In this episode, Niles sneers at the quality of the Spanish leather his belt is made of. However, in the first season episode 'Fortysomething' (1x20), Niles complains to Martin about Eddie slobbering all over his shoes, made especially by an "old blind cobbler in Seville [in Spain]".
Numerous references are made to the fact that Frasier hasn't been with a woman since the previous Christmas. This is in fact true, and the woman in question was Kate Costas (Mercedes Ruehl).
Frasier: (filling in for Bulldog) Hello, You're on the air.
Caller: Yeah, you think it was a good idea for the Sonics to give up those draft choices so they could free up some money under the cap? You know, to go after a wide body to help them in the paint?
Frasier: (thinking for a while) Yes! (then cuts off the caller)
Frasier: Eh, Ok, sports enthusiasts. This is Dr. Frasier Crane filling in for Bob 'Bulldog' Briscoe. (bashes bulldog's gong. It topples) You're on the air!
Caller: This is Mike. I wanted to talk to Bulldog, but you'll do. So, what's your take on the damn Yankees this season?
Frasier: (pauses to think) Are you speaking of the, the frothy musical adaptation of the Faustian myth or, or the baseball team of which I know nothing?
Caller: What a weenie. (hangs up)
Martin: (to homeless man) Not You. We're talking about Muckabies.
Homeless Man: Oh. Great Shoes. They used to sell them here.
Martin: What happened to the store?
Homeless Man: Moved.
Daphne: Do you know where?
Homeless Man: Yeah, it'll cost you.
Martin: How much?
Homeless Man: No, not money! I want a kiss.
Martin: You heard him.
Daphne: Mr. Crane.
Martin: You burnt them, you owe me. It's only a kiss.
Homeless Man: Not her! (begins smiling and raising his eyebrows at Martin)
(Martin shuffles behind Daphne, with a bewildered look on his face)
Niles: I had an abysmal day. Remember the ad I placed?
Frasier: Oh yes - 'Dr. Niles Crane, Jung specialist', blah, blah, blah...
Niles: Yes. Well, they've made a tiny little typo. See if you can find it.
Frasier: (reading)'Dr. Niles Crane... Hung specialist'... Oh, my!
Niles: The rest they got perfectly. (continues reading) 'Servicing individuals, couples, groups. Satisfaction guaranteed... Tell me where it hurts!'
Frasier: Well... any calls?
Niles: It's a telethon, Frasier.
