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.

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.

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.

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.

Raj: Howard, there must be someone at the university you can go to for help.
Howard: Are you kidding? They're probably the ones who leaked it to the military in the first place.
Raj: What about the guy on the Channel Four News? You know, Four on Your Side? Maybe he can be on your side.
Howard: I'm being harassed by the government, not trying to get to the bottom of a dog-walking scam.

Bernadette: Who's going to officiate?
Penny: I was kind of hoping you would.
Amy: Wait, now I'm just some lousy maid of honor?

Penny: Um, so listen, I don't know if you have any plans next weekend, but I kind of promised your mom we'd have another wedding ceremony so she could attend this time.
Leonard: Wait, we're gonna get married again?
Penny: Yeah, kind of, but now we can invite our friends and family.
Leonard: Seems like a lot of trouble for a hug.

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.

Sheldon: Hey, good news, I just got off the phone with my mother. She is coming to the wedding.
Penny: Okay, wait, you're inviting people to our wedding?
Sheldon: Yes, I'm inviting people to our wedding. Yeah, I've already asked Stephen Hawking and Robert Downey Jr, and, now don't get your hopes up, 'cause he's pretty busy, but Erno Rubik.
Bernadette: Who's Erno Rubik?
Sheldon: Seriously? He invented the Rubik's Cube.
Penny: Okay, fine, but why would you invite him to our wedding?
Sheldon: Because, despite his fame and fortune, he strikes me as a lonely man.

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 ...?

Mary Cooper: It was so nice of Leonard and Penny to invite me.
Sheldon: Well, actually, I-
Amy: It sure was.

Beverly Hofstadter: Penny, I hope the example of my failed marriage to Leonard's father doesn't discourage you from the commitment you've made to one another.
Penny: No, of course not.
Beverly Hofstadter: Although Alfred and I had a lot more going for us than you two.
Leonard: Mom, please save something for the toast.

Mary Cooper: So, Alfred, what is it that you do for a living?
Alfred Hofstadter: Oh, I'm an anthropologist. I study ancient peoples and cultures.
Mary Cooper: My goodness, so all the way back to the Flood.
Sheldon: Don't laugh, she wasn't joking.
Amy: Play with your phone.

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

Penny: Okay, so it's not a legal ceremony, it's just a chance for us to redo our vows so everyone can be part of it.
Amy: So there's no maid of honour?
Penny: No.
Amy: Huh. But if I were to, say, wear a purple satin dress with a sweetheart neckline and stand near you, you wouldn't be able to stop me, right?
Penny: I don't see how I could.
Amy: Then I graciously accept.
