When Michael returns to the office in the final scene, there is a printout of a poster taped onto the wall that reads "Workers Love Nellie," which was a repeating joke during season 3, referring to the previous posters the Bluths have made: "Family Love Michael" & "Family Love Rita."
The information for Nellie in George's secret file says "Nellie -- Conslutant". A bit of foreshadowing for her career.
Nellie Bluth is played by Justine Bateman, who is Jason Bateman's (Michael Bluth) older sister.
During the original airing of this episode, Jeffery Tambor appeared as himself in an ad for Progressive Insurance.
(Michael is talking to Nellie)
Narrator: Hey, let's see what some of the other folks are up to.
(Shot of George Michael doing homework)
Narrator: Nothing there.
(Shot of George, Sr. clipping his toenails)
Narrator: Or there.
(Shot of Buster's nurse getting into bed with him)
Narrator: Oh, my ... Let's get back to Michael.
Lucille: Michael. What a surprise.
Michael: Really? Were you expecting somebody else? Maybe, uh, one of your two daughters?
Lucille: Oh, Lindsay and Tobias never visit.
(Lucille's necklace has just stuck to the magnet)
Lucille: That's not a real gold necklace, is it?
George, Sr.: Well, it wasn't really your 50th birthday.
Tobias: I find myself attracted to someone who is not my wife.
Michael: What's her name?
Tobias: Michael. ... Can you believe it?
Michael: Lindsay, I can tell that it's real. It's like that feeling that you read about twins having.
Lindsay: We're twins. You didn't give me access to the banking.
Michael: No, you'd just ... you'd go out, and you'd just whore it up Lindsay, you know? Now, she's different. She's a little bit more like me. It's like we finish each other's --
Michael: ... Sentences. Why would I say --
Michael: (nods) That time, I was going to say sandwiches.
Maeby: I'm worried you're taking this too seriously.
George Michael: (huffs) Are you ... just the opposite.
("Here Comes the Bride" plays from Maeby's cell phone, George Michael chuckles and looks away)
Maeby: (turns off phone) What the hell is that?
George Michael: I bought you a wedding ring ... tone. (chuckles) Opposite of serious.
Michael: What the hell is going on? Nellie is not a, uh, uh, a prostitute.
Gob: Of course, she is. Oh, but I can see where the misunderstanding is. You didn't know. (yelling to Nellie in the background) Maybe we can give him a family discount!
Michael: Family discount is right, Gob. This is the sister I've been talking about.
Gob: Maybe I should have been getting a family rate ... (breaking down) Oh, my God.
Gob: The real problem is she keeps saying God is going to show me a sign, the ... something of my ways ... wisdom?
Michael: Even if we're not related, I think I would like for you to work here. You're very, very good at it. What you do for a job is not really a great way to make a living, you know?
Nellie: I make 300 grand a year.
Michael: Marry me. It's weird on so many levels.
Michael: You know, Gob, this might be that sign from God that you should change your ways.
Gob: No, I think that's going to be something big.
Gob: A lady of the evening. Working girl. She turns illusions for money ... tricks.
Tobias: Oh, God, here she is.
Michael: Next to that guy?
Tobias: What guy?
Michael: That guy.
Tobias: No, that's her.
Tobias: That's a girl. I think the name "Michael" is making you look for a man.
Michael: I think I'm looking at a man.
Tobias: Michael, look, this has got to stop. I mean, flattered? Yes. Interested? Not tonight.
Michael: (into the phone) Really? And all the guys like her, huh? That is - that is - that is great. Uh, you mean "away," though, right? Because, otherwise, it sounds a little different, but, uh, that's, uh, that's outstanding. You forgot to say "away" again. But listen, let me call you back in a bit, ok? Bye. (to Lindsay) Nellie has blown them all away.
Narrator: But she did have a list of won'ts.
Nellie: We're gonna have some ground rules first, ok? No (bleep bleep bleep) or (bleep). And no (bleep) unless you're wearing a (bleep) or you (bleep bleep). If this winds up on the Web, I will (bleep) you in the (bleep).
Ted: Our computers don't even work on the internet.
Nellie: Well, I was buried in loan debt from business school, so I started whoring myself out.
Michael: I-I'm not interested in you that way.
Tobias: What way?
Michael: Pick one.
Michael: Gob, listen. Can I ask you a question? Do you remember growing up with a sister?
Gob: Sister? Uh ... No, I don't. Not really ... ringing any bells.
Michael: Other than Lindsay, of course.
Gob: Oh! Lindsay!
Michael: Well, you might not be the most reputable source on this.
Lindsay: Oh, you know what? I've already prepared a list of "won'ts."
Tobias: Oh, you're not going to believe this. My list is of "can'ts."
Michael: Marital love can be so romantic.
Lindsay: Well, you know, maybe I would be more attracted to you if you were in better shape. You know, if you were just more muscular and masculine. Does that make me shallow?
Tobias: No. I was going to say the same thing to you.
Tobias: Yes. Lindsay and I are planning a night of heterosexual intercourse.
Michael: You can just say intercourse.
Lindsay: Well, why don't you just go to Dad and ask him who Nellie is, point-blank?
Michael: So, he can just cover it up and lie? I can't stand to hear one more lie out of this family.
Tobias: Oh, there's the woman I'm sexually attracted to.
Michael: Ok, but that's the last one.
Michael: That might be an older sister that we've never met.
Lindsay: Wow! Look at the beak on that bird.
