As an occurrence, movie, or game etc. attains cult status, commentary often crosses into the realm of complex artistic expression by those who most appreciate it. Although some may see these as comedic, which in fact they are, they also have an element of pop art that reflects the culture that created it. Here are a few examples, YouTube seems to be a natural repository for these, however other sites, such as Encyclopedia Dramatica, showcase these as well. I’m sure these links barely scratch the surface of whats out there, share others if you like, thats how I came across most of these.
