Sheldon: And how does the pope work?
Tam: Well, the pope lives in Italy. He has a special car, and a big pointy hat. It's a wonderful hat.
Sheldon: And is there anything else I should know about?
Tam: Every once in a while, you have to confess your sins to a priest.
Sheldon: Not me, I don't have any sins.
Tam: Then you have the sin of pride.
Sheldon: Your religion is making me feel bad.
Tam: That's how you know it's working.

Mary: You smoke marijuana?
Sheldon: Mom!
Libby: No, ma'am.
Tam: Just say no. [Mary shoots him an unimpressed look]

Tam: Look at this, my mother left me a note. "You can do better. Mom." Not "Love, Mom," not "XO, Mom," just "Mom."

Tam: Spending the Thanksgiving weekend working in my family's convenience store, I observed my father and mother working from 6:00 in the morning till 10:00 at night. My hypothesis was that economic advancement for immigrant families is more important than celebrating a holiday where people eat until they pass out in front of the TV.
Mr. Givens: All right, Tam. Well, based on your observations and hypothesis, were you able to make a prediction?
Tam: Yes. At some point, my father would die prematurely from stress. And my mother will come live with me, where she will constantly disapprove of my hot, blonde, American wife.
Mr. Givens: Okay. Uh, I think we all learned something there. Uh, thank you, Tam.

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.
