Sheldon: I thought you were going back to Austin?
Paige: Uh, I'm not going back. I'm gonna drop out.
Sheldon: What? Where will you go?
Paige: I was thinking here, in your dorm.
Sheldon: Here?
Paige: Well, I mean, just for a couple days until I can figure out how to tell my mom.
Sheldon: I don't know.
Paige: Please? I don't have anywhere else to go, and... as embarrassing as this is to admit... you're the only person who can help me right now.
Sheldon: [sighs] Okay.
Paige: Thanks.
Sheldon: It's the least I can do. My life is going so much better than yours.

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]

Mary: Sheldon, faith means believing in something you can't know for sure is real. And right now, I am struggling with that.
Sheldon: So you don't believe in God anymore?
Mary: That isn't something for you to worry about. I need to figure this out myself.
Sheldon: Can I help? Maybe I could provide a fresh perspective.
Mary: I don't think so, baby.
Sheldon: Did you know that if gravity were slightly more powerful, the universe would collapse into a ball?
Mary: I did not.
Sheldon: Also, if gravity were slightly less powerful, the universe would fly apart and there would be no stars or planets.
Mary: Where you going with this, Sheldon?
Sheldon: It's just that gravity is precisely as strong as it needs to be. And if the ratio of the electromagnetic force to the strong force wasn't one percent, life wouldn't exist. What are the odds that would happen all by itself?
Mary: Why are you trying to convince me to believe in God? You don't believe in God.
Sheldon: I don't, but the precision of the universe at least makes it logical to conclude there's a creator.
Mary: Baby, I appreciate what you're trying to do, but logic is here. And my problem is here.
Sheldon: Well, there are 5 billion people on this planet and you're the perfect mom for me. What are the odds of that?

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: Paige? Why are you here?
Paige: The lecture.
Sheldon: Well, if you're looking to jump the line, I don't do cutsies.
Paige: No, I'm actually part of the lecture. Professor Patterson is my mentor at U.T.
Sheldon: Really? You're part of the quantum gravity team?
Paige: Yeah, it's actually really interesting. We've been examining all...
Sheldon: I know what it's about. It's why I've been waiting in line for three hours.
Paige: Wow, three hours to see me speak? I didn't know you were such a fan.

Mary: Oh, I know that you're hurting, and... I'm here for you, so... what do you need?
Meemaw: Great, take me drinking.
Mary: It is 3:30 in the afternoon.
Meemaw: Yes, it's called happy hour.
Mary: I have to make dinner.
Meemaw: Oh, fine. I'll just be sad and drunk by myself. Maybe I'll go home with the bartender.
Mary: Missy! I have to go out with your meemaw, but I'll be back later with KFC.

Missy: Meemaw picked me up in her new car.
Meemaw: We drove with the top down. A truck driver honked at us. [chuckles]
Missy: It was awesome.
Meemaw: See? Missy loves my car. I don't know what Dale's problem is.
Missy: You're too good for him anyway.
Mary: Should she really be hearing about all this?
Missy: Mom, she just got dumped. It's what you do. Ooh, is any of his stuff at your house? Let's set it on fire.
Mary: Don't you have homework?
Missy: My grandma's hurting. She needs me.
Mary: Go.
