Under the Dome - Stephen King
He wrote a story a long time ago (I think in
Nightmares and Dreamscapes) about a random finger that appeared out of a guy's sink and haunted him.
He explained that by saying that it's fun to write a storyy with no explanation...just pure screw-with-your-head schtick, for the sake of itself.
It was a good story, I liked it.
But Buick 8 was that 10-page story for 300 pages...it outlived its welcome in my mind.
