The Devil and Dr. Phil - S10-E21
Continuity mistake: When Bebe is talking to Frasier, she is eating a piece of celery. The piece changes size between shots, most noticeably at the very end of the conversation when it suddenly goes from large to tiny.
Revealing mistake: When Frasier and his guest are standing up to leave, the girl behind the counter is watching them for her cue to come over.
Revealing mistake: Even though she has customers in front of her, the barista can be seen watching Frasier and his guest as they are talking, so she can see her cue to come over.
Factual error: When the barista hands an umbrella to Frasier's guest we can see she is wearing platform flip-flops. Health code in Seattle forbids open-toed footwear for employees in food service establishments, which would include a coffeehouse.
Deliberate mistake: The computer Felicity Huffman pushes off the desk is a dummy model and is not connected to anything. When she first pushes the computer off, the monitor only has a power cable visible. These computers were connected via VGA cable that was screwed on; it is quite difficult to disconnect it from the computer. And also when the monitor hits the ground, you hear light sounds of glass breaking and you can see as the monitor rolls that the glass is missing, yet none is to be seen - it's a hollow chassis. Obviously done as the stuff was shoved off in Kelsey's direction so as to avoid injury.

No Sex Please, We're Skittish - S11-E1
Continuity mistake: Roz and Frasier are in his apt. after Julia has left. The small pillow on the far left of the couch is quite smooshed down and almost flat, but when Roz walks over toward the center of the couch, the pillow is much fuller and fluffed out. In the next shot we see Frasier sit down on this pillow; when he stands it looks like it did a few shots before - very flat and smooshed.

Continuity mistake: When Julia answers her cellphone, she bunches up her napkin in her hand, but the next shot shows the napkin lying flat on her lap again; this would be almost impossible to do in such a short time with only one hand free.
A Man, a Plan and a Gal: Julia - S11-E2
Continuity mistake: Martin is standing at the door talking to Frasier about taking Eddie to the vet. From one shot to the next the leash changes position from being over Eddie's head to being under his chin - without enough time for this to happen naturally.
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.
