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: When Niles and Kit are at Frasier's apartment, Kit does a quick dance with her arms out and tells them Niles is taking her to Euro Disney. A couple of shots later her little purse is back under her arm, even though she had no time to pick it up from the bookcase.
