Oafish bumpkin of a husband, the wise and understanding wife always coming to the rescue.
I don't think the Munsters is about the wife rescuing the husband. The humor is often about the family thinking they are normal, and the reaction they get from interacting with actual normal people. None of the characters are "wise" they all misunderstand the basic nature of what a normal family looks and acts like and fail to realize they are scaring normal people.
MwC was definitely the oafish husband, again with the childish schemes, much like Ralph in the Honeymooners. It's just a raunchy version of the Honeymooners.
ILL is a rare exception - a reverse Honeymooners.
P.S. I still enjoy watching these shows. Especially the Munsters. Herman always makes me laugh.
The Munsters... well, I think I've seen a few episodes. I don't recall the wife (Lily) doing much in the episodes I watched, to be honest. I did see the recent Munsters movie, and Herman is both the cause and solution to their problems, Lily doesn't really do much from what I recall, if she has a comedic premise it's the ridiculousness of her falling for Herman.
