I recently picked up a copy of Cracked Magazine issue 301 (September 1995) which has a lengthy spoof of Batman Forever.
For those that don't know, Cracked was a US humour magazine that ran between 1958 and 2007 before moving online (and turning into more trivia and list-based content - think Buzzfeed before Buzzfeed). Each issue was filled with spoof and caricatures of various news events, TV and film.
If you want to read this, I've uploaded all the relevant pages to a PDF here on the Internet Archive.
It's a fascinating read as I imagine it was written before the film came out so the writer - Lou Silverstone - probably only had the clips from the trailer and any news stories about the film to work from. As such it only loosely follows the plot of the film.
They also have Edward Nygma's character dubbed Lysol Hellendorf - a play on his name from the original Batchler's script Lyle Heckendorf. I don't know if that means Lou managed to get a copy of the early script to work from but it's kind of fascinating.
There's some really interesting stuff in here - including lots of jokes that went right over my head. I'll probably do a quick video on it at some point this year.
If you haven't seen it already, there was also a Batman Forever spoof in Mad magazine (Cracked's rival) that you can read as a PDF here.
