Continuity mistake: In the scene where Carla is sitting at a table in the bar, dressed as the new Madame LaCarla and is voicing her doubts about being the new Madame, you can see that Carla is only wearing ONE earring. (left one). In other scenes she is wearing both earrings.
Continuity mistake: Just before they reveal the answers of Final Jeopardy, they take a wide shot, and Cliff's question (Who are 3 people who have never been in my kitchen) is already revealed. But when they take a tight shot and ask Cliff to reveal his question, it is covered up.
Continuity mistake: Sam, Norm, and Woody are helping Rebecca move into Robin Colcord's house. When a curious Norm opens a bedroom door, the wall is bare. The shot cuts to Rebecca then back to Norm, but now there is a desk with flowers and a vase on it, plus a picture hanging on the wall.
