Three of Daphne's brothers visit from England. However, none of the actors playing them are English: Anthony LaPaglia is from Australia, Richard E. Grant is from Swaziland and Robbie Coltrane is from Scotland.
July 15, 2004, the date the wedding should have been, was not a Saturday.
When Niles drops the ring, Eddie is eating from a plate. On a pulled-back shot, Eddie has licked the plate clean; but on the close-up of Eddie, the plate still has food on it. On the next away shot, Eddie is still licking a clean plate.
Eddie's birthday is May 15 in this episode, but in an earlier episode his birthday is said to be on May 7.
When Niles drops the ring, it can be seen bouncing out of camera range and not into the pate.
Niles: I woke this morning to find Daphne's brothers playing a game called 'I Can Reach It From Here.' Give you a hint, the 'It' was a toilet. And there were no winners.
Frasier: Well, it's very tempting, Bebe, but I'm very happy here in Seattle. I don't want to leave.
Bebe: Darling, it's San Francisco! Do you know what life is like there for a good-looking straight man? You'll be like a Snickers bar at a fat camp!
Roz mentions the "disaster" the last time she took over the show, referencing "Enemy at the Gate", when she let slip she and Frasier slept together.
During the end credits of the syndicated episode, there is an additional scene in which Michael and Stephen Moon talk to Kenny and then show off the watch and wallet they've swiped from him.
The syndicated episode has both cuts and additions:
As Charlotte leaves, she says farewell, returns to reclaim her scarf, returns to claim her cell phone, then returns for a final kiss. The syndicated version omits the scarf, so that Frasier appears to be riled by only her first knock at the door. His "positively quilty" reply is replaced by a fade-out.
In the original version, the wedding guests bustle in from the smelly outdoors and it fades out on the overwhelmed Frasier. In syndication, this is followed by Frasier fretting, "A room full of overheated wedding guests...my Knudsak will be soaked!" (referring to his melting ice sculpture by artist Arthur Knudsak) and Roz, thinking he said "nut sack," assuring him that it won't be visible because he's wearing a black suit.
The vet office Niles and Daphne went to had photos of animals on the wall. In the flashback episode that played before this, the therapist tells Frasier that he had a brother-in-law who was a veterinarian and had pictures of his patients on the walls.
This episode aired at 8:54 PM on a Thursday night.
Several character names are references to "Frasier" writers past and present. The name "Dr. Anne Ranberg" is derived from the Writing/Producing team of Anne Flett-Giordano & Chuck Ranberg, and Bebe mentions a recently-deceased San Francisco radio host named "Mark Reisman," who shares the same name as former "Frasier" Writer/Producer, Mark Reisamn.
Originally aired as an hour long episode.
