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: 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.
