What about Mark DeCarlo, of "Studs" fame? He definitely doesn't qualify for "best of all time" status, but he had some terrific sardonic quips for a whacky show which needed the neutralizing effects of his smug nonchalance--he had a firm grasp on the notion that the whole show was just a joke.
I hold Chuck Woolery in high regard--compared to most twerpy game show hosts, Chuck was more of a "man's man," the kind of guy I wish I resembled with excellent manners, a good voice, and a genuine laugh to complement his quick wit.
I'm surprised Pat Sajak is taking it on the chin in this survey--I suppose it's because he's so professional, and, thus, difficult to parody & mock.
Alex Trebek is just annoying. I agree with comedians and other folks who observe that he always acts like he crafted each question from his own grey matter and passive-aggressively condemns the contestants when they respond incorrectly.
