regarding the odd eyebrow phenomenon, it may be the result of shaving off her eyebrows and penciling them in. I read about this practice in Platinum Girl (by our Eve) when Jean Harlow started doing it. It gives such an odd, unnatural look, but many hollywood people do it, apparently.
I, personally, would pay to fly widows and orphans of 9/11 to see Joan Rivers perform. I imagine that before she even made it to the “punch-line” of that joke, there’d be a dozen or more of them up there, ripping her throat out. I can’t think of a more appropriate way for her to die.
