I don't think this one went a whole season. It was a comedy about a mental institution. Probably wouldn't pass the PC police today.
One of the characters was an old man who could do this funny dancing. I think he also had parts in Hot L Baltimore.
There was another character who was a big fat guy with black curly hair and a bushy mustache. At the beginning of one episode, he was all sweaty from exercising, and some non-crazy female character asked if she could hug him and he reluctantly said OK. It was apparently a therapeutic thing she liked to do with this guy. As if he wouldn't want to hug her and a lot more every chance he got, and as if she really wanted to hug a big sweaty guy.
And that's about all I can remember!
