Continuity mistake: Frasier and Martin are in the kitchen and Marty gets some chips out of the cupboard next to the fridge. As he leans down to pet Eddie we can see a bag of blue chips still in the cupboard - but when he straightens up to talk to Frasier, we see a red bag in the cupboard, not the blue one (the camera angle remains the same).
A Man, a Plan and a Gal: Julia - S11-E2
Continuity mistake: While they are having dinner at Frasier's, Julia raises her left arm to touch her hair, but in the next shot her hands are both down in her lap.
Continuity mistake: Near the start of the show, Roz arrives at Frasier's with baby Alice. She is standing near the balcony door in her black gown when suddenly a white spit-up cloth appears on her shoulder that had not been there previously in the scene.
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.
Continuity mistake: Nanny G and Frasier are in the kitchen of his apartment and there is a tray with three empty wine glasses. Nanette takes one and pours herself some wine; a few seconds later Frasier grabs the tray and goes into the living room, but now he has four empty glasses on the tray when there should have only been two. At no time did he add glasses to the tray.
Continuity mistake: When Frasier and Luke are on Luke's boat, Luke is holding a book and some yellow papers while they talk. Sometimes the sheets are on top of the book, and sometimes they are underneath the book.
Continuity mistake: During the opening scene in the cafe, Roz is picking up and putting down her coffee & muffin, but all shots from behind show her holding the coffee.
A Word to the Wiseguy - S3-E15
Continuity mistake: The guy Niles and Frasier meet at the Cafe puts his coffee cup down twice between shots, after he has made the phone call and before he leaves. (00:09:20)
Goodnight, Seattle: Part 1 - S11-E23
Continuity mistake: (This is for "Goodnight Seattle.") When Eddie is eating the pate with the ring in it, in the wide shot we see that he's finished all the food and is licking the plate clean. It then cuts to a closeup, and the plate is suddenly full of food. Back to the wide shot, and he's licking a clean plate again.
Flour Child - S2-E4
Continuity mistake: Near the beginning of the show, Roz takes a large get well card into Frasier's booth - she has some papers as well, which are on top of the card. She lowers the card and the next shot shows the papers are under the card, with no time for changes in position.
Continuity mistake: When Frasier prepares to leave the gay bar, he puts his sherry glass on the bar and pulls back - but the next shot shows him pulling back from the bar again.
Frasier's Imaginary Friend - S5-E1
Continuity mistake: When Marty does his exercises, Eddie watches from the recliner and his bottom is just about in the center of the seat, but as Daphne heads to the door, his posterior is much closer to the arm of the chair, even though he never moved.
Continuity mistake: Blaine sticks the pin in his leg and doesn't remove it, yet after a few shots it's gone.
Suggested correction: The pin is present until Daphne removes it, but in each shot the pin is rotated without anyone touching it. In some shots, it is difficult to see because it is longways on, but it is there.
Where Every Bloke Knows Your Name - S5-E10
Continuity mistake: When Marty, Roz, and Marty's friends start playing poker, one card is dealt out, but a couple of seconds later, the card in front of each person is gone, and the "first" card is dealt again.
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: 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.
Legal Tender Love and Care - S8-E6
Continuity mistake: Niles and Daphne are in the elevator talking about Donny. Daphne has her hands on top of her purse with her fingers laced together. Niles puts his hand over hers but in the next shot his hand is on her wrist and she has her hand against her jacket's lapel.
Continuity mistake: Niles, Frasier, Marty, and Daphne are at Niles' apartment and they have just found out Maris killed her lover. Niles' overcoat is on a chair behind the couch. He decides to go the police station, tells Daphne to stay put, and heads towards the hall on the left. In the next shot he is carrying his coat and heading out the front door with Marty - there just wasn't enough time for him to have got over to his coat and back to the door.
How to Bury a Millionaire - S6-E7
Continuity mistake: Frasier and Niles are at the Shangri-La, looking at an apartment for Niles. While they are standing in front of the closet, sometimes the door is open (revealing the former tenant's clothes inside) and sometimes it is shut.
Continuity mistake: Right at the start when Frasier is talking to Niles in the furniture shop, at one point he says "Don't you hear that," and holds his hand in a fist. The shot cuts instantly to Niles and you can see his hand is now about a foot higher and his palm is suddenly open.
