[on the "Why Sheldon Cooper Should Go to College" tape:]
Principal Petersen: A student like Sheldon comes along... once in a lifetime. This school is not gonna be the same without him. But I know he's gonna do great things. And I'm honored to have been a small part of it.

Sheldon: You wanted to see me?
Principal Petersen: When don't I want to see you, Sheldon? Come in. I have something I'd like to give you. This is a key to the faculty restroom. No students allowed. One person at a time. And unlike the other restrooms, this one gets cleaned every night.
Sheldon: Thank you.
Principal Petersen: No, Sheldon. Thank you.
Sheldon: You're welcome.

Mandy: What's going on?
Coach Wilkins: Mary, we got some bad news.
Mary: Where's George?
[Missy and Meemaw wander over and stand next to Mary]
Principal Petersen: I'm so sorry. He, uh... He had a heart attack.
Missy: But he... he's okay, right?
Principal Petersen: He's gone.

George: Hey, Tom, you got a minute?
Principal Petersen: Pretty busy. Make it quick.
George: It turns out I don't need that raise.
Principal Petersen: What happened, you win the lottery?
George: No, no.
Principal Petersen: Aw, George, I am so sorry.
George: Well, what can you do?
Principal Petersen: Listen, I cleared your raise already, why don't you just keep the money.
George: Oh, no, I couldn't do that.
Principal Petersen: No. No, I mean it. It's yours.

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.

[on the "Why Sheldon Cooper Should Go to College" tape:]
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.

Missy: Interesting.
Sheldon: What does it say? No, don't tell me. Okay, tell me. No, don't!
Missy: Sheldon, if I tell you but you never look at it, then you didn't break the law, right?
[later:]
Janice: [answers phone] Law offices of Morris, Morris & Yorn. Janice speaking.
Sheldon: [on the phone] Hello. I'd like to speak to either Morris, Morris or Yorn.
Janice: May I ask what it is in regard to?
Sheldon: Well, I was slicing a hot dog...
