Sheldon: Good news. I found a way to take a break from science.
Mary: That's great. What is it?
Sheldon: A fantasy book series called The Lord of the Rings.
Mary: Well, it's got "the Lord" in it. That's something.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Mary: Sheldon Lee Cooper, if you don't finish that pork chop, I swear I will chew it up and spit it in your mouth like a mama bird.
Missy: Do it, Mom. Do it.

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.

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.

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