Mrs. Kravits would be known today as Neighborhood Karen.
One of my favorite lines in the usual script was delivered by Darrin’s boss, Larry Tate. Larry was married to this nagging hypochondriac named Phillis, who had a habit of phoning him every time she felt a ‘sick headache’ which was quite frequently.
When he couldn’t dodge his (attractive) secretary who answered the phone, Larry would listen for a few minutes and wrap the call up with ‘Phillis, take a pill!” then hang up. He knew that’s where she was leading to anyway. Not the most nicest of husband responses, but it was quite funny to my family anyway,
There were TWO Gladys Kravits as well.
Alice Pearce died from ovarian cancer after the first two seasons and was replaced by Sandra Gould.
Phyllis was Darrin’s mother - who did have the sick headache — usually after seeing some witchcraft.
Larry’s wife was Louise (played by 2 different actresses — maybe more)
