Dr. John Sturgis: Hello, Mary. This is John Sturgis, Sheldon's professor and your mother's lover.
Mary: Hi. And "John" was more than enough.

Dr. John Sturgis: I don't think I can do this, Connie.
Meemaw: Of course you can. We're just getting started.
Dr. John Sturgis: No, it's too much information. I can't process it.
Meemaw: It was just a yellow light.
Dr. John Sturgis: Not just the light. There were other cars. There's pedestrians. There was a guy on a bicycle.
Meemaw: So?
Dr. John Sturgis: That's just too many random elements. The- The- The stimuli are overwhelming.

Meemaw: I have only seen you eat vanilla ice cream for dessert. Why is that?
Dr. John Sturgis: Well, I've taken a page from the great physicist Richard Feynman. In order to have one less decision in his life, he decided that dessert would always be chocolate ice cream.
Meemaw: Sounds like it could get kind of boring.
Dr. John Sturgis: Oh, it does. But over the last 35 years, I believe I've saved at least a day and a half.

Meemaw: I'm warning you, once you try my barbecue, it will ruin you to all the others.
Dr. John Sturgis: That's what happened to me with quilted toilet paper. Once I tried the good stuff, everything else felt like a Brillo pad.
Meemaw: You paint quite the picture, don't you?

Meemaw: What are you doing?
Dr. John Sturgis: Considering buying this jacket. I found chewing tobacco and Juicy Fruit in the pocket. Does that come with it, or is it extra?
Meemaw: Actually, that's not for sale. Why don't you look for something else.
Dr. John Sturgis: You sure? There's a price tag on it.
Meemaw: Just take it off.
Dr. John Sturgis: Is this some kind of bargaining technique? Because I should warn you. I've been to the bazaars in Istanbul, where the negotiations are fast, furious and bilingual.

Meemaw: John, I don't think you realize the responsibility involved here.
Dr. John Sturgis: Well, why don't we have a trial run? Have him spend a couple days with me and see how it goes.
Meemaw: A trial run, huh?
Dr. John Sturgis: Like the space program. You don't send people up right away; you start by spinning them around in that thing that makes them throw up.

Dr. John Sturgis: What were you thinking, letting me take care of a child? I won't make that mistake again. Do I look like Mary Poppins?

Dr. John Sturgis: Excuse me! Everyone!
George: Oh, boy.
Dr. John Sturgis: I would like to propose a toast to George Cooper. I don't mind telling you I'm going through a bit of a rough patch, and this man went out of his way to take me here and listen to my woes. And George and I don't even know each other that well.
George: You heard it. Y'all heard it.
Dr. John Sturgis: But I just broke up with a woman. A beautiful, passionate woman. Adventurous. Sensual. Apparently, you're never too old for heartache. But tonight, I found solace in the bosom of male friendship. To George Cooper. [silence] Drinks are on me!
All: To George Cooper! [cheers]

Dr. John Sturgis: Hello!
Georgie: Sheldon's not home.
Dr. John Sturgis: Oh. I-I'm here to watch a sporting event with your father.
Georgie: Really?
Dr. John Sturgis: Yes. He only called it "the game," so I don't know which one it is.
Georgie: Well, this is just great. Come on in.
Dr. John Sturgis: Thank you.
Georgie: Hey, Dad, Dr. Sturgis is here to watch football with you.
Dr. John Sturgis: Oh, football. Good, that was the one I read up on.

Dr. John Sturgis: [on the phone] What's on your mind?
Sheldon: Do you ever wish that you weren't smart?
Dr. John Sturgis: So I would be short, lonely and stupid? No, that seems worse.

Dr. John Sturgis: What are you doing here?
Meemaw: Me? What are you doing here?
Dr. John Sturgis: Well, this is where I hang out now. I grade papers, I chat with the other patrons. The people who like to bet on football rub my head for luck.

June: [answering phone] Hello?
Dr. John Sturgis: Hi, June. John Sturgis here. We met the other day. I'm, uh, the scientist who won over the whole bar.
June: Oh, sure, I remember you.
Dr. John Sturgis: Good, good. Anyway, I was wondering if you had any romantic interest in me.
June: Well, you don't beat around the bush, do you?
Dr. John Sturgis: In medieval times, hunters used to hire men to beat the area around bushes with sticks in order to flush out game, so no, I guess I don't do that.

Dr. John Sturgis: I'd like to end today's lecture with a hilarious physics joke. Why didn't the photon pack a suitcase? He was traveling light. [Sheldon raises his hand] Sheldon?
Sheldon: Ha, ha.
Dr. John Sturgis: Thank you. Class dismissed.

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.

Dr. John Sturgis: [v.o.] Dear Connie, you may have heard I've taken a job at the new supercollider in Waxahachie. I wanted to tell you in person, but, uh, I was afraid you'd be upset. And, honestly... I was even more afraid you wouldn't be.
Meemaw: Oh, John.
Dr. John Sturgis: This also gives me an excuse to use my astronaut pen. I'm not upside-down, but if I was, it would still write. [laughs]
