Sheldon: Hello. Cooper residence. Sheldon speaking.
Mary: Hey, Shelly.
Sheldon: Oh, hello, Mom. How's your day going? [silence] Shelly? Shelly? You there?
Sheldon: Yes, I'm here. [to Missy] She wants to know how my day's going.
Missy: Say it's going good.
Sheldon: I can't say that.
Missy: Why not?
Sheldon: It's bad grammar.
Missy: How are you supposed to say it?
Sheldon: "It's going well."
Mary: Oh, that's nice. I've got to get back to work, but I love you and miss you very much.
Sheldon: Okay. [hangs up] I handled that really well.

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.: Thanks for waking me up.
Mary: I woke you up 40 minutes ago.
George Jr.: Well, you didn't do a very good job.

Mary: Well, I am happy to report that my potato salad is once again the hit of the potluck.
George Sr.: That's great, honey.
Mary: I feel bad for Pam Staples. No one's touching her potato salad.
Sheldon: If you feel bad, then why are you smiling?
Meemaw: 'Cause sometimes your mommy's a big ol' hypocrite.

Mary: How are you liking Medford, Selena?
Pastor Jeff: ¿Cómo te gusta Medford?
Selena: Nunca he estado tan aburrido en toda mi vida. [I've never been so bored in my entire life.]
Pastor Jeff: She likes it fine.
Mary: Oh.
Selena: Voy a fumar en el baño. [I'm going to go smoke in the bathroom.]
Pastor Jeff: She needs to use the little girls' room. Mary, could I talk to you for a second?
Mary: Sure.
Pastor Jeff: Don't worry. I'll bring her right back.
George Sr.: Wasn't worried, but okay.
Sheldon: His Spanish is terrible. That's not what she said at all.
