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: 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.

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.

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.

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?
Answer: It equals the record of James Arness of "Gunsmoke" for the actor who's played the same part on TV NOT in a soap opera. If you include soaps there are two main contenders - William Roache, who's been playing Ken Barlow in "Coronation Street" in the UK since 1960. Don Hastings has been playing Robert Hughes in US soap "As the World Turns" since 1960 as well.
