I thought that "Mork and Mindy" was laugh-out-loud hilarious in Season 1 only.* For some oddball reason, the grandma was written out, Conrad Janis got the boot, and they did a lot of scenes from a pizza place with two new actors I had never heard of. For me, that was the jump-the-shark moment. I never bothered watching after that, even though Janis returned.
I loved Winters too, but I don't think that anything could have saved that show from Season 2 onward.
[*Edit: I will say that fish-out-of-water sitcoms basically are good for only a year or two. I loved "The Beverly Hillbillies" Seasons 1-3; but once they get used to city life, it's not funny anymore to me. How it ran 9 years was beyond me.]
