Of all the available hosts the producers could choose, why oh why would they choose Mayim Bialik? A has been from a now gone TV series (I think I watched a couple episodes, but found the whole concept completely unrealistic so never went back) obviously she needed a job? All of us should be thankful she didn't end up promoting Medicare scams like has been actors and comedians Joe Namath and Jimmy Walker! My preference would be for her to go home and enjoy her savings.
Now we have Ken Jennings, who would absolutely, positively make an outstanding permanent Jeopardy host, assuming he us done with The Chase.
