I wrote a short story once about this...
"Kenneth, what is the frequency?" On October 4, 1986, while walking along Park Avenue to his apartment in Manhattan, Dan Rather was attacked and punched from behind by a man who demanded to know "Kenneth, what is the frequency?" while a second assailant chased and beat him."
In my story, Dan Rather is a bad guy from the future who has come back and is posing as a credible news anchor to manipulate America.
The man who confronts him on the street and yells, "Kenneth, what is the frequency?" is the good guy from the future who has come back to find the rogue imposter Dan Rather...to get the proper frequency settings that will save the world from a nuclear holocaust.
I thought it was quite a compelling piece of art. I should revisit it sometime.
