@r Parodies do not require copyright permission as long as you don't do anything remotely to do with profit - too bad some copyright holder sometimes has the power to screw you over.

Rather than a license, for parodies all you can really do is write a disclaimer pointing out that the artwork is not profit related and that others may share it on and continue the parody.


You can license your "original" artworks just fine mind you - I like the GNU so much; https://irasuto.freesoftwareextremist.com/8e585e23.html the possibility of a proprietary version pains me to no end.
