I recently read "Bears Discover Fire" by Terry Bisson. An odd story but I really liked it.
It won the 1991 Hugo Award, Nebula Award, Theodore Sturgeon Award, SF Chronicle Reader Award, Locus Award and Asimov’s Reader Award. The story is just what it says in the title.
I also read Bisson's The Left Left Behind which satirizes the Left Behind books and postulates that the world might possibly be a better place after the Rapture.
