 The episode does not feature any wraparound segments , which are normally used in Treehouse of Horror episodes . The wraparounds had been cut from the previous year 's episode , so the writers did not bother writing one for this episode . " The Thing and I " was written by Ken Keeler , " The Genesis Tub " was written by Dan Greaney and " Citizen Kang " was written by David X. Cohen . Despite the similarities , " The Thing and I " was not based on the plot of Basket Case . " The Genesis Tub " was originally pitched by Cohen and it was later referenced in the South Park episode " Simpsons Already Did It " , when they pointed out that The Simpsons had earlier gotten the idea from the 1962 Twilight Zone episode called " The Little People . " The sequence where tiny spaceships attack Bart in " The Genesis Tub " marks one of the first uses of computers in The Simpsons animation . The computer was used to build models for reference and the animators later retraced it . The 1996 Presidential election occurred a few days after the airing of this episode . According to Cohen , the " Citizen Kang " short violated every rule of The Simpsons as it locked the episode in one time and named specific candidates .
