Mary: Baby, you need to eat something.
Sheldon: But it looks like I can change the definitions of electric and magnetic fields and rotate the magnetic charge away mathematically to zero.
Mary: Maybe some fried okra would help.
Sheldon: Richard Feynman didn't develop quantum electrodynamics by filling up on fried okra.
Mary: Well, maybe that's because his mama didn't love him as much as I love you.
Adult Sheldon: Richard Feynman was Jewish. His mother didn't give him fried okra.

Adult Sheldon: I didn't realize until years later that my father was only asking questions about lightning and thunder to cheer me up. In fact, he would often pretend to be dumb just to make me feel better.

Adult Sheldon: My father didn't always get the credit he deserved. The advice he gave me actually worked out pretty well. Of course, I never told him.
George: Talked to Billy.
Missy: Why would you do that?
George: No, it was good.
Missy: Stay out of my life.
Adult Sheldon: He may not have been the world's greatest dad. But maybe we weren't the world's greatest kids.

Adult Sheldon: Ignoring things that irritate me isn't my strong suit. Obsessively fixating on them, now that's what gets me out of bed in the morning.

Meemaw: You just need a new hobby.
Sheldon: Very well. What are yours?
Meemaw: Smoking, drinking and gambling. But we can find you something almost as fun.

Adult Sheldon: Having found no answers, I took it upon myself to rectify the inconsistent timeline in Lord of the Rings. J.R.R. Tolkien had a brilliant mind, but let's be honest. He was no S.L. Cooper.

Meemaw: So, what's new?
Mary: I'm worried about Sheldon.
Meemaw: I said "new."
