she was in line to take over for johnny as his permanent guest host or take over for him when he retired. i think he got pissed at her when she started yapping about it publicly or appeared on another talk show, something like that, and he pulled the rug out from under her.
in her heyday she was brilliant, sharp, witty, and clever. in her old age she just sounded bitter. it wasn't fun to watch her any more, at least it wasn't for me.
