Penny: You know, being in a relationship with Leonard also comes with its challenges.
Beverly: Yes. Well, what can you do?

Penny: How long have I had spinach in my teeth?
Beverly: Since the airport, dear.

Beverly Hofstadter: Hello, Sheldon. What a pleasant surprise. How are you?
Sheldon: Honestly, I've been better. Do you have time? Leonard says you're very busy these days.
Beverly Hofstadter: Oh, I just say that because he prattles.

Beverly Hofstadter: What's going on?
Sheldon: Well, our friend Raj moved into my old room, and it's brought up a lot of negative feelings for me.
Beverly Hofstadter: Mm. Well, what do you think the loss of your room represents?
Sheldon: Beverly, you know I hold you in high esteem. Can we skip the part where you pretend not to know the answer, and get to the part where you tell me the answer?
Beverly Hofstadter: Very well, but, uh, if you don't mind, I'd still like to pause for effect.

Beverly Hofstadter: Do you agree with that?
Leonard: Well, now that you point it out-
Penny: Are you kidding me?
Leonard: We do seem to keep finding roommates.
Penny: Now you're taking her side?
Beverly Hofstadter: Dear, I would never come between you and Leonard. That's for your parade of roommates to do.

Penny: Beverly, I have to say, it's so nice seeing the two of you get along.
Beverly Hofstadter: Oh, I've always gotten along with Leonard. Of all of my children, he's the most docile.
Leonard: She wrote that in a birthday card once. I keep it in my nightstand.

Beverly Hofstadter: Yeah, that's a fair point. I hadn't considered your influence. Perhaps tomorrow I could observe the two of you together?
Penny: Uh, "observe"? [laughs] What is going on?
Beverly Hofstadter: I'm just visiting with my son and doing research for my book on how various parenting strategies affected my children as adults.
Leonard: This has all been work to you? Hanging out with me and coming to my lab, I- I thought we were enjoying each other's company, but it was just research.
Beverly Hofstadter: I was enjoying it; you know I love research.

Leonard: I can't believe this.
Beverly Hofstadter: What? You seem angry.
Leonard: Of course I'm angry!
Beverly Hofstadter: Well, so would you say that you're somewhat angry, very angry or extremely angry? Never mind. I can see it in your face, dear.

Beverly Hofstadter: Oh, did I thank you for the flowers?
Sheldon: You did.
Beverly Hofstadter: I don't really like flowers.
Sheldon: Me neither, but it's the social convention.
Beverly Hofstadter: It is, isn't it?

Penny: I'm Penny. I'm his neighbor.
Beverly Hofstadter: I'm Beverly Hofstadter.
Penny: Nice to meet you. *Offers to shake hands*
Beverly Hofstadter: Oh, you're a hand shaker. Interesting.

Beverly Hofstadter: So, have you and Penny set a wedding date?
Leonard: No, we're kind of taking it slow.
Beverly Hofstadter: I see.
Leonard: What does that mean?
Beverly Hofstadter: You've been on and off with this woman for seven years and engaged for one year. One has to wonder if there's a problem. Are you having satisfactory intercourse?
Leonard: Yes, Mother.
Beverly Hofstadter: Only satisfactory. I see.

Wyatt: It's nice to meet the woman who raised this fine young man. I'm looking forward to meeting his father.
Beverly Hofstadter: Prepare to be disappointed.

Leonard: Wait, wait, wait. You had surgery?
Beverly Hofstadter: Yes, and Sheldon sent me flowers.
Leonard: I heard that.
Beverly Hofstadter: Then what was all that "wait, wait, wait" about?

Leonard: See this right here. What you're doing. Can you please not do that around Sheldon's mom?
Beverly Hofstadter: Why, are you attracted to her, too?

Amy: You know, just when I think we're making progress in our relationship, we revert to our old patterns where thoughts and feelings go unexpressed. I mean, if he didn't want to go shopping with me, why didn't he just say so?
Beverly: Maybe he couldn't get a word in edgewise.
