This was quite obviously a parody which is protected speech in the US. There is no ambiguity on this, the creation was not some pure AI generation, it was output based on the parameters set by the Dudesy guys, one of whom is well known comedian Will Sasso of MadTV fame.

People don't seem interested in thinkng beyond a knee jerk reaction against anything labeled AI.
