Radio Wars - S7-E3
Continuity mistake: Similar errors occur in two different scenes: in the first breakfast scene, the coffee pot is sitting on the table but in the next shot Daphne is pouring herself a cup, with no time for her to have naturally picked it up. Later in another scene, Niles is there for breakfast, picks up the pot, and pours himself some coffee. In the next shot, the pot is on the table, again without enough time for him to have put it back.
Continuity mistake: Marty brings a six-pack of beer to the cabin, and puts it down on the table where it stays for the scene - but during the scene one of the cans is sticking out for a few shots, then returns to normal later. No one went near the beer during that time.
To Thine Old Self Be True - S7-E20
Continuity mistake: Frasier goes to get a newspaper out of the curbside kiosk, and catches his jacket in it. He places the newspaper to his right on top of the rack beside it and the shot changes to Regan coming out of the florist behind him. Then we see the newspaper in his left hand, without having time to have picked it up.
Whine Club - S7-E17
Continuity mistake: When Niles and Mel are in his dressing room, Mel puts Niles' jacket on the table in the center. A couple of shots later, the jacket changes position, even though neither of them touched it.
The Dog That Rocks the Cradle - S7-E5
Continuity mistake: When Roz's date Ted returns her purse to her apartment, Bulldog answers the door. He barks at Ted and Ted nervously drops the purse. We see Bulldog close the door. He should have picked up the purse first, or he wouldn't have been able to close it. We do see him drop the purse in a chair as he heads to the kitchen, but we never actually see him pick it up.
To Thine Old Self Be True - S7-E20
Continuity mistake: Early on in the show, Frasier and Martin are having breakfast and we can see an orange napkin in Marty's lap. While he is talking, the camera angle behind his shoulder shows his left hand against his cheek. Right after that the napkin appears on the table to the left - with no time for him to have moved his hand and put it there.
Dark Side of the Moon - S7-E22
Continuity mistake: While Frasier is talking to Daphne about wooing Holly, the wine bottle on the coffee table changes position more than once - from sitting on a book on the left of the tray to being on the bare table on the right and then back again to the left of the tray, but not on the book. Nobody touches it during this time.
Continuity mistake: At Frasier's apartment, Emily asks him if Marty is dating anyone. During the conversation Frasier's hands are in his pockets, and then in front of him, and then back in his pockets, from shot to shot.
Whine Club - S7-E17
Continuity mistake: During the opening credits, Martin and Claire are sitting in Cafe Nervosa, talking. Claire has her left hand and arm crossed over in front of her but when the shot changes and Marty says "you don't think he was watching", her hand and arm are suddenly extended towards him, without time for this to have happened.
Dark Side of the Moon - S7-E22
Continuity mistake: When Roz comes over to meet Simon for their date, she is standing at the door talking and one strap from her shoulder bag is hanging down from the shoulder. The shot from behind her shows both straps are on her shoulder, and then the shot goes back to the front - it's down again. At no time did she adjust it.
The Fight Before Christmas - S7-E11
Continuity mistake: Mel and Frasier are talking at the KACL Christmas party - she says "did you two have a good time last night?" and her hands are down in front of her - in the next shot her hand is up at her neck, with no time to have done this naturally.
To Thine Old Self Be True - S7-E20
Continuity mistake: When Frasier is interviewing the stripper she is leaning on the bed, with her arm behind her. When Frasier asks her about her encore, suddenly her hands are in her lap, with no time natural change.

Continuity mistake: While Frasier is talking to Marty about his friend's funeral, sometimes there is a magazine on the coffee table in front of him, and sometimes there is a pad of paper.
Something About Dr. Mary - S7-E16
Continuity mistake: Niles is showing Marty how he can kick box and he accidentally kicks Daphne. The tray she is covering flies up in the air, and the snack food ends up on the footstool and the floor. There is also an empty basket in front of the footstool. Niles goes to the kitchen to get ice for her wrist; when he returns most of the snack food and the basket have disappeared.
Something Borrowed, Someone Blue (1) - S7-E23
Continuity mistake: Frasier has his arms around Daphne, restraining her from attacking Simon; as the doorbell rings and the shot changes, the bag of cookies that was in her arms noticeably changes position, even though neither of them moved.
Continuity mistake: Poppy is sitting in Frasier's chair in his booth and as she says "all these buttons, how do you do it?", she slaps her hand down on the console. As he begins to answer her, the hand is back in her lap.

The Dog That Rocks the Cradle - S7-E5
Continuity mistake: Bulldog is near Frasier's apartment door with baby Alice and she is facing the door. When Roz walks towards them and asks, "Bulldog do you want a job?", Alice suddenly has her back to the door, with no time for the change.
Continuity mistake: Near the beginning of the show, Poppy meets Niles at Cafe Nervosa. She has a black purse which she places on the table in front of her. During the scene, the purse is sometimes on the table and sometimes isn't, even though Poppy never removes it.
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.
