As Trihs points out, TMNT were at first a nearly line for line parody of Frank Miller’s Daredevil, where Daredevil became a ninja all of a sudden and Elektra made her debut.

Our Topeka Symphony has done two programs of classical music used as cartoon soundtrack material. They also had slides and clips of the cartoons themselves.
Dr. Strangelove was a reworking of a book called Red Alert. The book was serious, rather than satirical, so it could be said that the film was a parody of its source.
One could call Dr. Strangelove a twisted version of Red Alert. Peter George, who wrote Red Alert under a pen name, is credited for the novelization. I’d almost consider Dr. Strangelove a MSTIEing of Red Alert more than a parody of the genre.

Blazing Saddles is of course a parody of Destry Rides Again
