Sheldon: What is happening to our family?
Missy: I know. Georgie and Meemaw in jail.
Sheldon: Mom getting kicked out of the church.
Missy: Georgie having a baby out of wedlock. You know what this means, don't you?
Sheldon: What?
Missy: We really are white trash.
Sheldon: Speak for yourself. I'm in college on a full ride. But I wish y'all luck.

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]

Sheldon: Missy and I broke a lot of rules the other night, and we've received no punishment.
George Sr.: [sighs] Buddy, it's been a rough week. We're just glad you're both safe.
Sheldon: But in the absence of a divine being, society's rules are what keeps a person's morality in check.
George Sr.: Well, there you go.
Sheldon: No, y-you're not following me. If actions have no repercussions, society breaks down, everything devolves into chaos.
George Sr.: You might be overthinking this.
Sheldon: I thought so, too. Then I thought about it, and I'm not.
George Sr.: Sheldon, you had one bad night. Just let it go.
Sheldon: But... I did something wrong and I got away with it. That's not okay.
George Sr.: Buddy...
Sheldon: Socrates maintained that the man who lies to himself has an enemy living within. He's not even a person. He's just a chaos of selfish desires wrapped in an animal hide.

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.

Mary: All right, what do you know?
George Sr.: Well, they're probably gonna have to pay some fine, and-and they're gonna need cash.
Mary: My son is gonna be in jail overnight?
George Sr.: What about your mother?
Mary: Oh, she's been there before.

Sheldon: Meemaw's in jail?
Mary: Uh... No.
George Sr.: Forget about it.
Sheldon: Forget about it? Do I need to remind you I remember my birth?
George Sr.: [grunts] Go to your room.
Sheldon: That was a rough day.
Mary: Rough day for me.

George Sr.: I really appreciate this, Dale.
Dale: Smuggling cigarettes? What the hell was she thinking?
George Sr.: It was Georgie's idea.
Dale: Well, that makes more sense. Well, whose truck we taking?
George Sr.: You're coming?
Dale: My ex-girlfriend in jail at the Mexican border? [chuckles] I got to take pictures.
George Sr.: [scoffs] All right, I'll drive.
Dale: But we got to stop and get film.
