I actually know someone who works on the show. I feel bad for him.
What a dumbass move by Roseanne. How can you be her age and not realize that a comment like that will get you fired and ostracized?
Personally I have always felt that comedians deserve extra leeway because otherwise they'll be afraid to tell jokes about pretty much everything, but even they have to have boundaries -- especially when they have a lot to lose like Roseanne did here.
I guess I'll be hearing her doing stupid timeshare infomercials while driving to Vegas again.
