Synopsis
In a peaceful town on Christmas, Scratchy runs by a movie theater, and then by Itchy's house, whom he wishes a merry Christmas. Itchy pulls on a string of Christmas lights to slice Scratchy's head off. Itchy begins to torture scratchy by using a Christmas cookie to tear open his body to remove his organs, pull out his eyes with a nutcracker, etc. At this point, Krusty appears, standing in front of the TV screen and explains that he is blocking violent images in the cartoon due to "modern sensitivity". Krusty looks at the cartoon and is shocked by the violence. He then throws a pie at the TV screen to block all the gore.
