Sheldon: Tam, I need help navigating a social situation.
Tam: I'm eating lunch with you. You think I have the answer?
Sheldon: Dr. Linkletter invited me to a lecture on robotics, but my meemaw said he's only doing it to spend time with her.
Tam: Are you asking if men do sketchy things to get dates?
Sheldon: Yes.
Tam: Well, then, I can help you. Absolutely. Last week, I told Jessica Geiger I was an extra in Karate Kid Part II.
Sheldon: Did it work?
Tam: Again, I'm having lunch with you.

Mary: You smoke marijuana?
Sheldon: Mom!
Libby: No, ma'am.
Tam: Just say no. [Mary shoots him an unimpressed look]

Tam: Spending the Thanksgiving weekend working in my family's convenience store, I observed my father and mother working from 6:00 in the morning till 10:00 at night. My hypothesis was that economic advancement for immigrant families is more important than celebrating a holiday where people eat until they pass out in front of the TV.
Mr. Givens: All right, Tam. Well, based on your observations and hypothesis, were you able to make a prediction?
Tam: Yes. At some point, my father would die prematurely from stress. And my mother will come live with me, where she will constantly disapprove of my hot, blonde, American wife.
Mr. Givens: Okay. Uh, I think we all learned something there. Uh, thank you, Tam.

Tam: Look at this, my mother left me a note. "You can do better. Mom." Not "Love, Mom," not "XO, Mom," just "Mom."

Sheldon: State troopers. I wonder what they want.
Adult Sheldon: It turns out they wanted me. Fun fact, this was one of seven times I was brought home by law enforcement once, on the back of a horse.

Georgie: What can I say? I'm entrepreneurialistic.
Veronica: Is that a word?
Georgie: I don't know. But if you got a lot of money, you get to make stuff up.

Sheldon: That robotics lecture's going to be eye-opening. Get ready to forget everything you know about robot communication.
Meemaw: Moon Pie, I don't know if we're gonna go to this thing.
Sheldon: Why not? We've established that you're free, and I'm a child, so my schedule's wide open.
Meemaw: It's complicated.
Sheldon: Well, we're just sitting here, and we have to talk about something.
Meemaw: Can you just let this one go?
Sheldon: I think we both know the answer to that question.
