Missy: Let's just get out of here.
Sheldon: Good. Everyone behind the counter has an earring where an earring does not belong.

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.

Paige: You're being weird, and not in the usual way. Guess that's my life now.
Sheldon: What do you mean?
Paige: Everyone is acting weird. My mom is going on dates and my dad is acting like a child. My sister's crying all the time. I just wish that everything could go back to the way it was. I don't think it will.
Adult Sheldon: It turned out I was really good at listening. The trick is to sit there, and when you want to leave, don't.
Paige: I have to live in two separate houses. And my grandma says the meanest things about my dad. I know that everyone is upset that I'm not doing well in school. It's just hard to care. Everything that used to seem important to me just doesn't anymore. So I guess, really, I just feel alone.
Sheldon: That sounds hard.
Paige: Yeah, it is.

Paige: Why are you taking a backpack to the mall?
Sheldon: This is my mall safety kit. Earplugs to drown out crowd noise, Wet-Naps to wipe down escalator handrails, a compass, a map of the mall, and a whistle, in case I get lost or approached by a woman holding a perfume bottle.
Missy: You want to stuff him in there, right?
Paige: No. [nods]

Paige: Let's go to the mall.
Sheldon: Mom doesn't like the mall.
Missy: She says the mannequins don't have enough clothes on, but I think it's 'cause we're poor.
Sheldon: We are poor. I do our taxes.
