joke about the status quo

ok.
there was this movie
a really long time ago that i want to say was based on a stephen king novel even though i don't think that's true
but anyway,
it was about these three people
who are the only survivors of a hideous apocalyptic nuclear explosion
and they walk across the whole country, town to town,
in search of anyone else who might have lived.
one of the main characters, i think, was a little mentally disabled
and he thought em oh oh en spelled every word known to him in the english language.
i feel like him. right now i am under the misapprehension that
all of my questions have the same answer.
