In 1996, “The Simpsons” did a “Treehouse of Horror” episode featuring Bill Clinton running against Bob Dole. Halfway through the episode, during a presidential debate, Homer Simpson reveals that both candidates are “hideous space reptiles,” complete with dripping fangs, tentacles and one eye each: Kodos and Kang. The crowd screams in shock and horror. Then one of the aliens, Kodos, speaks: “It’s true; we are aliens. But what are you going to do about it? It’s a two-party system. You have to vote for one of us.” The crowd mutters in stunned agreement.
