Meemaw: The man has a doctorate in science, and he's filling people's grocery bags.
Mary: He actually did a really nice job. He put the heavy things on the bottom. He kept the cold things together.
Meemaw: Mary.
Mary: Well, they don't always do that.

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.

Sheldon: And then they laughed at me for not knowing something that they knew. Who does that?
Mary: You do.
Sheldon: Well, this is no time for a teachable moment. Your child is hurting.
Mary: Sorry. [taps Sheldon's shoulder] There, there.
Sheldon: I guess that'll do. Now, how about a hot beverage?

Adult Sheldon: [v.o.] We often regret the things we don't say. There's a lot of things I wish I had said to my dad while he was around. That I appreciated him. That I loved him. Which is why I'm grateful for the times I did tell him how I felt.
Sheldon: Tonight was fun.
George: Yeah? Why is that?
Sheldon: Dr. Sturgis was here. Everybody talked about science. It was nice.
George: It was.

President Hagemeyer: Sheldon, Dr. Sturgis quit right before the semester started. He left me in the lurch.
Sheldon: And this is your chance to be the bigger person.
President Hagemeyer: I don't want to be the bigger person. I'll be the small, petty person. That's way more fun.
Sheldon: Please? It would make me really happy if he came back. And you said yourself my happiness is important to the university.
President Hagemeyer: Are you trying to manipulate me?
Sheldon: Hey, being small and petty is fun.

Dr. John Sturgis: Well, it's so wonderful to see you all. Thank you for having me.
Sheldon: It's great to see you, too.
Dr. John Sturgis: And, Mary, I believe I recognize these tater tots from when I packed them in your bag.
Missy: [to Mary] You're killing me.
