Sheldon: I want to understand God. Can you help me?
One: Did you not hear what we just said?
Zero: It's a binary universe.
One: God is yes and no.
Zero: Left and right.
One: On and off.
Zero: Something and nothing.
One: Positive and negative.
Zero: Male and female.
One: Light and dark.
Sheldon: But why is there evil and suffering?
Zero: Well, without evil and suffering, there is no good and happiness.
Sheldon: Oh, sure. Binary.

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.

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: Let's say grace.
Sheldon: Hang on, safety first. [puts mittens on]
George Jr.: When are you gonna get over that?
Sheldon: I would think recent events would make you value protection.
Mary: Enough.

Mary: Anyway, I'm sorry to drag you into this, but it is demons, so it's in your purview.
Pastor Jeff: It is indeed. In fact, at a recent Young Baptist Leaders Conference, I attended a seminar on satanic leisure activities.
Mary: And?
Pastor Jeff: And the important lesson is, rather than have a parent or authority figure take the offending game away, let God remove it, root and stem.
Meemaw: Question, PJ. Uh, how's the big guy do that?
Pastor Jeff: Simple, Sheldon needs to start attending Sunday school. If he likes books with demons and devils, I've got one that will blow his mind.
George Sr.: What book is that?
Mary: The Bible, George.
George Sr.: Sure, yeah.

Adult Sheldon: My mother didn't believe in elves, fairies, or dragons. But she did believe in the devil. And she did not view him as an appropriate playmate for her son.

Ira Rosenbloom: So, Sheldon, you hungry? You want a nosh?
Sheldon: I don't know, I've never eaten a nosh.
Ira Rosenbloom: (chuckling) Uh, no, a nosh isn't a thing, it's a never mind. Um, would you care for some hard candy?
Sheldon: Are they kosher?
Ira Rosenbloom: Who are you, my mother?
