Beverly Hofstadter: Your check engine light is on.
Penny: Yeah, I gotta put a sticker over that. So, you must be devastated about your divorce?
Beverly Hofstadter: Oh, not at all. Though I am a bit distressed to be a in vehicle that's not subjected to regular maintenance.

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.

Beverly Hofstadter: Well, Leonard's younger brother, Michael, is a tenured law professor at Harvard, and his sister just successfully grew a human pancreas in an adolescent gibbon.
Howard: So, she's close to curing diabetes?
Beverly Hofstadter: Why else would you grow a pancreas in a teenaged gibbon?
Howard: Wow, you must be very proud.
Beverly Hofstadter: Why? They're not my accomplishments. I have to urinate.

Beverly Hofstadter: Leonard, would it make you feel better to hear that your mother approved of your life choices?
Leonard: Yes, it would.
Beverly Hofstadter: Yeah. Well, you should work on that.

Leonard: Just tell me the truth, Mother. Was my whole childhood just one big experiment?
Beverly Hofstadter: Of course not, dear. It was thousands of small experiments.
Leonard: So that's all I was to you, a-a test subject?
Beverly Hofstadter: No, you were my baby and I found you fascinating.
Leonard: Really?
Beverly Hofstadter: Yes, watching you develop, tracking your progress. I know I'm not the warmest of parents, but it was time we spent together, and, honestly, those are some of my fondest memories.
Leonard: When did you stop?
Beverly Hofstadter: Oh, I can't tell you. The experiment isn't over.

Beverly Hofstadter: You know, both selective mutism and an inability to separate from one's mother can stem from a pathological fear of women. It might explain why the two of you have created an ersatz homosexual marriage to satisfy your need for intimacy.

Beverly Hofstadter: Your scan data will be very helpful to my research. You have a remarkable brain.
Sheldon: I know. Although, I've always hated how my right frontal lobe looks in pictures.
Beverly Hofstadter: Common complaint among men. Nothing's ever big enough. Except when they get a tumor, Then you never hear the end of it.

Beverly Hofstadter: In any event, while I've had my misconceptions about *Penny*, Sheldon spoke very fondly of her. And if she is good enough for him, then she's good enough for me.

Leonard: So, Mother, I'm surprised you came all this way for Sheldon's birthday.
Beverly Hofstadter: Oh, I was happy to. He did come to my 60th.
Leonard: Oh, you had a party for your 60th?
Beverly Hofstadter: Oh, I wouldn't call it a party. Just a few close friends. And your sister and brother.
Penny: You know, to be fair, we did get married in Vegas and didn't invite her.
Beverly Hofstadter: And I never did thank you for that, dear.

Penny: It's out of order.
Beverly Hofstadter: Yes, I can read the sign. I was just pondering the implications.
Penny: I think it implies that the elevator doesn't work.
Beverly Hofstadter: Again, I can read the sign. But the sign and the tape are covered with a layer of dust which indicates the elevator has been non-functional for a significant period of time, which suggests either a remarkable passivity among the - I assume - 24-36 residents of this building - based on the number of mail boxes and typical urban densities - or a shared delusion of functionality.

Leonard: How was your flight?
Beverly Hofstadter: There were some parents with a baby. A lot of crying.
Leonard: Well, babies do that.
Beverly Hofstadter: No, it was the parents. It seems they couldn't handle some constructive criticism.

Amy: This isn't about me and Sheldon. This is about Rajesh moving in with Leonard and Penny.
Beverly Hofstadter: Interesting. They've found a need to take yet another roommate. Seems they're avoiding some harsh realities themselves.
Sheldon: I had no idea all our relationships were such a disaster. Boy, you're good.
Beverly Hofstadter: That is the word on the street, dear.

Beverly Hofstadter: Fascinating. How can someone as enlightened as Sheldon come from someone like you?

Beverly Hofstadter: There's something I need to say to you.
Leonard: Oh really? That's too bad.
Beverly Hofstadter: Leonard, I always made you earn my affection. But today I realized that there's more than one way to raise a child.
Sheldon: I taught her that!
Beverly Hofstadter: Therefore, I would like to initiate a new protocol wherein I shower you with unconditional love.
Leonard: Wow. When does that start?
Beverly Hofstadter: So needy.

Beverly Hofstadter: Penny, go on.
Penny: Well, ever since his paper got disproven, he's been a wreck. He's been sad and and angry. He just seems kind of broken.
Beverly Hofstadter: Well, it sounds like he may be grieving.
Penny: Really? Over a theory?
Beverly Hofstadter: Of course. You can grieve over any emotional loss. The more you care about something, the greater the trauma of losing it.
Leonard: Oh, boy. He cared about this a lot.
Penny: Yeah. What can we do to help him?
Beverly Hofstadter: Well, grieving is a process. Every culture has its own rituals and traditions to facilitate mourning. The ancient Egyptians had their mummification, the Tibetans had their sky funerals-
Leonard: And when I was little and my dog died, my mom sat me down and very gently told me that she wished the truck had hit my dad instead.
Beverly Hofstadter: I was trying to lighten the mood. Your dog had just died.
