18. And Knight almost walked out of the show
During season three Knight walked into a producer’s office, apparently wailing, “I can’t do it. I can’t play Ted Baxter anymore. Everyone thinks I’m stupid and I’m not.” After a pep talk, however, he decided not to quit the show and was given the odd special episode where Ted Baxter appeared less dim-witted.
17. An unknowing extra appeared in every single episode
The opening sequence of the show accidentally featured an older woman in the distance, looking confused as to why a woman was throwing her hat into the sky. She was Hazel Frederick, a Minnesota local who was shopping when the scene was recorded. And charmingly, when Frederick later attended one of Moore’s book tour events, she was addressed by the TV star as her “co-host.”
16. Mary Richards’ apartment became a tourist attraction
The exterior of Mary Tyler Moore’s character’s home was featured heavily during the first five seasons of the show. As soon as it became successful, in fact, the real owners of the house were swamped with visiting fans arriving in tour buses. So in a bid to discourage further exterior filming for series six, one of the owners, political activist Paula Giese, draped “Impeach Nixon” posters outside. Her tactic worked!
