Continuity mistake: Near the end of the show, Roz and Frasier are at the radio station, in his booth. There is a clipboard lying on the console to the left. Roz goes to her booth (without the clipboard) and Bulldog bursts through the door on the left. The clipboard has disappeared. Shortly afterwards Roz goes back into Frasier's booth and the clipboard is back where it was.
Continuity mistake: When Roz and Daphne are in the kitchen, the tea cup turns about 45 degrees so we see much more of the flower pattern from the same camera angle. Neither of them touched it.
Continuity mistake: While Daphne and Roz are talking in the kitchen, Daphne takes a carton of milk out of the fridge - and puts it down on her left - in the next shot it is on her right (with no change of camera angle).
Continuity mistake: The shot after Roz says "Roz Doyle, radio producer, single" shows the guy nearest to the window in the other room with his left hand next to his mouth and the woman next to him with her hand next to her chin. The following shot shows the man closest to the window with both his hands next to his mouth and the woman sitting next to him with her hands on her lap. (00:07:35)
Continuity mistake: Frasier knocks the drinks over in Manu's newspaper stand. They had been sitting on a plastic tarp over some newspapers. In the next shot the plastic tarp is draped much differently, covering the papers more. No one touched it in the meantime.
Continuity mistake: Frasier is having a glass of sherry, sitting on his couch, talking to Niles and Martin. As Marty says "let's go have dinner", Frasier throws his hands up - in real life he would have still had the sherry in his hands. There was no time for him to have put it down.
Continuity mistake: When Manu pulls down the metal front over his kiosk, Frasier has his umbrella in his right hand. By the time Manu pulls it all the way down and catches his hand under it, Frasier's umbrella has shifted to his left hand, even though he never transferred it.
You Can Never Go Home Again - S3-E24
Continuity mistake: The flashback is set in 1993, but all the characters look the way they did three years later. Most noticeably, Frasier's hair is short and not long and wavy like in the first season. Daphne's appearance has changed quite a bit too.
You Can Never Go Home Again - S3-E24
Continuity mistake: Daphne is on the phone with her mother and has a dust rag in her hand. She holds out the phone towards Frasier and when the shot goes back to her, the rag is all bunched up in her hand - it has been loose before. There was no time for her to change it.
You Can Never Go Home Again - S3-E24
Continuity mistake: Niles and Frasier are at Marty's old apartment and Niles sits down on the couch. Eddie is sitting next to him, staring. During this scene, the shots of Eddie show him moving from fairly close to Niles, to about 10 inches away, and then back again. He has no time to change position naturally.
You Can Never Go Home Again - S3-E24
Continuity mistake: Roz has a cassette in her hand as Frasier says "call-screening squelches all that," - and the next shot shows no cassette in her hand, without time for her to get rid of it.
You Can Never Go Home Again - S3-E24
Continuity mistake: When Frasier turns up to the office on his first day, having never met Roz before, he has the briefcase that Roz got for him as mentioned by Roz and Niles 'Fool Me Once, Shame on You, Fool Me Twice...'. How can this be if they've never met before?
Other mistake: The guy who plays Clive in this episode has one of the most appalling accents I have heard. He's apparently from Manchester, but sounds like a sort of cockney South African. His accent slips around all the time; it's very poor. I wouldn't normally submit it, but his is so shockingly bad I doubt anyone would be fooled into thinking he was British.
Suggested correction: I think this may have been deliberate. The episode is almost meant to be ridiculous, with the characters quickly churning out lies on the spur of the moment, and everyone supporting the fake family story without objection.
Plot hole: In this show Daphne's former fiance, Clive, shows up. They had been engaged for several years in England. However, in Series 1, episode 11 (Death Becomes Him), Daphne talks about never having had a serious boyfriend, and goes into some detail about how people tried to set her up with eligible men. As Daphne is open about everything else, there seems to be no logical reason for her to not mention she'd been engaged.
Continuity mistake: Frasier is in the kitchen pouring mini chocolate chip cookies from a bag into a bowl while talking to Daphne. The motion of him pouring (and the sound) doesn't stop while he talks but when the shot changes the bag is on the counter next to him.
Continuity mistake: While Niles, Daphne, and Clive are sitting on the couch talking, the large book on the coffee table goes from closed to opened during the scene, even though no one touches it.
Continuity mistake: When Clive arrives at the apartment, he puts his coat over the front of the arm of the couch. As the scene progresses and Marty tells him about being an astronaut, the coat is suddenly on the back of the arm of the couch, even though no one moved it.
Continuity mistake: Bulldog goes into the booth towards the end of the show, and puts his gong and cowbell on the console to his left. When he says "attention, sports fans", the cowbell has suddenly shifted to being in front of him, even though he didn't touch it.
Continuity mistake: Sharon and Bulldog are arguing about golf at Cafe Nervosa, and she has her arm outstretched on the table. As Bulldog says, "If we leave right now", her hands are folded together on the table, without enough time for the change.
Continuity mistake: During the opening credits, Bulldog is on the phonein the hall at KACL and he throws a tennis ball at Frasier, who stumbles around trying to catch it. During the scene we see an extra behind Bulldog go into one of the rooms - but we see her do it again just a split second later - and the second time she has a paper under her arm, where she had nothing the first time.
