Mary: All right, baby, we're leaving here in a few minutes, but we'll be back on Sunday and your Meemaw will be here. [Sheldon doesn't respond] Sheldon?
Sheldon: What?
Mary: We're leaving.
Sheldon: Where are you going?
Mary: To San Antonio.
Sheldon: When are you leaving?
Mary: In a few minutes.
Sheldon: When will you get back?
Mary: Sunday.
Sheldon: But who's going to watch us?
Mary: Meemaw.
Sheldon: Okay. Bye.
Mary: Can you at least give me a hug?
Sheldon: I can.

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

Missy: What's it like to not believe in God?
Sheldon: It's great. Big fan.
Missy: Are you ever afraid you're wrong?
Sheldon: About religion? Never. About other things? Also never.

Ms. MacElroy: Now, can anyone tell me why Melville shifts the narrative voice from Ishmael to Ahab? [Ms. MacElroy waits for somebody else to raise their hand] Sheldon.
Sheldon: I have a tummyache. I'd like to see the nurse.
Derek: A "tummyache"?
Sheldon: Yes, Derek, I have a tummy and it aches. Ergo, tummyache.
Derek: Ergo?
Sheldon: It's Latin, Derek.
Ms. MacElroy: Go to the nurse.
Sheldon: And to answer your question, the shifting point of view grants the reader a broader perspective of events than typically allowed by first-person narration.
Ms. MacElroy: Where were we?
Sheldon: And "ergo" is Latin for "hence," Derek.

George Jr.: Just out of curiosity, when exactly are you and Mom leaving, and when exactly are y'all coming back?
George Sr.: You're not bringing your girlfriend here.
George Jr.: Excuse me for taking an interest in your life.
George Sr.: Besides, your grandma'll be here the whole time.
George Jr.: Never mind. Wait. So her house'll be empty?
George Sr.: Look, I used to be your age, but can you try thinking with your brain for once?
George Jr.: If you used to be my age, I think you know the answer to that.

Mary: So you've stayed at this hotel before?
George Sr.: Oh, yeah. It's nice. They got an indoor pool and a killer breakfast buffet. There's even a real nice gym we'll walk right past on the way to the breakfast buffet.

Dale: So, how does this work?
Sheldon: You start by creating your character.
Missy: I want to be a Ninja Turtle Princess of Power.
Meemaw: Put me down for that, too.
Sheldon: You have to choose from one of the character classes. There's thief, druid, paladin, wizard...
Missy: Ooh, wizard. I want that.
Sheldon: All right.
Missy: Then I'll use my magic to turn me into a Ninja Turtle Princess of Power.
Sheldon: No.
