I'd go with MASH from Season 4 on. Never cared for Trapper John. And minus the anti-war rhetoric that popped up from time to time. But overall, probably my favorite sitcom.
On my short list would also be Frasier.
And I grew up with the Cosby show so there's a nostalgic link there.
Jake & the Fatman.
The Equalizer.
Simon & Simon. (Sit ubu, sit. Good dog)
Murder she Wrote.
MacGuyver ain't liver than a, Big Tymer. (some will get it, some won't )
The Fall Guy.
Remington Steele.
Dallas, Dynasty & Falcon's Crest on Friday night with my Granny.
Walker Texas Ranger.
