Mary: [on the phone] Dr. Linkletter, what can I do for you?
Dr. Linkletter: Hello, Mrs. Cooper. I just wanted to let you know, with Dr. Sturgis away, I'll be available should Sheldon need anything.
Mary: Oh, that is very comforting to know. Thank you so much.
Dr. Linkletter: His well-being is important to me, as was made abundantly clear by my boss.
Mary: Okay, well, we are truly grateful.
Dr. Linkletter: Now, I'm not terribly experienced around children. If he needs to use the restroom, I don't have to go in with him, do I?

President Hagemeyer: Okay, so, what's the problem?
Sheldon: I wanted to talk with Dr. Linkletter about puberty.
Dr. Linkletter: And I wanted to avoid litigation.

Dr. Linkletter: [on answer phone] Connie, Grant Linkletter. Wonderful seeing you tonight.
Meemaw: Yeah, yeah.
Dr. Linkletter: Hope you enjoyed our little book club. If you'd ever like to discuss it further, I know the perfect Italian café. The cannolis are resplendent.
Meemaw: Resplendent! [chuckles] [machine beeps]
Dr. John Sturgis: [on answer phone] Connie! John Sturgis here.
Meemaw: What a surprise.
Dr. John Sturgis: It was so nice to have you at our book club. When it comes to science fiction, those things can be real sausage parties. Anyhoo, if you're free next week, I was wondering if you'd like to... [Meemaw skips to the next message]
Dr. Linkletter: Grant Linkletter again. If you don't like Italian, I also know a sublime Vietnamese spot. Have you ever tried Bún Boò Hue? [machine beeps]
Dr. John Sturgis: I don't know why I said "sausage party." There was probably a better way to phrase that. [machine beeps]
Dr. Linkletter: Connie, Grant Linkletter...

Sheldon: Can we get back to the book?
Dr. John Sturgis: Yes, Connie, I'd love to hear more of your thoughts on it.
Meemaw: I think I've said my piece.
Sheldon: I have some thoughts.
Dr. Linkletter: And we'll get to those in due time. Don't you think Asimov did a remarkable job of capturing the poetic terror of the coming darkness?
Meemaw: I'm not sure I got that.
Dr. Linkletter: Oh, listen to this. "Dusk, like a palpable entity, entered the room, and the dancing circle of yellow lights about the torches etched itself into ever-sharper distinction against the gathering grayness beyond." [Meemaw and John are silent]
Sheldon: Powerful.
Dr. Linkletter: Wasn't it?
[Meemaw shrugs her shoulders]

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.
