I was watching the Addams Family again tonight and I noticed something that bothered me.
One of the reasons suggested for Fester leaving originally was that he and Gomez were fighting over those Siamese twin chicks. But later Gomez is talking to Morticia and talks about how he met her and proposed to her that same night. Therefore Morticia and Gomez must have met after Fester disappeared because otherwise the fight over the twins would have been moot. How then does Morticia know Fester? A few times in the movie she talks about how he used to be, but she couldn't have known him then.
