I actually read this short story on the same day I saw the new (2012) movie. It is a silly story, makes you laugh at the end. Two days previous to that, I saw the Arnold version of the movie based on this book.
If Arnold's version is based on this story, then the 2012 version would at best be "inspired by" Arnolds version. Anyway, that is enough about the movies, they are just fresh on my mind as I just watched them.
The story is fun, a review seems kind of pointless since the entire story is less than 30 pages. Go ahead and read it. It isn't the best PKD by any standard, but it will fill a subway ride. I can't really imagine writing any more about this, so I will stop now.
