the staff actually have. Despite having already left the show by the time this episode was made, a portrait of former producer Sam Simon was drawn by Simon himself after he did not like the original joke for him, which was a "No Photo Available" disclaimer. One of the clips shown in the episode comes from the season four episode "Marge Gets a Job", in which Smithers has a dream that he is sleeping and Mr. Burns flies through a window into his room. The sequence shows Burns flying towards a happy-looking Smithers. The original clip went on for a few seconds longer, but had to be trimmed down in order to remove portions that showed "Mr. Burns land[ing] in a particular position on Smithers' anatomy". There were also issues with "the lump in his bed", which the animators said they had drawn as his knee, but the censors had mistakenly believed was an erection. A deleted scene from the season five episode "Burns' Heir" is also shown, in which a robotic Richard Simmons dances outside Burns's mansion to the 1976 song "(Shake, Shake, Shake) Shake Your Booty". It was cut from "Burns' Heir" because the writers did not think it was funny, nor did it do well with a test audience, although Oakley thought the animation was terrific. To the production staff's surprise, the scene would make the audience "erupt with laughter" when screened at animation conventions and college presentations, so they decided to insert it in this episode. The montage of nude scenes over the ending credits includes the original animation of Homer and Marge snuggling from "Grampa vs. Sexual Inadequacy", which was reanimated in that episode after Fox censors thought it was too explicit. Due to the amount of interest in the ending of the "Who Shot Mr. Burns?" episode, David Mirkin wrote several "terrible endings" and recorded several alternate endings with Harry Shearer serving as the only voice actor. Mirkin's original intention was to fool the production staff and also leak the endings to various media outlets; much to his surprise, Mirkin failed to successfully fool the staff. Several endings were animated that showed various characters, such as Barney, Moe, and Apu, shooting Mr. Burns, and were presented as part of this episode.
