Question: Homer travels back in time and causes changes by what he does in the past, like stepping on a bug. I once saw a movie with the same basic plot: some people travel back in time and are told to be careful not to disturb anything, but when they return to their time everything has changed. In the end they discover it was because they stepped on a butterfly. Does anyone know the name of this movie?
Question: In this episode, Sideshow Bob seems to no longer want to kill Bart (shown by his happiness at seeing him near the dam, and later on, saving his life, as well as Lisa's). But in episodes after this e.g. "Funeral for a Fiend" and "The Great Louse Detective", Bob suddenly wants to kill Bart again. What caused him to change his mind after this episode? It can't be because he thinks Bart is responsible for sending him back to jail because in this episode when Bob and Cecil get arrested, Lisa defends Bob and says he had nothing to do with it, and Lou even backs her up by saying that Cecil confessed to the whole thing.
Question: Why do the characters in this show, and other animated shows, always wear the same clothes and have just a few different outfits (ex: Marge's regular green dress and her Sunday dress)? Wouldn't most fans be able to recognize the characters even if they did wear different clothes in each episode?
Question: During this episode we see Bart stay with Flanders while Marge is in labour with Lisa. However Rod and Todd seem to be the same age here that they are in normal episodes. Lisa even babysits them in some episodes despite them obviously being at least 4 or 5 years older than her. Compared to Bart and Lisa, how old are they supposed to be?
Question: I remember an episode where Moe picked up a hitchhiker in his car, then asked the man if he had seen some movie. When the man said no, Moe told him something like "Then this will all be new to you" and then drove down a scary-looking road. Does anyone know what part of what movie he was referring to?
Question: Lisa refuses to appear in the variety comedy show. However, she does relatively "flashy" things in a few other episodes - i.e. participating in a beauty pageant. So I think it's odd that she disagrees with a comedy show. Is there a joke that I am missing?
