Batman The Killing Joke comic book from DC Comics
During the 1980's to early 1990's, Alan Moore reigned supreme as one of the best writers in comic history (I will still argue with anyone that the 1980's was the best era for comic stories).  The Killing Joke was his Batman story and what a story it was.  Anyone who ever read it will never forget it, especially the joke at the end.
