Producers of "The Simpsons" wanted to make sure not many people knew who did it. David Silverman was the only animator who knew it while the episode was being made. Wes Archer (director of the second part) did not know that Maggie shot Mr. Burns. Silver and Archer did not work on the animation of the ending until summer in 1995. They made other animators do smaller work so that they did not know who did it. In the table-read (when the show's staff read the script) of the episode, they did not read the ending. Parts of the animation had to be made again so that it got the clues to the mystery. Oakley and Weinstein were not sure if Maggie should have done it, so they made the ending seem as if Maggie may not have shot Mr. Burns accidentally.
