Sheldon: Why are you taking that down?
Missy: It's time to grow up.
Sheldon: Leave it there.
Missy: You don't even like Cyndi Lauper.
Sheldon: No, but it's part of my daily routine. Every morning I wake up, look over there and wonder, "Why is she standing like this?"
Missy: Too bad. It's my room.
Sheldon: It's my room, too.
Missy: Yeah, and I don't get a say in any of your stupid posters.
Sheldon: These are the smartest men who ever lived, so if anyone's stupid, it's you for saying that.
Missy: Shut up!
Sheldon: You're very irritable. This might be why you're having boy problems.

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.

Mary: You are right. You have been here longer than me. I don't see why we can't work together.
Peg: That'd be nice.
Mary: Great. So, why don't you go by the bank, and I will drop off the bulletin?
Peg: So no one's gonna answer the phones?
Mary: Fine. You just sit there, and I'll go and do everything.
Peg: Sweet. Oh, today's a stumper. Is "nipto" a word?
Mary: You know what? This is why I was taking charge of everything. Because if I don't, nothing will get done.
Peg: Oh, it's "pinto". [laughs]
Mary: This is exactly what I'm talking about.
Peg: Guess what, Mary. Things were getting done long before you got here.
Mary: I just want everything taken care of for Pastor Jeff.
Peg: Or you just like thinking you're better than everybody.

Sheldon: Where are we going?
Missy: Right there.
Sheldon: An old shack in the middle of the woods? Have you even seen Scooby Doo?
Missy: Great, go home.
Sheldon: At night, by myself? Nice try.

Pastor Jeff: Isn't he the cutest?
Mary: He sure is.
Peg: Oh.
Pastor Jeff: Yeah, he's an angel. He's just happy all the time... morning, afternoon, middle of the night, 2:00a.m., 3:00a.m., all the a.m.'s, really.
Peg: Dip the pacifier in some whiskey, put him right out. But don't use the good stuff. They can't tell the difference.
