It's not really science fiction, but I like this story, by Mike Resnick, the world's most decorated short sf author.
I mention it today because the crew at The Sci Phi Show deserve a shout out for putting together an audio presentation of it. Personally I'm not sure the voice effects add anything to it, but there are versions available with and without the effects available for download here.
I definitely recommend checking it out. It'a a worthwhile way to spend 7 minutes 59 seconds anyway.
