Missy: [groans] Mom and Dad are still really upset.
Sheldon: With good reason. She's awfully old to be having a baby.
Missy: Is it really dangerous?
Sheldon: Not with modern science, but back in pioneer times, we'd be burying her down by the crick.
Missy: I'm just saying they're cranky enough, so don't be a pain in the ass.
Sheldon: I'm always on my best behavior. You're the hormonal firecracker around here.
Missy: Sheldon.
Sheldon: And thar she blows. Moby Dick. It's a book.

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.

Sheldon: I smell ammonia. They must've done a thorough cleaning recently. I like that.

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]

George: Where the hell's my travel mug?
Mary: I think Georgie took it, dear.
George: That son of a gun.
Mary: Missy, your father's gonna take you to school today.
Missy: Thanks, Daddy. I hope it's not too much trouble.
George: [smiles] No trouble at all, my little angel. [Mary smiles at Missy, too]
Sheldon: [to Missy] Why'd you say they're cranky? They're fine.

Mary: [chuckles] Well, at this point, it doesn't matter, because she doesn't want to get married.
Pastor Rob: Well, I can talk to her if you want.
Mary: Mm.
Pastor Rob: I'm pretty good with young people.
Mary: She's 29.
Pastor Rob: Also pretty good with people my own age. [Mary chuckles]

Pastor Rob: Knock, knock.
Mary: Oh, hi.
Pastor Rob: Just thought I'd show you how to do it on the first try. [Mary chuckles softly] You all right?
Mary: Um... Yeah. Just, you know, life.
Pastor Rob: Mm. I've heard that can be rough.
Mary: Mm.
Pastor Rob: Well, if you ever want to talk or... grab a smoke, I'm around.
Mary: I'm good, thanks. [chuckles] Although, um... A cigarette doesn't sound bad.
Pastor Rob: I was hoping someone would help me get to the end of this pack.
Mary: Then we're quitting.
Pastor Rob: Absolutely.
Mary: It's a disgusting habit.
Pastor Rob: Filthy.
