Question: Why did the Howells, Ginger and Mary Ann have so many changes of clothes with them? It was only a three hour tour.
Answer: I've been binge watching it, and a couple of times trunks with costumes have washed ashore, and in one episode the professor figured out how to make thread for weaving cloth.

Question: How can Andy meet Sergeant Carter here if they met in the pilot episode of Gomer Pyle, USMC?
Answer: There's no indication they were meeting for the first time, in fact they seem to know each other as Sgt. Carter addresses Andy only as "Sheriff". Gomer Pyle just says his two favorite people are "meeting face to face", and obviously in the pilot episode Sgt. Carter wasn't one of Pyle's favorite people yet.
Question: Why would Solo compare the descending elevator to an Eaton's department store, when these only existed in Canada?

Question: Darren was angry at Samantha for getting rid of his favorite coat so, why was he even angrier when he got it back?
Answer: Larry had been telling Darrin what it means psychologically that Samantha gave the coat away. Larry said giving it away meant she's happy being married but if she liked the coat it means she desires to be single and carefree. So when Darrin sees the coat, he immediately thinks Samantha doesn't want to be married and the fact that she twitched it means (in his mind) she wants to be a single, carefree witch again.
Answer: I haven't seen the episode, but generally in the show, Darrin was always suspicious that Samantha always used some kind of witchcraft for any situation (even if she didn't). He probably figured the same thing with the coat while in her possession.
You should watch the episodes in question before giving an answer so you know what you're talking about.
Question: Why do they act so oblivious as to why people are scared of them?
Answer: The comedic gimmick of both "The Munsters" and "The Addams Family" television shows in the 1960s was that both families were convinced they were normal and everyone else they encountered was odd. The Addams Family, for example, thought their "normal" visitors were mentally unbalanced because they always fled the Addams' weird home in panic. That was a running gag throughout the entire Addams Family series, so much so that easily half of nearly every episode was devoted to the predictably terrified reactions of their visitors (always accompanied by identical canned laughter). Meanwhile, in the Munsters' universe, the family thought "normal" people were physically deformed and even quite hideous. For example, the Munsters believed that their beautiful niece, Marilyn, was socially handicapped by her ugliness (the exact opposite of the truth); and, in the episode "Just Another Pretty Face" (S2E17), when Herman Munster was temporarily transformed into a "normal" person, his entire family found him utterly repulsive. The family's hidden revulsion to "normal" people was the running gag of The Munsters.
Question: Ted (Lurch) Cassidy was a total of six feet nine inches tall. A number of times, especially in Season 2 Episode 6, "Cousin Itt's Problem", it seems the top of his head barely clears to top of the door jamb. Were the doors seven feet tall back then?
Answer: Bob Denver answered this when he was on a talk show hosted by Pat Sajak. He said they were going to write into an episode where the castaways found all these clothes, but it got too complicated, so he said, they decided, "who cares, it's only a TV show," and forgot about it. So the writers and actors even asked this, they just never bothered to address it.
