Three Dates and a Breakup (1) - S4-E19
Continuity mistake: Sherry is about to tell Frasier and his date a joke - Marty and she have their arms around each other - the first shot shows her large orange purse is over her shoulder (between them) and behind her but the next shot shows it still between them, but in front of her - simply impossible to have changed its position so quickly.

Continuity mistake: During Frasier's party, he is talking to Kimberly by his credenza. At the end of the scene, a wine glass appears there - it hadn't been there earlier. The glass Kimberly put down was a champagne glass.

Continuity mistake: After Roz says to John, "I hardly recognized you with that mustache", one hand is up by her chest and the other is on her knee, but when the shot changes, both hands are clasped together.

Continuity mistake: Frasier's plastic container of veal rotates about 45 degrees between the time Stephanie gets up and the time she reaches to door - and no one touches it during those few seconds.
Three Dates and a Breakup (1) - S4-E19
Continuity mistake: When Martin and Shelly are having a fight, Frasier puts a small bag down, which is yellow on one side and has a logo on the other. He puts it down with the yellow side facing us, and for a several shots it stays like that. However, when Martin is talking about "things that bugged me," you see the bag has inexplicably rotated so the logo is now facing us.

Continuity mistake: Near the start of the show, when the waitress gives Frasier the tickets for the show, she has a dark blue dish towel over her left arm, but as Frasier walks away, it is no longer there.

Continuity mistake: At Cafe Nervosa, while Roz is praying her old school mate won't recognize her, there is a crumpled up red napkin on the table. When he comes over to talk to her, it has magically disappeared.
Three Dates and a Breakup (2) - S4-E20
Continuity mistake: While Marty and Frasier are fighting Marty smashes some plates. The shot changes to the living room with Frasier apologizing and then switches back again. However, now all the smashed crockery has disappeared to be replaced by what looks to be a bowl and a tumbler.
Three Dates and a Breakup (2) - S4-E20
Continuity mistake: As Frasier pushes Sherry towards the balcony, we can see a gold decorative thing on her green purse. In previous shots to this, the gold piece didn't show, because the other side of her purse was facing out. At no time did she turn the purse around.
Three Dates and a Breakup (2) - S4-E20
Continuity mistake: Niles and Frasier have drugged the rottweilers with some of Maris' pills and Frasier points towards the french doors and says, "The dogs are getting drowsy." We see the dogs dropping to the ground. The next shot of the doors, a couple of seconds later, shows no sign of the dogs, although they were visible from that angle just before that.

Continuity mistake: While Frasier and Marty are in the kitchen arguing about Sherry, his can of beer moves from the right side of the counter quite a distance over to the left of the dishes he broke. The sugar bowl and jam pot also change positions during the same shots.
Three Dates and a Breakup (2) - S4-E20
Continuity mistake: When Marty is explaining why he broke up with Sherry, we can see his blue jacket hanging up on the book by the fireplace - as he says "I said it back", the coat is no longer there. It does reappear in later shots.
Three Dates and a Breakup (2) - S4-E20
Continuity mistake: Frasier's third date, Leslie, shows up at his apartment wearing a long off-white coat. He hangs it up beside the fireplace; for the rest of the scene we sometimes see the coat hanging with the left sleeve straight and sometimes with the left sleeve all crinkled up.
Other mistake: When Frasier enters the apartment, Martin and Sherry are talking in the kitchen. If you listen carefully to what they're saying, their conversation makes no sense. Martin says something along the lines of "Daphne is really a very nice girl" before suddenly, in a very different tone of voice, he says "You're right, we're not getting enough privacy around here". Seems like a big chunk of conversation was edited out.
Continuity mistake: During breakfast, there is a bowl of scrambled egg next to Martin that moves itself around, and at one point the fork in it just vanishes and then reappears.
Continuity mistake: Towards the end of the show, Daphne, Niles, Sherry, and Martin are in Frasier's bathroom where he is trying to take a bath. He starts talking to Sherry - she is sitting on the ledge at the end of the tub. From one shot to the next she has her left leg crossed over her right, then her right over her left, and then both legs uncrossed. She did not have time to shift her position and there is no "residual movement" that would have been natural had she been fidgeting while he talked to her.
Continuity mistake: When Frasier and Marty are sitting at the breakfast table, talking about the weather, Frasier's newspaper is sometimes folded over and sometimes not, although he never changes it from shot to shot.
Continuity mistake: Marty, Daphne, and Sherry are all shouting at each other around the dining room table - there are two chairs between Martin and Daphne but when the shot changes to Frasier coming in, now Marty and Daphne have no chairs between them.
Continuity mistake: While Daphne and Sherry are arguing, Marty says, "See, I'm regretting that one already", and his rolled up exercise mat, sitting on the table, rotates about 45 degrees.
Continuity mistake: During the bathroom scene where Frasier is in the bath talking to everyone, the bubbles on his face and shoulders change in position and amount from shot to shot.
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.
