As Jeopardy devotees know, if you're trying to win on the show, the buzzer is all. On any given night, nearly all the contestants know nearly all the answers, so it's just a matter of who masters buzzer rhythm the best.
It is better to remain silent and be thought a fool than to open one's mouth and remove all doubt.
I mean, sometimes... a comedian becomes an actor, and they just don't deliver, because the bottom line of comedy is to be funny, and the bottom line of acting is to be truthful, and they get that mixed up sometimes, or don't even notice that that's the thing.
