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.
Continuity mistake: Carla tosses Rebecca an egg she is supposed to take care of, like a baby, for a $5 wager. The egg bounces off Rebecca's hands and over the bar onto the floor. In the next scene, Lilith and Frasier are walking into the bar and the egg was shown as being smashed on the bar itself. The next cutaway, with Lilith walking by the same spot, has no egg on the bar anymore.
Continuity mistake: After Don leaves the bar, a few minutes later Frasier shouts at him, "Run, Don! Run like the wind!" and Rebecca is left sitting alone at the table crying, but when it cuts to the overhead shot of the bar we see Don is still sitting at the table, even though he left five minutes earlier.
Continuity mistake: When Sam tells everyone it's closing time, he asks Harry how he got into the bar whilst he is playing snooker. He replies and then places a white snooker ball two inches behind a blue ball. There is also a yellow ball about three inches to the right of the blue ball. In the next shot, the yellow ball has suddenly moved a foot away from the blue ball. The yellow ball returns to its original position three inches away from the blue ball in the next shot.
Continuity mistake: At the point Cliff is disputing the fact that he thought his answer was right, on the right-hand side you can see the woman player's, Agnes, score. It says $400. Then in the next shot it changes to $3300. Then in a little bit later it changes back to $400.
