Martin: What the hell is throat singing?
Frasier: Oh, Dad, it's an extraordinary technique where a single vocalist can actually produce two distinct tones simultaneously, allowing him to harmonize with himself.
Martin: Kind of like the Everly Brothers.
Frasier: If they shared a throat and came from Mongolia, yes.

Frasier: Niles, why aren't you going?
Daphne: He's taking me to see Billy Joel.
Frasier: Billy Joel?
Niles: He's the Piano Man.

Niles: You know, Frasier, you could catch the first two hours of throat singing and still get back in time to walk Eddie.
Frasier: Oh, Niles, you know damn well their throats are just starting to warm up after two hours.

Martin: I'm leaving! [they continue arguing] Shut up! You ought to be ashamed. I can't even depend on my own kids.
Frasier: But, Dad...
Martin: You two, come here. [points to his feet]
Frasier: We're sorry.
Niles: Frasier started it.
Martin: I'm going to work now. I'll be home late. [kisses Frasier on the cheek] Don't wait up. [kisses Niles on the cheek]

[flashback to Martin's later days on the police force:]
Martin: What's up?
Niles: You know very well what's up. Maris just called me. You booted her car.
Martin: Oh, yeah, I remember having a car booted earlier. It was parked kind of close to a hydrant. Was that hers?
Niles: The license plate says "MARIS"!
Martin: It's a very common name, isn't it, Frank?
Frank: My mother's name is Maris.

Daphne: Well, look at you, Mr. Security Guard.
Niles: Yes, beware, criminals. Martin Crane is back on the streets.
Martin: Yeah. Actually, Martin Crane is sitting on his butt in a fancy lobby, staring at a bunch of monitors.

Niles: Dad, uh, are you, uh, you ready for all this, you know? Going back to work?
Martin: Niles, we talked about this. It's only three nights a week.
Niles: Oh, I know, I know, but, uh... You're going through your old routine. Putting on the badge, going back on duty. You're even going to be working with some of your old friends from the force. Just be aware, it, uh, it might bring up buried memories.
Martin: Like what?
Niles: Well, the last time you worked, some crazy person pointed a, uh, a, uh... You know, at you, and you were almost, uh... You ended up in the, uh, the, uh... [starts fidgeting] Well, you could've, uh, could've, uh, you could have actually... Well, I just- Probably you're going to have a lot of issues. [stops fidgeting]

Martin: Well, thanks for being concerned, Niles, but, trust me, I don't have any buried memories. I remember every detail of that day.

Daphne: Honey, get a picture of your father with his thermos.
Martin: Oh, enough with the pictures. People didn't make this much fuss when I shipped off to Korea.

Martin: Who's going to walk Eddie? I told you he has to be walked every night at ten.
Frasier: Yes, yes. Of course, Dad. Of course, Dad. Uh, well, you know, customarily this would fall under the description of, uh... Daphne's job.
Daphne: Customarily, Dr. Crane, it's not my job. I do it as a favor for your father.
Frasier: Will you do it as a favor for me?
Daphne: No.
