Continuity mistake: At the end of the show. Roz is sitting at a table with Bulldog. She picks up the stuffed dog he gave her and chases him to the door, leaving her purse behind. She then goes to the back, probably the Lady's Room. When she returns, she brings her purse with her, even though she left it on the table.
Continuity mistake: Frasier goes into his booth and puts down the magazine featuring Madeline with the page open. Bulldog comes in and looks at the page, and says how attractive she is. But it is definitely not the same page that Frasier had been looking at a couple of shots before.
Continuity mistake: Eddie is sitting in Martin's chair while Daphne feeds him pate from a plate on Marty's table. At the same time she is scratching his ears. The shot changes, and without enough time for this to have happened naturally, Eddie is lying on the chair and Daphne has the plate in her hand.
Continuity mistake: Martin goes out to a baseball game with a famous writer that Frasier and Niles admire. While he is out, they read one of his books he accidentally left behind. When the author returns, he ends up holding the pages of the book in his hand, whilst standing in front of the fireplace. In one shot he is holding them in his left hand, but when the view cuts to another angle, he has them in his right hand. This occurs just before he goes outside to throw the pages off the balcony.
Continuity mistake: Niles is at Frasier's apartment, visiting with Marty. He takes some crackers out of his black fanny pack and puts the fanny pack behind him. We see it there when he stands up but there is a shot where there is nothing on the couch behind him. It then goes back to showing the fanny pack.
