"Her?" is a commonly said quote by Michael Bluth about his son's girlfriend Ann Veal. Because of her plainness, Michael constantly forgets who she is and when reminded asks Her? because he is not supportive of his son's relationship with Ann.
On a couple of occasions, it is said about another woman other than Ann.
Michael: George Michael, I’d love for you to come with me when I cut the ribbon at the new house.
George Michael: Oh, wow. Hey, can I bring Ann?
George Michael: Ann. You know, she’s... She’s the girl I’m kind of hanging out with.
Michael: I haven’t met Ann.
George Michael: Yes, you have.
Narrator: Michael had met Ann.
George Michael: You let her in. See, that’s ... That’s her right over there.
Michael: Oh, Ann. Yes, yes, yes, yes, yes. I know Ann. Hey, you! She’s got a little hard-boiled egg going there?
George Michael: Oh, it’s so cute. She sometimes takes a little pack of mayonnaise, and she’ll squirt it in her mouth all over, and then she’ll take an egg and kind of... Mmmm! She calls it a “mayonegg.” Are you okay?
Michael: I don’t feel so good.
George Michael: You know, I kind of want to buy her a diamond.
George Michael: Ann. I know I can’t afford it, but Aunt Lindsay was telling me about this diamond cream...
Michael: George Michael, I’m sure that Egg is a very nice person. I just don’t want you spending all your money...
George Michael: Ann.
Michael: ... getting her all glittered up for Easter, you know?From "The One Where They Build a House"
George Michael: Oh, I can’t; I’m meeting Ann.
George Michael: Ann. You took this picture of us in front of that bagel place before it was burned down.
Michael: I guess I thought she was with another family.
George Michael: She’s kind of my girlfriend.
George Michael: Do you not like her?
Michael: I don’t know her, you know? It’s like you spend all your time with her. It’s like you’re hogging her. Like you’re a little Ann hog, okay? Don’t be such an Ann hog.From "¡Amigos!"
George Michael: Oh, my God, that’s Ann.
George Michael: It’s the girl who ripped my heart out. The girl whose face will always be etched in my mind.
George Michael: She’s really funny.
George: Well, let’s hope so.From "Good Grief"
Michael: Listen, you know I would never date anyone without you being okay with it, right?
George Michael: Yeah, and you don’t have to do that.
Michael: Great, because I didn’t do it this time. I kind of reconnected with that blind prosecutor I used to date, Maggie Lizer.
George Michael: Her?From "Hand to God"
Lindsay: So, you were listening in on George Michael. Can you believe what he asked me this morning?
George Michael: Hey, do you think my mom’s engagement ring is still around?
Lindsay: Of course it is. Your father would never part with something so precious.
Narrator: In fact, Lindsay was currently wearing it on her middle toe— “roast beef.”
George Michael: I’m thinking of asking Ann to get pre-engaged.
Lindsay: You are?
George Michael: Yeah. I feel like God moved her here from Ohio just to be with me.
George: [Listening from the attic] Her?

Michael: I am getting married.

George: Howdy doody, that’s it. Now you get back here so you can smuggle me out past the guards before Michael starts blabbing.
Lucille: You know what? You can smuggle yourself out. You want to get away from me so bad, you’re free. But I’m free, too, baby. I’m staying in the conjugal trailer with the warden tonight.
George: Him?From "Prison Break-In"
Tobias: Oh, God, here she is.
Michael: Next to that guy?
Tobias: What guy?
