Frasier mentions Lilith's affair with 'a Frenchman who lived in a self-contained underground eco-pod,' Dr. Louis Pascal (played by Peter Vogt), from the Cheers two-parter "Teaching with the Enemy" and "The Girl in the Plastic Bubble".
In one of the first scenes, Roz is in her booth at KACL and takes out her lipstick and compact and she is shown uncapping the lipstick. Then it cuts to Frasier reintroducing Niles to her, and we see her uncap the lipstick again.
Daphne: Oh, I love to see old family photos. My goodness! What a handsome, sinewy young bloke!
Frasier: That's our dad.
Daphne: You two take after your mother, don't you?
Frasier: (reading aloud from Niles' boyhood journal) "Though summer at the lake seems but a vapid, vacuous experience, it is a necessary tonic for my troubled youth." (turning to Niles) Niles, how old were you when you wrote this?
Niles: Almost nine. Which explains the redundancy with "vapid" and "vacuous." By ten, my writing had gotten considerably tighter.
Frasier: Among other things.
Daphne: Working down at the docks has always been a tradition for us Moons. My father worked on the docks, and me grandfather before him. All my brothers do. Well, except for my brother Billy. He came home one day, and announced he hated the smell of fish and was going to teach ballroom dancing. And he did. And he does. He's my mum's favorite. Dad mostly flicks the crust off his kidney pie at him.
Martin: How much longer do I have to do this?
Daphne: Be patient. You don't want to go through life dragging your leg behind you like a dead tree branch
Martin: I'm talking about listening to your family's history.
Frasier: Thank you Niles, but I think I just need a night to myself.
Niles: Well, if you change your mind it should be a hoot. As we speak, I'm wearing oversized polka-dot boxers and quick-release suspenders.
Niles: Hello, Daphne.
Daphne: What brings you here?
Niles: A rental car, thanks to my brother.
Frasier: What are you staring at?
Daphne: Have you ever thought about growing a moustache?
Frasier: No, I don't think it would suit me.
Daphne: Oh, yes it does.
Frasier: You've never seen me with one.
Daphne: Actually, I have. There's a billboard for your show down on Sixteenth Street. Some kids went at you with a can of spray paint.
Frasier: And it looked good?
Daphne: Oh, yes. But a word to the wise--take good care of your teeth. That look is not at all flattering on you.
Niles: Oh nothing, I just realized if Dad's eating here this can't be a very good restaurant.
Niles: I mean, I could get just nip back to Crabtree & Evelyn and buy a bar of lavender soap, just to be safe. (stands)
Frasier: Oh Niles, Niles. Sit down. Lavender soap--for God's sake, you're a man, you'd look ridiculous.
Waitress: Can I get you a drink?
Frasier: Fuzzy Navel, blended nice and frothy, please. And a...martini, Niles?
Niles: Right. What shall we do?
Niles: Perfect. No place fancy, I'm sure neither of us wants a heavy meal with lots of wine and expensive desserts.
Frasier: Oh, it's your turn to pay, isn't it?
Niles: You know me so well. (they leave)
Niles: Hello, Frasier.
Frasier: Hi, Niles. You remember Roz.
Niles: Yes, of course. (shakes Roz by the hand) What brings you here?
Roz: Just passing by and thought I'd stop in for a career.
Niles: Good luck. (to Frasier) Sorry I'm late, Frasier, but the entrance to your parking garage is blocked by a cab driver with a ponytail, scraping gum off his back seat.
Roz: For your information, this guy happens to be a very successful media consultant. He graduated from Princeton, he has a house on Mercer Island and he owns a forty-foot sailboat.
Frasier: You met him on a bus, didn't you?
Roz: No. Actually, we shared a cab... Alright, he was driving it.
Frasier: Roz! Aren't you screening these calls?
Roz: Yeah. But when you only have one, you get a little less particular.
Niles: Well... it's times like this that most families pull together and draw strength from each other. (pause) What shall we do?
Frasier: Doesn't it bother you that your father cheated on my mother?
Niles: Frasier, your loyalties are seeping through, and I might point out that I got Mom's small features, while you got Dad's chunky thighs.
