Corrected entry: In this episode Roz is supposed to be pregnant. She found out two episodes before that she was going to have a baby. If so, then why is she drinking alcohol with Frasier and Niles? If she's pregnant, she shouldn't be drinking alcohol. You could see her drinking at two different times what appeared to be some kind of whiskey at one point, and then some kind of wine later on.
The Life of the Party - S5-E22
Corrected entry: When Roz is in labor at the hospital, Daphne arrives and tells the others that she came as soon as she heard. But she is saying this to Frasier, Niles, and Martin - the only three mutual friends that she shares with Roz. Nobody else could have told her to come.
Correction: First off, it is established that Daphne and Roz have a friendship of their own and, while the audience may never see it, there is nothing to say that they do not have mutual friends. But even if they don't have mutual friends, Daphne indicates that she received a message from her date (where he made up an excuse for standing her up). It is conceivable that Frasier, Niles or Martin left a message for Daphne (off screen) and she was letting them know that she got there as soon as she received the message (since she was on a date). At worse, it was a poor choice of words but it is not a mistake.
Corrected entry: This episode shows Niles wants to organise a anniversary dinner for him and Maris, but back in season 4 episode 22 he went through hoops to sign divorce papers and in the end he did in fact sign the papers. So this anniversary dinner seems odd and out of place for the situation currently going on with them both - why would he organise a anniversary dinner for a woman he is divorcing?
Correction: At the end of s04e22, Maris calls Niles and says the divorce papers were a bluff and by signing them it threw her off, so she was willing to go to couples counseling. In later episodes it's revealed counseling was going well. (And just because he signed the papers doesn't mean they became officially divorced).
Corrected entry: Frasier and Niles get stuck on the Monorail and have to go back to the previous station because of an electrical failure up ahead. Why then, does a train zoom past them going in the direction they wanted to go?
Correction: Clearly, the train that passes is on a different rail to them, and it is their rail that has the electrical problem.
Correction: "Shouldn't" isn't a legitimate mistake. Plenty of women drink small quantities of alcohol while pregnant with no ill effects, despite recommendations against it.
