Like Remember WENN, one the great little-known shows. But it’s an hour-long drama with comic touches rather than a comedy. Its seasons parallel Hamlet, Macbeth, and King Lear after all.
I loved this show and almost added it to the thread. But I thought his advertising coworkers were pretty stupid. One bit I loved was when his wife made up a lover, and she made him half-Scottish and half_Hungarian which is essentially my ethnic makeup.
Based on the books by E.F. Benson. Very prolific gent. He also wrote a wildly popular (at the time) book called Dodo and two sequels. It was interesting, but it had a rather devastating final line. I appreciated it more for that than the rest of the book.

Yep, absolutely. But only one season. Too smart.
I liked Frasier, but it did sometimes fall into the “humorous misunderstanding” trope, especially in the later seasons. That itself would violate the OP’s criteria.
The Vicar of Dibley.
I’m currently re-watching Scrubs. It’s a smart comedy with good acting and creative directing. What could have been uni-dimensional characters are nicely fleshed out throughout the series. And Neil Flynn (the janitor) never fails to crack me up.
Yes, the only “stupid” is the jock horndog surgeon, and even so, he is good at being a surgeon.
This might not count since it’s an entirely different type of comedy than a sitcom, but would you consider a game show?
8 Out Of 10 Cats Does Countdown. The game show aspect is just sort of nonchalantly followed to segue from going off on one tangent to going off on the next as it’s really more of a panel show. Watching 7+ comedians going back and forth in real time is a good show in how witty some of these people can be.
Along a similar line of 7 comedians making jokes in real time for 90 minutes masquerading as a game show is the Big Fat Quiz. In fact, it’s the same host and a lot of overlap in the guests.
The Todd objectifies women in an over the top manner, but other than than, I’m not sure if I’d classify him as stupid.
Doug, on the other hand, Doug was their Screech.
I nominate The Many Loves of Dobie Gillis to the list of smart comedies. I always felt this show was ahead of it’s time for a late ‘50’s sitcom. Breaking the 4th wall was unique for sitcoms of that era. It had surprisingly mature dialogue for a show focusing on teenagers and their relationships with peers, parents and authority figures (mostly teachers). Bob Denver’s Maynard G. Krebs wasn’t stupid (unlike Gilligan who he played later), he was just a laid back, jazz lovin’ beatnik. Funny show, clever writing, well-acted.
If the OP allows non-sitcom smart comedies, I nominate Your Show of Shows. Sketch comedy at its finest. Great comedy troupe, stellar writers, timeless humor.
Going back several years, I’d suggest Pearl. It starred Rhea Perlman and Malcolm McDowell as a working class woman who went to college and locked horns with a snobbish professor. Both had their own kind of smarts and eventually developed a grudging respect for each other.
So…basically Educating Rita?
ETA: Just looked up the Wiki page for that. This phrase is hilarious all on its own:
Ah yes - the prestigious Swindon University.
In American terms, this is like talking about the well-known Ivy League school The University of Peoria.
I liked that show, but it was a one season one, wasn’t it?
Also had Carol Kane who often stole the show.
A young Lucy Liu & Kevin Corrigan (Professor Professorson of Community)
Oh, right. I missed that in the OP. It was indeed a single season.
Agree. Clever and funny.
Sounds like an Americanized version of Educating Rita.
Should have read one.more.post.
How about Brooklyn 99? It’s a show about cops, all of whom are super-smart in their own quirky weird ways. There are rare episodes that hinge on misunderstandings, but they’re not as dumb as thinking a goldfish is a person. It’s got some really intelligent writing.
There is a lot of cringe humor in that show. I think it goes against what Dr. D was looking for in the OP.
I used to love that show. “You rang?”
Too many great, smart comedies got canceled early. 
I think the American public really doesn’t like smart comedies.
Derry Girls is excellent. I have a pretty low tolerance for cringey humor and find it very watchable (aside: I find it weird I can watch violent or scary show without my brain thinking “oh no this is actually happen, be scared!” but I can’t do that with an embarrassing cringey comedy show. My brain is like “Oh this embarrassing thing is actually happening! Be embarrassed!”)
The older Irish (from Ireland not Northern Ireland) show Father Ted is absolutely amazing though the much of the humor is based on the fact Father Dougal is dumb, so I guess doesn’t count.
If films count, and you like political humor I just saw Vice and thought it was excellent. It does feature George W Bush so may be disqualified on the same count (though his stupidity is not played for laughs like Kramer’s IIRC)
