Three Faces of Frasier - S7-E21
Continuity mistake: During the opening credits, Frasier, Martin, and Daphne are sitting at the table talking about getting older. At one point Martin says "when people reach our stage in life" and his left hand is holding his coffee cup. But as the camera cuts to Frasier we can see Martin's hand in the left corner of the screen, up in the air, without the cup. The next shot shows it back on the table, holding the cup again. All this happens too quickly for the changes in real time.

Continuity mistake: Dr. Myshkin arrives at Frasier's from the Russian embassy to discuss the bear clock. He puts a diary on the coffee table where it sits to the right of the vodka, near Niles.

Dark Side of the Moon - S7-E22
Continuity mistake: Near the start of the episode when Frasier comes home, Daphne quickly clears all the beer cans and mess on the lounge table. After she asks Frasier how he is and he replies, "Where's Simon?". The next time we see the table the cans and all the mess on the table have reappeared.

Roz has her arms folded in front of her, but in the next shot she is leaning back with her arm behind her and her hand on the couch.

The Tigger puppet goes from one side of the table to the other and the little teddy turns around 180 degrees.
Whine Club - S7-E17

Continuity mistake: Frasier is sitting on his couch with Poppy, dropping hints about having an arts show on KACL - she has her hands folded on her knee. As Daphne says "he means your mother", the shot changes, and Poppy is suddenly holding a glass of wine, with no time for this to have happened.
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.
