I walked away from the brainless (and mind-killing) tOOb a long time ago; not sure it's worth even asking on what program she starred, because I have probably never seen it.
Roseanne is an unfunny, hog-fat comedian. Like so many on our TVs, there is no particular reason why she popular (or was it the show independent of her). I can think of many celebs who are simply annoying and rude; somehow, advertisers and viewers think this is great.
If you want to live, you must kill your TV.
