The Final Jeopardy! questions seem to be, by design, things you can't know. And so it's not about who knows them, but who can figure them out in thirty seconds.
In fiction, plenty do the job of conveying information, rousing suspense, painting characters, enabling them to speak. But only certain sentences breathe and shift about, like live matter in soil.
I compare it to being in a car accident. There's so much adrenaline rushing through you that you remember being in the accident but you don't remember any of the details.
