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.

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]

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.

Mary: You understand that some people are going to be intimidated by you, because of how smart you are?
Sheldon: Or maybe they'll recognize my intellect and make me their leader.

Adult Sheldon: Sundays were not my favorite day. In fact, the only light at the end of the tunnel was the wry musings of Andy Rooney at the end of 60 Minutes.
Andy Rooney: [on TV] Noise is sound you don't want to hear. And of course, one person's sound is another person's noise.
Sheldon: So wry.
Adult Sheldon: The rest of the day was filled with football, church and the only school I didn't enjoy attending, Sunday school.

Missy: Do you believe in God?
George Jr.: Yeah.
Missy: But in the Bible, he does all kinds of mean stuff. If he's good, why would he do that?
George Jr.: Maybe he just wants to show he's in charge. Hulk Hogan's nice, but in the ring, he will mess you up.
Missy: That's either really smart or really stupid.
George Jr.: That's what I do.
Missy: Do you ever wonder if it's all made-up?
George Jr.: Look, this is Texas. We like football. We like God. And beef. Beef's up there, too.
Missy: But how do you know there's a God?
George Jr.: See that girl dancing in them shorts? There's a God.

George Sr.: [on the phone] What did you tell her?
Brenda Sparks: Nothing.
George Sr.: Well, whatever you said's got her sniffing around me like a hound dog after a polecat.
Brenda Sparks: A hound dog after a polecat?
George Sr.: When I get nervous, I get extra country.
Brenda Sparks: Did you get country in front of her?
George Sr.: No.
Brenda Sparks: So you played it cool.
George Sr.: No.
