Sheldon: Why do people cry at weddings?
Mary Cooper: They're practicing for what's coming later.

Mary Cooper: All right, everyone, calm down. Let's all remember what it says in the Bible: "He who is slow to anger is better than the mighty."
Beverly Hofstadter: Oh, dear woman, can you please read another book?
Mary Cooper: When God writes one, I will.

Alfred Hofstadter: So, after your husband passed, you never remarried?
Mary Cooper: No, just focused on work and the church.
Alfred Hofstadter: Ah. And what do you do?
Mary Cooper: I work at the church.

Alfred Hofstadter: Well, on that note, there are many cultures that have an apocalyptic flood as part of their mythology.
Mary Cooper: I don't have a mythology. I have the unerring Word of God. But that's very interesting.
Alfred Hofstadter: Oh. I, I didn't mean to disparage your faith. Actually, I admire it.
Mary Cooper: Really?
Alfred Hofstadter: Yes. Yes, I'm an agnostic myself. But I have prayed many times to God, to turn my wife into a pillar of salt.
Mary Cooper: Well, He came close. Turned her into a giant block of ice.

Mary Cooper: I've always had a special place in my heart for Leonard. Taking care of my baby all these years.
Sheldon: Excuse me, I take care of him.
Mary Cooper: Sure you do.

Mary Cooper: So who else is coming to this shindig?
Amy: Oh, well, the usual gang. Penny's family is coming tomorrow.
Sheldon: Yeah, and Leonards mother's already here.
Mary Cooper: Oh. Beverly. How nice.
Amy: You've met her, right?
Mary Cooper: Yes, I have. (reveals her cross necklace)
Sheldon: Mother, she's an atheist, not a vampire.
Mary Cooper: Either way, let's stop and get some garlic.

Mary Cooper: Well, honey, don't send it back yet. Your sister's married, and I'm not letting your brother give my grandmother's ring to that whore he's dating.

Sheldon: Wasn't Mary Magdalene a woman of ill repute?
Mary Cooper: When your idiot brother redeems mankind, he can date whoever he wants.

Mary Cooper: Do you wanna tell me what happened?
Sheldon: Are you gonna say it's all part of God's plan?
Mary Cooper: Good chance.

Mary Cooper: I'm so glad that you and I were able to bury the hatchet.
Beverly Hofstadter: Me, too. And I respect your right to your beliefs.
Mary Cooper: And I will pray for you.

Mary Cooper: When your mom gets back, I'm gonna need to apologize for the way I spoke to her.
Penny: Well, come on, she did kinda start it.
Mary Cooper: Doesn't matter. A good Christian would have turned the other cheek. On the other hand, a good Texan would have shot her, so I'll just split the difference.

Leonard: Not once did my mother ever give me any love or affection for just being myself. I always had to earn it.
Mary Cooper: Oh, Leonard, I'm sure she loves you very much. In her own cold godless way.

Mary Cooper: At least the bearded man I believe in preaches love and compassion. All yours talks about is why you hold in your poop and want to crawl back inside your mama.

Mary Cooper: I know the answer. You're not gonna like it.
Beverly Hofstadter: Try me.
Mary Cooper: When I was pregnant with Shelly, I was driving to church. And I was praying to the Lord to give me a son smarter than his dumb-ass daddy. And I looked over and I saw a Jesus bobblehead in the Subaru next to me, nodding yes.

Mary Cooper: Ugh? The bible is ugh to you?
Beverly Hofstadter: No, I'm sorry. That was inappropriate. As a psychiatrist, I know how important people's superstitions can be to them.
Mary Cooper: You want to talk about superstitions. Sheldon sent me all those books you wrote. All that nonsense about super egos and IDs. What bull dropped that on the barn floor?
