Assistant Coach Wilkins: You worried your kid just invited the whole school to your house?
George Sr.: At 5:00 in the morning for a Swedish science thing? [CHUCKLES] Not at all.

George Sr.: And Sheldon's fine. You know what he's like. If someone took him, I'm sure they'll bring him right back.

Sheldon: Dad, do you believe that fossils are millions of years old?
George Sr.: I guess. Why?
Sheldon: Well, Mom believes the world was only created 6,000 years ago.
George Sr.: Yeah. So?
Sheldon: Are these differences a sticking point in your marriage?
George Sr.: Not at all.
Sheldon: Why?
George Sr.: Simple. We never talk about it.
Sheldon: So you just avoid discussing topics you don't agree on?
George Sr.: At all costs.

Meemaw: I bowled a new high score last night.
George Sr.: Nice.
Meemaw: I got two turkeys.
Missy: What's a turkey?
Meemaw: It's three strikes in a row.
Missy: Why do they call it a turkey?
Meemaw: Well, when they first invented bowling, they used to just throw frozen turkeys at the pins. Eventually, they switched to balls to cut down on the smell.
George Sr.: Why you lying to her?
Meemaw: I find it keeps my mind sharp.

Adult Sheldon: A primary feature of quarks is that they're always bonded together, but in that moment, I felt like a neutrino, destined to be alone forever.
[Montage of young Leonard, Penny, Raj, Howard, Bernadette and Amy at that moment]
Adult Sheldon: Thankfully, I was wrong.

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.

George Jr.: A bill? Really?
George Sr.: Room and board, buddy.
George Jr.: $50 a month for food?
George Sr.: The way you eat, I should've gone $50 a week.
George Jr.: Laundry services?
George Sr.: Your poor mother has to touch your underwear.
George Jr.: What's the $10 a month "peema" charge?
George Sr.: Oh, P-I-M-A, that's a "Pain in My Ass" tax. My way of getting compensated for you taking years off my life.
