it takes a lot of perseverance to be a terrible artist. you would have to have the mindset of Ed Wood, Yoshiteru Sato, or Seltzer and Friedberg: consistently never make a good piece of art, not even by accident.
but they're not trying to make bad art on purpose. they're just bad artists. what if, however, you DID make bad art on purpose?

and we just had a good time being silly! creating bad art on purpose is both fun and funny. i would not, in good faith, sell it at art shows or submit it to art contests, but some days, you just have to not take everything so seriously. and creating bad art on purpose could be a good stepping stone in eventually creating good art on purpose, as long as you're not Ed Wood. ;) as they say:
