Wow. Do you mind if I ask how this is possible?
I think that’s exactly the point, that we are supposed to ask. Not know, just ask.
One episode of “Father Ted” had a pre-title sequence consisting of the three priests rushing for the sofa and turning on the TV to watch their favourite show, “Father Ben”. 
Ah But: the writing process itself is strangely pointless sometimes, no?
You should really get the Borges story, but the gist of it is that it was written by someone present-day (well, 19something ish when Borges wrote his story). Wheras a lot of Cervantes writing is just late-Renaissance empty flourishes of rhetoric, the words of the modern writer of Don Quixote are full of intentional and thought-provoking meaning.
That’s Borges’ assessment, not mine. I believe he meant it as a parody of literary criticism.
Anyway, Menard decides to write Quixote, not by simply copying it, and not by re-enacting the life of Cervantes in order to start the work with the same body of personal experiences, but by basing it entirely on his own personal outlook. And his result turns out to be an exact duplicate of the original. Borges then discusses how this work is so much richer than the original based on… well… I don’t really know, but it’s an interesting read and nothing by Borges is more than 15 pages long, so go check it out.
And having gone home and checked my bookshelves, my original post was wrong. The Stanislaw Lem book of reviews of fictional books was not Mortal Engines but A Perfect Vacuum.
According to the “Behind the Laughter” episode, the entire “The Simpsons” series has been metafictional.
TV series that were shown to be dreams by one of the characters: Dallas, St. Elsewhere, the final season of Roseanne, Newhart … I must be missing a few, got any others?
In Ian MacEwan’s Atonement…
…we find out in the fourth section that the three previous sections are actually a novel written by one of the main characters, based on her own life, and she’s sufficiently changed the facts enough that they could be considered a work of fiction.
Pat Murphy’s Max Merriwell/Mary Maxwell novels:
There and Back Again by Max Merriwell (a pastiche of The Hobbit)
*Wild Angel * by Mary Maxwell (a pastiche of Tarzan – Mary Maxwell is Max’s Merriwell’s pseudonym)
Adventures in Time and Space with Max Merriwell by Pat Murphy
There is reference in Murphy’s “Adventures in Time and Space with Max Merriwell” to Mary Maxwell’s novel Here Be Dragons. There may be additional mentions of other Max Merriwell and Mary Maxwell novels in the book, too.
The correct forum code used to enclose any reference to Vogon poetry is not [/nitpick] – use [/nosepick] instead.
