Corrected entry: Bill Daily plays a bumbling politician in this episode, where he comes over to Mary's apartment on a Sunday evening. It has been definitely established that this is Sunday. When he shows up, he is wearing a kippah (yarmulke), and Rhoda (who is Jewish) comments, "I knew there was something I liked about you," meaning she is assuming he is Jewish. Then he takes the kippah off, and calls it a "beanie." He isn't Jewish. He says he has just been to a Bar Mitzvah. The problem is that Bar Mitzvah services don't take place on Sundays; Bar Mitzvah services are nearly always on Saturday. To be on a Sunday, the Sunday would have to be a High Holy Day (three days out of the year). Even then it's not usually done, and would be in the morning anyway. This episode aired at the end of the season, not the beginning, when the High Holy Days take place. To a gentile, this probably seems pretty obscure, but it bugs me every time I see this episode.

Starring: Edward Asner, Mary Tyler Moore, Gavin MacLeod, Ted Knight
Genres: Comedy
Continuity mistake: This episode and scene has been referenced already but contains another error. In the scene where Lou is recalling the first time he met Mary, he claims Mary had asked for a job as an assistant producer when in fact he gave her the job because it paid less than the secretary job she wanted.
Ted Baxter: It's actually tomorrow in Tokyo. Do you realise that there are people alive here in Minneapolis who are already dead in Tokyo?
Trivia: Mary Tyler Moore was very concerned about the fashion appearing on the show, if the hemline changed in Paris then a scene would be shot over again with the hemline of the dress/skirt changed accordingly.
Correction: The scene that you're referring to actually takes place on Saturday evening. The meeting in Mary's apartment was to prepare for a show that was filming on Sunday. On Friday, Mary was reprimanded for taking a 55 minute lunch without having a guest for Sunday's show. Mary met the politician and his staff members on a Friday. And on that Friday, one of the staff members invited the other staff member over for dinner that night. At Mary's apartment on Saturday, she thanked her for dinner "last night. " The next scene shows the politician filming the show with Ted Baxter on Sunday as scheduled.
