New this month Revealing mistake: At court, as Homer is walking towards Alec Baldwin, Kim Basinger and Ron Howard, Bart is in the background sitting with the rest of the Simpsons, but his head is missing from his body. His head then reappears back on his body after about 2 seconds.
New this month Factual error: 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.
Continuity mistake: Lewis changes from black to yellow when Milhouse dares Bart to pull Santa's beard off.
Revealing mistake: After Homer brings Santa's Little Helper home, Homer and Marge hug, and if you look behind them, the background is upside down. There is a picture hanging upside down, and there is a lamp which seems to be hanging from the ceiling. Then in the next shot, the background is normal.
