I'm old enough to remember Art Fleming as host, Don Pardo as announcer. Back then, an undefeated left after five shows. Wish they'd limit it to ten. They also kept all their money, so it made 'Final Jeopardy' a bit more interesting on wagers ("Should I gamble it all and possibly lose it all with the chance to win, or be safe and take home what I've earned?") Then again, each 'answer' was worth 10x less back then.
It took me a long time to get used to Alex, having watched him host one game show called 'High Rollers'. When the time comes, no one will be able to fill his shoes, but the show definitely should go on. Didn't realize that Johnny Gilbert has worked with Alex since Day One.
I love trivia, and though I'm watching the screen blankly quite often while my wife is on a roll, I more than hold my own often enough with a bit of luck or sifting through a clue. We love to raise both arms when we're correct and no contestants answers, (twice with an incorrect w/no answer, etc), especially when it is 'Final Jeopardy'.
A pet peeve of ours is how overly finicky they are at times, which we call their 'Sgt. Pepper' moments (an incorrect final question, as it was required to write the entire name of the album for the correct response

)
I'm guessing April 20th will be the first televised without an audience. They did a few weeks worth that way before stopping production a few weeks back.
btw...thanks for the youtube link for the 'Cheers' episode. Now my wife knows what I've referred to often. Wish the whole episode was available.
