Mary: Shelly, I understand you enjoy researching things.
Sheldon: Love it.
Mary: But it's important to keep in mind that there is only one true God.
Sheldon: That's called monotheism. I have a book about it if you're interested.
Mary: That's okay, I have the book about it.
Sheldon: Would you be angry with me if I don't pick your religion?
Mary: I could never be angry with you. You be a seeker of your own truth.
Sheldon: Thanks, Mom.
Mary: And if the truth turns out to be Satan, I will do battle with him.

Pastor Jeff: And now George's loving wife Mary would like to say a few words. Mary.
Mary: Thank you, Pastor Jeff. Um... [clears throat] I met George in high school. Well, I was in high school. He was an older man with a motorcycle. [light laughter] I'd like to tell you he caught my eye, but actually it was the motorcycle. [laughter] [voice breaking] I'm sorry, I can't... do this. I am... so angry. [sighs] George and I had our ups and downs, but we were finally in such a good place, and then he... left. [crying] He left all of us. I- How could you do that? [Meemaw stands up] I am so mad at him. I'm mad at God, I'm mad at myself for not trying harder while he was here. [Meemaw goes up to Mary] This wasn't supposed to happen. [Mary sobs] [Meemaw hugs Mary] [Georgie hugs a crying Missy]

Sheldon: Mom, when should I be expecting my testicles?
Woman: [turns around] What is wrong with him?
Mary: Nothing is wrong with him. Now turn around before I knock your lights out.
Sheldon: Hello.

Sheldon: Regardless, I'm not interested in making any more friends.
Mary: Oh, I don't think that's how you really feel.
Sheldon: It is. From now on, it's a hermit's life for me.
Mary: I bet, when you grow up, you will be surrounded by lots of smart, wonderful friends.
Sheldon: I can't see that happening.

Pastor Jeff: Come on up here, Sheldon. Let's hear what you got.
Sheldon: I've spent the last week studying what people believe, and I've come to a conclusion.
Pastor Jeff: And what's that?
Sheldon: I'm starting my own religion.
Pastor Jeff: I'm sorry, what?
Sheldon: I'm calling it Mathology. It's based on a universal binary system.
Pastor Jeff: That's terrific, Sheldon, but this is a Baptist Sunday school.
Sheldon: I know, I'm here to convert everybody. Any takers?
Pastor Jeff: Okay. Let's go have a talk with your mom.
Sheldon: The only sin in Mathology is being stupid.

Pastor Jeff: Okay, "What God means to me." Who'd like to go first? Billy.
Billy Sparks: I'd like to go third.
Pastor Jeff: All righty.

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.
