Missy: And then Heather B said she didn't want to play tetherball with Heather M anymore.
George: Wait. Th-There's two Heathers?
Missy: Oh, yeah.
George: Which one's which?
Missy: Heather B is stuck up. Heather M used to be stuck up, but then she got a scoliosis brace.
George: Maybe she shouldn't be playing tetherball.
Missy: That's what Heather B said.

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.

Meemaw: This is delicious, but you were not kidding about the spice. I'm about to break a sweat here.
Dr. John Sturgis: Well, here's something you might find interesting. Spicy food is typically found in warmer climates because it induces sweating, which in turn, cools people off.
Meemaw: So what does the runny nose do for me?
Dr. John Sturgis: It allows me to, uh, gallantly offer you my handkerchief.
Meemaw: You are such a gentleman.
Dr. John Sturgis: When I was younger, I read a book on etiquette. That's how I know that if I ever have an audience at the Vatican, I should wear evening attire or a sack coat.
Meemaw: I don't know what a sack coat is, but I'm sure you'd look handsome in it.
Dr. John Sturgis: Thank you.

George: So, Dr. Sturgis, Sheldon tells us you're a guest professor at the university.
Dr. John Sturgis: I am.
Mary: Hmm. Does that mean that you're only here temporarily?
Dr. John Sturgis: Well, that's the plan for now. But I could be enticed to stay.
Sheldon: Meemaw, I do believe there was subtext there. Did you pick up on it?
Meemaw: Yeah.
Sheldon: Was I correct to infer there was subtext there?
Dr. John Sturgis: You were.
Sheldon: Okay, we're all good.

Dr. John Sturgis: You weren't kidding. Spaghetti and hot dogs is delightful.
Sheldon: Even better since Mom perfected the chunk ratio.
