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: 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.

Raj: Okay, look, I'm on the Air Force Web site, and the department that e-mailed you is in charge of acquisitions. So maybe they just want to give you a lot of money for your invention.
Howard: Oh, please, that's not how it works. You saw E.T., Avatar, Jurassic World. The military just shows up and takes over.
Bernadette: You do realize those weren't documentaries, right?

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?

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.

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.

Alfred Hofstadter: I, uh, I would also like to make a toast.
Penny: Aww.
Alfred Hofstadter: Leonard, I am so happy that you have found a woman who loves and cares for you.
Beverly Hofstadter: What the hell is that supposed to mean?
Alfred Hofstadter: Why don't you take a pill?
Beverly Hofstadter: Like you did before sex?
Alfred Hofstadter: What I really needed was a blindfold.

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.

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.

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 ...?

Penny: Well, then it's settled. Yay. So funny. I never thought my second marriage would be to you.

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.

Beverly Hofstadter: How dare you invite your father without consulting me.
Leonard: Sorry, but I don't think I need your permission to have my father at my wedding.
Beverly Hofstadter: You do understand our marriage ended because he had an affair.
Leonard: I know, and there's no excuse for that.
Beverly Hofstadter: He claimed I was cold, emasculating, and hadn't shown him any physical affection for years.
Leonard: I was wrong, there's three excuses for that.

Howard: Hey, I just got an e-mail from the U.S. Air Force.
Raj: Open it.
Howard: Hmm. "We request a meeting at your earliest convenience regarding your quantum guidance system, provisional patent 62/295118." That's weird.
Raj: Is there a window around here we don't know about?
Howard: I'm sure it's just a coincidence.
Raj: Yeah, of course. What else could it be? (loudly) Boy, do I love America!
