Mary Cooper: Thank you for picking me up.
Sheldon: Oh, you're welcome.
Mary Cooper: I was speaking to your young lady.
Amy: My pleasure, Mrs. Cooper.
Mary Cooper: Oh, please call me Mary.
Amy: Okay, Mary.
Sheldon: You know, that doesn't work for me, let's stay with Mrs. Cooper.
Mary Cooper: Sheldon, don't be silly.
Sheldon: Wh-, what? That's what I called you 'til I got to know you better.

Leonard: Oh, we have to use the stairs.
Alfred Hofstadter: When are they gonna fix your elevator?
Leonard: Uh, I don't- Any day now.
Alfred Hofstadter: Well, the stairs are fine. Besides, your mother is up there. Maybe I'll have a heart attack and not have to see her.

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.

Leonard: All right, you two, don't start. Penny and I are throwing this second wedding for your benefit. Can you please not ruin it?
Alfred Hofstadter: Of course. I'm sorry.
Beverly Hofstadter: Oh, look at that, you can apologize.
Leonard: Mom.
Beverly Hofstadter: I'm sorry.
Mary Cooper: You know, the Bible says forgiveness-
Sheldon: Mom.
Mary Cooper: I'm sorry.
Penny: Uh, who's hungry? We have a reservation at the best restaurant in town.
Sheldon: It only got three-and-a-half stars on Yelp.
Amy: Sheldon.
Sheldon: I'm not sorry. That's true.

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.

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.

Penny: Whew, chilly.
Amy: I think I can see my breath.
Beverly Hofstadter: We can hear you.
Penny: Sorry.
Amy: Sorry.

Penny: Hey, look, then forget about her, let's do it for us. We could keep it small and informal. This time we can invite our families.
Leonard: Is your brother out of prison?
Penny: Thanks to overcrowding, yeah.

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

Leonard: Penny's really looking forward to seeing you.
Alfred Hofstadter: Ah, she's a sweetie. You got a good one there, Leonard.
Leonard: Thanks, Dad.
Alfred Hofstadter: How the hell did you do that?

Howard: I don't know what to do. It's the Air Force. I mean, should I respond to their e-mail? Ignore it?
Raj: You can't ignore it. It's not that postcard that says it's time to go back to the dentist.

Bernadette: Come on, Howard, you're overreacting.
Howard: Am I? Am I? What do you want to bet some black ops guy is reprinting my high school yearbook and I'm no longer in it? That chess club picture is now just David Zimmerman and Elaine Cho.

Howard: I'm sorry, you find this funny?
Raj: No, I was just thinking about Jurassic World. Boy, that was terrible.

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.
