Continuity mistake: In the initial scene where Frasier is talking to Daphne and Roz in Cafe Nervosa, Frasier can be seen wearing a wedding ring in certain shots. (00:01:10)
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.
Continuity mistake: When Frasier and Poppy are sitting on his couch having a drink, the level in the wine bottle goes down and up and down throughout the scene, with no logical reason.
The Kid (2) - S5-E4
Continuity mistake: During the scene where Frasier and Roz are talking at her apartment, the mug that had been sitting on a tray moves off the tray and is sitting right on the table.
Continuity mistake: When Frasier is talking to Claire in the store by the CD organizers you can see a wedding band on this finger. In the next shot it is not there and then it is back on again.
Something About Dr. Mary - S7-E16
Continuity mistake: When we first see Daphne's wrist brace it is on her right arm. In the end credits it's now on her left arm.
Continuity mistake: Why can Lilith hear what they are saying through the door? In several other episodes, the characters have had arguments or insulted the person at the door without them being able to hear. Yet here suddenly it's possible for her to hear.
Roz, a Loan - S6-E9
Continuity mistake: Frasier and Niles are talking to Marty about the spa. As they speak, the magazines on the coffee table shift about 6 inches even though neither of them touch them.
Continuity mistake: There was an episode in which Martin attempts to end a feud between Frasier and Niles by telling a story about his detective partner. He starts with the line, "I never had a brother...", but in the episode about Frasier's cousin Nikos getting married, Martin's brother Walt was introduced.
Continuity mistake: During the opening credits, Frasier is playing the piano and Martin is going through papers on the table. When Marty says "I don't know, Eddie, must you?" there is something pink lying on the table. The shot goes back to Eddie and then back to the table, but the pink item has disappeared.
Continuity mistake: Near the start of the show, Roz is in her booth at KACL and takes out her lipstick and compact - we see her uncap the lipstick. Then Niles comes in an Frasier reintroduces them, and we see her uncap the lipstick again.
Continuity mistake: Towards the end of the show, Frasier is explaining to Niles how he was stood up that evening; at the same time he is getting himself a glass of sherry. Niles says, "there was no emergency", we see Frasier repeat the actions to get a glass of sherry all over again.
Space Quest - S1-E2
Continuity mistake: Frasier (and later the others) come back to his apartment to avoid the rain - they shake off umbrellas, and we even hear the storm at the very start of the scene. However there's no rain on the balcony - can't be covered, as we see in "Call Me Irresponsible" during the obligatory sex scene that when it's raining the balcony gets soaked.
The Good Son - S1-E1
Continuity mistake: During the first episode of Frasier there is a painting of some vases in Frasier's apartment which is at the end of the hall leading on to Daphne's Room. In this episode the painting has a red and purple background, however in 'Here's Looking at You' (S1, 2 mins 52 secs) the exact same painting is now red and blue. It remains this new colour for the entire 11 seasons. (00:06:50)
The Good Son - S1-E1
Continuity mistake: In the scene where Daphne first comes to the apartment, the beer can and remote control on Martin's side table change positions between shots.
Continuity mistake: When Frasier and Niles are eating the steaks at the restaurant that Martin brought them to, in some shots you can see Frasier's baked potato, and in others from the same angle it is not visible.
Continuity mistake: When Frasier asks Martin "Where are your pants?", Marty is holding the ice cream carton underneath, but when the shot changes and he answers, "In the fridge", he is holding the carton by the side.
Continuity mistake: When Frasier and Martin are yelling at each other about the mess on the carpet, Marty is holding a red plastic oil container. In one shot there is a noticeable dribble of oil on it, but in the shots before and after, it is clean.
You Can't Tell a Crook by His Cover - S1-E15
Continuity mistake: When Frasier and Martin are looking at Frank examining the bowl, the cards on the table change position.
