Continuity mistake: At the beginning of the show, Niles, Frasier and Daphne are at Cafe Nervosa. Daphne is standing up talking to Eric the server and Niles gets agitated, and spills sugar everywhere. Eric throws down a dish towel so they can clean it up. The dish towel appears and disappears several times during the scene.
Continuity mistake: When Luke and Frasier are talking in the restaurant, and Frasier asks, "So Luke, you're a boat enthusiast?", his forearm is resting on the table. When the shot cuts back to him, only his hand is resting on the table, with no time for him to change position.
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.
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.
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. Suddenly in one shot it has moved to the left, near Frasier. Later in the scene it has switched sides again.
Continuity mistake: Near the end of the show, Roz and Frasier are at the radio station, in his booth. There is a clipboard lying on the console to the left. Roz goes to her booth (without the clipboard) and Bulldog bursts through the door on the left. The clipboard has disappeared. Shortly afterwards Roz goes back into Frasier's booth and the clipboard is back where it was.
Continuity mistake: Frasier and Roz are in the kitchen talking, and Frasier says "over thinking things can spoil anything", and we can see Roz lifting a glass of water in her left hand. The shot changes and she now has her right hand up to her mouth and a split second later there is a sticky bun in that hand.
