Missy: Hey.
Mary: Hey, baby, where's Sheldon?
Missy: I don't know, he left.
Mary: He left? Where'd he go?
Missy: He wouldn't tell me, but he wrote it in this weird letter.
Mary: When did he leave?
Missy: An hour ago.
Mary: An hour?!
Missy: I told him not to go.

Sheldon: While Dad's gone, I'm the man of the house, and the man of the house has to enforce the rules.
Missy: The man of the house is about to get his teeth knocked out.
Sheldon: Puberty's made you mean.
Missy: I need to know what happened on my show.
Sheldon: And you'll find out when your privileges are restored.
Missy: I can't wait that long, each episode builds on the last. Imagine a Star Trek that ends with "to be continued," and you don't get to continue.
Sheldon: That would never happen, because I follow the rules.
Missy: You are this close to a purple nurple.
Sheldon: [covers nipples] You leave my nurples alone.

Brenda Sparks: You friends with this girl?
Missy: [scoffs] I wish. She is so popular. One time she said she liked my outfit... I wore it for a week.
Brenda Sparks: [scoffs] What am I gonna do? [both sigh]
Missy: You could tell Billy he's too young to date.
Brenda Sparks: [chuckles softly] That's good. You might be the coolest person in this house.
Missy: Low bar, but thanks.

Sheldon: Why would New Mutants be next to New Teen Titans?
Missy: Because they both start with "New"?
Sheldon: But one's Marvel and the other's DC. Would you put Aquaman and Sub-Mariner next to each other?
Missy: I don't know, they could talk about fish.

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.

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.

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.
