Revealing mistake: Towards the end of the episode, as Frasier is on the lounger by the windows, a power cord is on the ground going through the far left window (where glass should be), possibly going to the lamp.

Continuity mistake: Bulldog is listening to Frasier talk to Madeline on the phone. Bulldog is holding the magazine under his arm, but in the next shot it is on top of the tape player and his hand is on top of it. There was no time for natural change.
Adventures in Paradise (1) - S2-E8
Continuity mistake: Frasier goes into his booth and puts down the magazine featuring Madeline with the page open. Bulldog comes in and looks at the page, and says how attractive she is. But it is definitely not the same page that Frasier had been looking at a couple of shots before.
Adventures in Paradise (1) - S2-E8
Continuity mistake: When Frasier comes into the living room, Marty's cigar box is open. The shot then shows Frasier talking to Eddie about his socks, and the cigar box is suddenly closed. At the end of the scene, the cigar box is open again.
Adventures in Paradise (1) - S2-E8
Continuity mistake: When Frasier is first looking at the magazine article featuring Madeline, we can see the page opposite the one he's looking at. The next shot shows a different page, even though he is supposedly looking at the same one, all the time exclaiming about how great she is.

Continuity mistake: When Frasier and Martin are leaving Artie's hospital room, Frasier has the door about one-third open. Just before they leave, though, as Frasier says "next time he'll stay longer", the door is open much wider. Nobody opened it wider during that time. (00:08:50)
Continuity mistake: Martin is drinking a glass of milk which is between his arm and a bowl of chips. Suddenly the milk is sitting well to the left, even though he didn't touch it. (00:14:35)

Continuity mistake: During the scene where Martin is apologizing to Artie in the hospital room, the photo of Artie's wife on the bedside table changes position about 45 degrees while they talk.
Audio problem: Frasier is talking to Elliot on the phone and there is a shot of Roz. In the shot of Roz, Frasier says "You know, Elliot..." and his reflection is visible in the window. But his lips on the window reflection don't move until after he says "You know, Elliot..." (00:00:30)
Continuity mistake: As Frasier is leaving Roz's apartment, we can see her crutches behind her, leaning together and upright against the wall. In the next shot one has noticeably changed position but they go back to their original state a couple of shots later. (00:04:35)
Continuity mistake: Roz is at Frazier's while Daphne massages her foot. They are talking about Bulldog and we can see one crutch behind her. When she says "I did not", there are two crutches behind her. Later in the scene it goes back to one crutch. (00:07:50)

Fool Me Once, Shame on You, Fool Me Twice... - S2-E14
Continuity mistake: Frasier meets Heather in the bar. She is reading a book which she has propped open on the bar, but as they talk, she takes it off the bar and closes it in her lap. A couple of shots later we see book is back on the bar and she is closing it again. (00:16:25)
Fool Me Once, Shame on You, Fool Me Twice... - S2-E14
Continuity mistake: In Cafe Nervosa, Frasier has just checked the priest's briefcase, think its his own. In one shot his hands are down by his side but in the next split second his left hand is up at his neck and then patting his tie.
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.
