Mary: I figure you don't want me to walk you in?
Missy: I've trained you well.
Mary: Do you have everything you need? Lunch money?
Missy: Yep.
Mary: Locker combination?
Missy: [pulls down sock] Right here.
Mary: Why is it there?
Missy: Writing on my hand is so fifth grade.
Mary: Of course.
Missy: Okay, I'm gonna go in.
Mary: I assume you don't want a hug?
Missy: Make it quick. [they hug] That's enough.
Mary: Okay.
Missy: Wish me luck.
Mary: Good luck.

Missy: So, this Dr. Lee is turning your friends against you?
Sheldon: Essentially.
Missy: Classic move. Most girls you find crying in the school bathroom, that was it.
Sheldon: What do I do?
Missy: Well, you're in a tough spot 'cause your personality is ugh.
Sheldon: There's enough people being mean to me right now.
Missy: Sorry.
Sheldon: Can you help me or not?
Missy: It's you against a bunch of college professors. I don't think you can win this one. [Sheldon starts to walk away] Oh. Do any of them have pimples?
Sheldon: No.
Missy: Too bad, I've done a lot of damage with "pizza face."

George Sr.: What are you doing?
Missy: Watching Sheldon struggle with homework. It's so great.

Mary: Bless us, Lord, for the food we are about to receive and bless the hands that prepared it.
Missy: And bless Mom.
Mary: Thank you. Amen.
Missy: Amen.
George Jr.: Amen.
Sheldon: She's the hands that prepared it. Your blessing is redundant.
Mary: Let's eat.

Professor Ericson: So we learned that the theory of knowledge poses some very serious problems.
Sheldon: [enters] Excuse me, Professor Ericson. I've done a little reading since last we spoke, and I'm prepared to show you that everything we know about science is true.
Professor Ericson: Well, I am all ears.
Sheldon: You said I couldn't truly know anything, but there is one thing that I do know. If I question, I must think; If I think, I must exist. Cogito, ergo sum: I think, therefore I am.
Professor Ericson: You're right.
Sheldon: You're darn right I'm right.
Professor Ericson: Guys, g-give it up for Sheldon. [applause] Now for a job well done... here is a flower full of sweet nectar.
Sheldon: Why would I want that?
Professor Ericson: Because you're a butterfly and this is just your dream.
Sheldon: I'm not a butterfly.
Professor Ericson: Are you sure? [laughs]
[Sheldon wakes up:]
Sheldon: It was a dream. Oh, no. [camera pans out] Help! I'm a butterfly! Nothing I know is real! Everything is a dream! Missy, help! [Missy holds a fly swatter] No!
[Sheldon wakes up:]
Sheldon: Missy, am I awake or is this a dream?
Missy: Shut up, dingus.
Sheldon: Okay, I'm awake.

Sheldon: I stopped at the library today and picked up books on epistemology, Descartes's dream argument and the foundations of scientific logic. Do you know what she's going to do?
Meemaw: Rue the day?
Sheldon: The day, the night. If it's rue-able, she's going to rue it.

Mary: Hey, Brenda.
Brenda Sparks: She didn't want you to walk her in?
Mary: No. How about Billy?
Brenda Sparks: Oh, I walked him in. Found his homeroom. Explained that "homeroom" is different than his room at home. Still not sure he gets it.
Mary: Tough day.
Brenda Sparks: Yeah.
Mary: You want to get some coffee?
Brenda Sparks: I was thinking vodka, but coffee will do.
