Never Live It Down: Ironically, despite Forgiveness being the theme of this episode, some viewers aren't forgiving towards Marge and Homer for punishing Bart. On the other hand, others aren't forgiving towards Bart for making Lisa cry by throwing her centerpiece into the fireplace on purpose.
Nightmare Fuel: Bart's Imagine Spot where his family uses him as a scapegoat while taunting and laughing at him could be considered unsettling for some.
Unintentionally Sympathetic: Bart for the part of the fan base that saw Homer and Marge as being too cruel in their punishment. Even worse when you consider that the rest of the adults never tried to get in between his argument with Lisa until her centerpiece was already destroyed. Despite of this, even if one could ignore Bart destroying Lisa's centerpiece, and pulling mean-spirited pranks and acts in the other episodes, Bart refuses to apologizeand never saw any reason to until after running away. Speaking of which, when he was interviewed by Kent Brockman, Bart openly mocks his family and taunts them out of spite.
Crossing with Skewed Priorities, Bart tries to put the turkey where Lisa's centerpiece is when there is actually implied room for the turkey where Homer is sitting, judging by Homer's eagerness to carve the turkey.
Can also apply to Lisa; Bart is carrying a heavy and hot turkey, and clearly needs to put it down as soon as he can. Lisa could have easily slid her centrepiece to the side so that he had room to.
The Woobie: If there's one thing the fans can agree on, it's that Lisa is definitely one here; she never did anything wrong yet she gets her centerpiece thrashed and blames herself for Bart running away.
