Niles wants to take Daphne to a restaurant called "Au Pied du Cochon". In French, this means "The Pig's Trotter" or "The Pig's Foot".
Niles says on Daphne's wedding day, to Martin and Frasier, that he told her he loved her on his three-day wedding anniversary, making Daphne's wedding his four-day anniversary. At Nervosa, Mel says it's their four-day anniversary, when at this point one more night has passed and it's now five days since they married.
Daphne: And what about Niles' dignity?
Frasier: Well, Maris got that in the divorce.
Niles: (silently mouthing) Very funny.
Donny: I'm gonna hit you with intentionally negligent infliction of emotional distress. Layman's terms: I'm gonna sue your ass off!
Daphne: (about Simon) I suppose he followed that up with some sort of clumsy advance?
Roz: Oh, he tried, but I told him to get lost. Then he hit on my babysitter. She showed him why she's the star of her JV soccer team.
Daphne: You know, Mum claims he was dropped as a child. I think he was thrown.
(Niles and Daphne are deciding where to run off to)
Daphne: Well, to the right is Seattle, and to the left, I guess, is Canada.
Niles: Any thoughts?
Daphne: What's left for us in Seattle? Ex-wives, and ex-fiance. A tangled mess of bitterness and hurt feelings.
Niles: Yes, but an excellent symphony and world-class dining.
Daphne: Then there's Canada: a fresh start, a chance for adventure.
Niles: Grizzly bears.
At the start of the episode when Niles answers his mobile phone, he pauses, and then says, "No, there is no Wendell Vaughn here." Wendell Vaughn is the real name of the Marvel Comics superhero Quasar.
