Help finding "QUIZ SHOW" shory story!!

I read part of a GREAT-sounding short story, it was just a snippet, in a school text. All I remember was the title was "Quiz Show" or "Game Show". Here's more stuff dragged out of my rusty memory...

The Host has got a "Mr. Good Guy" goofy grin, there's Mr. All-America, some ditzy blonde lady (story is kind of a microcosm of American life) and I remember one line, directed to the guy in the middle of all this...

"Who is the fool? THOU ART!"


If anyone can tell me more about this story, an author or something, I'd be so grateful I might not even kill people randomly today, as I usually do on Thursdays.

THANKS ALL!
