Another question: Which game show hosts ever hosted Saturday Night Live? It struck me while seeing Alec Baldwin. Drew did. Milton Berle hosted Jackpot Bowling and the SNL Lorne Michaels has never let be rerun.
Just going off the exhuastive Wikipedia list of hosts...

Harry Anderson-pilot for a
What's My Line? revival in 2000, hosted SNL several times in the 80's
