I'm glad someone posted.....I'm a child of the 80s too, and I thought she was a sweetheart.
There's an episode of 'Gimme A Break' where Nell and a half dozen other...uhhh....'roomy' people, are trapped in an elevator going to a Weight Watchers meeting. It's one of the funniest half hours of tv ever.
I always liked her too, but my partner tells a story of a gay cruise he took a few years ago (before he met me), and she was the entertainment. During her performance, she made some derogatory remark or something, people starting booing, she got pissed off, threw the mike down and walked off the stage, never to return.
