Oh, it's neat as neat can be, but you know that's not what I'm talking about.
George Sr.: [sighs] Look, being a dad doesn't mean your life is over. It just means it's different. Instead of playing football, I get to coach it now. I mean, high school football. Not college like I'd hoped. I-Instead of a motorcycle, I drive a truck. To work every single day. To pay the bills. [sighs] Oh. Endless bills. What happened to my life?
Pastor Jeff: Orange wedge?
