I understand with over 700 episodes at this point in the series, no matter what the episode is, it will resemble a previous episode. So it is another into the Future for Lisa. Sounds familiar, right? Well, Lisa gets to experience the future and this time it is about how she never got over her school girl crush on Nelson Muntz. They fill the story with a bit with references to Milhouse's pleas for recognition as her suitor. Probably just another filler is a droll reference to Ronald Reagan and Abraham Lincoln as being more than strange political bedfellows. Must be great to congratulate yourself on your educated superiority with misusing a forum for snarky political diatribe. Oh, well.
