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.

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.

Amy: What took you guys so long?
Leonard: Oh, we were following Howard, but for some reason, he turned off his headlights and went up a one-way street.

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.

Leonard: And, of course, Mom.
Alfred Hofstadter: Hello, my hateful shrew.
Beverly Hofstadter: Hello to you, you wrinkled old bastard.
Sheldon: All right, now I'm starting to sense a little tension.

Penny: So, what did we miss?
Alfred Hofstadter: Oh, just Mary and I getting to know each other a little.
Mary Cooper: Leonard, your father is just charming.
Beverly Hofstadter: He's also broke. Did he mention that?

Leonard: I'd love it if my dad could come.
Penny: Oh, you have to invite him. I haven't seen him since the divorce.
Leonard: Oh, he's like a different man. He stopped twitching, and I think he grew an inch and a half.

Leonard: How'd it go with my mother?
Penny: Uh, you know, it started a little rocky, but I think we got to a good place.
Leonard: Wow. Well done.
Penny: Yeah, and when I dropped her off at the hotel, she even gave me a hug.
Leonard: Did she think you were choking or ...?

Bernadette: Oh, stop. You know what's really happening? All the movies you've watched, the TV shows, the comic books, they've completely twisted your thinking. No one's after you, no one's listening to you, no one cares about you.
Raj: I'd like to think the Four on Your Side guy cares about me.

Alfred Hofstadter: Now, one of the more exciting things to be found recently is that Neanderthals and Homo Sapiens frequently mated with each other.
Mary Cooper: Well, that certainly explains my marriage to Sheldon's father.
Sheldon: That's funny because my father was not a very clever man.
Amy: I'd be lost without you.

Howard: I can't believe I was so naive. The military is just gonna take over the whole project. And you know what happens if we object? We disappear. Like off the map. Like every American Idol winner since season four.

Amy: Do you realize what's happening here?
Sheldon: Yeah, I do. They're filling up on bread and ruining their meal.

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.

Leonard: Hey.
Penny: Hi, how was the screening?
Leonard: Oh, Sheldon invoked Rosa Parks to make somebody who cut the line feel bad, but only the white people felt bad.
Penny: Ugh, I should've never bought him that colouring book that explains Black History Month.

Sheldon: She's still not answering.
Leonard: My father's not texting me back.
Penny: 'cause they both turned their phones off.
Sheldon: I don't like this at all.
Leonard: I don't like it either.
Penny: Really? 'cause I love it.
