Why you know her: Rivers is a polarizing figure these days due to her career as a take-no-prisoners red carpet commentator, but to pigeonhole her as a mean-spirited plastic surgery nightmare is to completely gloss over the fact that she's a truly groundbreaking figure in her field.
Why she'd be great: Rivers was one of Johnny Carson's go-to talk show guests and filled in for the "Tonight Show" legend numerous times - often to better ratings than what Johnny was pulling in. She then took the helm of her own short-lived late-night talk show on FOX, which unfortunately imploded in spectacular fashion (and was shortly followed by the suicide of her husband Edgar Rosenberg). While the chances of Rivers actually taking the helm of a late-night network show at this stage of her career are essentially non-existent, it's hard to deny that she's more than equipped as a comedian and improviser to handle the gig.
