Corrected entry: Lisa is singing "One (Is the Loneliest Number)" and looks up the composer to find out that he "died of a heart attack suffered on Valentine's Day." Although Harry Nilsson DID suffer a massive heart attack on 14 Feb 1993, he didn't die of heart disease until 15 Jan 1994.Captain Defenestrator
Corrected entry: When Homer and Marge find Mrs. Bellamy's body, the body is shown to be neatly placed on the ground with Bellamy lying on her back. Homer then lifts up the body and it is shown that there is a pair of scissors stuck in her back. If scissors were stabbed in her back, then this means it wouldn't be possible for the body to be neatly placed on the floor lying on her back, as the scissors would cause the body to push upwards.
Corrected entry: When Smithers realises that he shot Jasper, instead of Mr. Burns, he mentions that he left the meeting early in order to watch Pardon My Zinger. However, in the previous episode, you see him walk out of the meeting with everyone else, very slowly.
