I'm not Mensa and I can't say these are the smartest, but the TV shows I've enjoyed most are:
Barney Miller
Friends
Roseanne (early years)
Fawlty Towers
Absolutely Fabulous
Wow, that's about it. Hm.
You must be really really smart. I was jotting a list as I read this thread and it is almost identical to yours.
I added 'Are You Being Served', did not include 'Friends' and did include Newhart...all of them. Barney Miller is my top TV favorite for the US programming.
