[on the "Why Sheldon Cooper Should Go to College" tape:]
Dr. John Sturgis: Hi, Mary. I know this must be a hard decision for you. I can't tell you how to parent your child. I don't have children. But... I can tell you... that in all my years in academia, I've never seen a mind like Sheldon's. He's truly extraordinary. And if you let him come here, I promise we'll take good care of him.

Meemaw: Hello?
Dr. John Sturgis: Did you know that word "hello" wasn't used as a greeting - until the invention of the telephone?
Meemaw: Hi, John.
Dr. John Sturgis: To end a phone call, it was suggested to say, "That is all."
Meemaw: Is that all, John?
Dr. John Sturgis: No, I wanted to invite you to dinner tomorrow night.
Meemaw: Great. Where we going?
Dr. John Sturgis: I can't tell you that. It's a surprise.
Meemaw: You want to give me a clue so I'll know how to dress?
Dr. John Sturgis: Well, dress as if you were going to a Mexican restaurant.
Meemaw: Oh, we're going to Puerta Roja.
Dr. John Sturgis: I can't tell you that, it would ruin the surprise.
Meemaw: John, you do realize that I'll be the one driving us there.
Dr. John Sturgis: Fine, we're going to Puerta Roja, but everything else is a surprise. That is all!

Dr. John Sturgis: See, this is why we're great together. You teach me about social etiquette, and I teach you about beaver anuses.
Meemaw: [CHUCKLES] It is magical.
Dr. John Sturgis: Did you know "ani" is also acceptable as the plural of "anus"?
Meemaw: And the magic continues.

Dr. John Sturgis: Did you know that there's a type of vanilla flavoring derived from the anal glands of the North American beaver?
Meemaw: That seems like a fact you could have shared before we started eating.
Dr. John Sturgis: It isn't used very often. I understand it's difficult to, uh, milk the little sacs.
Meemaw: Cool. Okay, new topic.

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.

Ms. Ingram: Honestly... teaching Sheldon is the hardest thing I've ever had to do. And I don't say that because he can be a pain. I say that because he's so intelligent, I had to study every night just to keep up. I'm gonna miss him.
