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.

Mary: Shelly and this college stuff is killing me. I... I never went to college. How can I prepare him?
Brenda Sparks: Mary, if that kid is smart enough to have colleges wanting him already, he's got to be smart enough to figure it out.
Mary: Maybe. It still hurts to hear him say he wants to leave.
Brenda Sparks: I bet. On the other hand, I'm worried my Billy will never be ready to leave.
Mary: Oh, of course he will.
Brenda Sparks: Damn. Smoking, drinking, lying. You're covering all the sins today.

Mary: So, George is mad at me, and Sheldon is mad at me, and... honestly, I'm mad at me, too.
Brenda Sparks: Will you please give yourself a break? All that you do for that family, I am surprised you didn't crack years ago.
Mary: How do you handle it all?
Brenda Sparks: I'm sitting in a chicken coop drinking a wine cooler at 11:00 a.m.... clearly, I don't.

Sheldon: Collecting! Collecting!
Brenda Sparks: Hey, Sheldon.
Sheldon: Hello, Mrs. Sparks. I'm here to collect for this week's paper delivery.
Brenda Sparks: Right. Hang on.
Sheldon: Also, I'm given to understand that tipping is customary, so feel free to express your appreciation.
Brenda Sparks: Here you go.
Sheldon: You tipped me a dime?
Brenda Sparks: Is there a problem?
Sheldon: No, it just doesn't seem like very much.
Brenda Sparks: You were late every day.
Sheldon: Well, I had to brave the elements.
Brenda Sparks: I saw you. "Brave" isn't the word that I would use. [cackles]

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.

Pastor Jeff: Dear Heavenly Father, as we return to school, we look to your eternal...
Billy Sparks: [stands] I pledge allegiance to the...
Pastor Jeff: Billy, it's not the pledge.
