George doesn't get near enough credit for what he did on Weakest Link... he had to
•replace a very iconic host that that originated the role, without duplicating her style
•balance the triple act of being a straight game show host who will keep the game moving, being warm enough to get contestants to open up on camera, and being a condescending malapert willing to get down in the mud and really roast them
•read 60-80 questions smoothly and clearly every episode, with no time for retakes
•make funny ad-libs about contestants' lame excuses, without depending on a producer or cue cards or an IFB in his ear
It is not an easy role, especially for somebody who was relatively unknown at the time, but he absolutely held his own. I still think that's some of his best work. He hit just the right mix & supplanted Anne Robinson in my mind.
From what I've heard, there was supposedly an episode where he took a direct potshot at ATGS (the direct forerunner to The Game Show Forum), and it went over about as well as expected.
I think I remember the story was that the producer was unhappy that ATGS was lambasting his show, so he made it a recurring bit on the show to call out the site by name mocking in as many ways as possible ("our consolation prize: hanging out with the other losers at alt.tv.game-shows") & do thinly veiled jabs at specific posters & comments. Which only made ATGS more irate, which only made the show more acidic, etc.
Luckily, everybody learned after that incident and nobody ever overreacted about/on a game show message board again.
