Continuity mistake: The mashed potatoes in the serving bowl vary in amount and appearance (flat or peaked) as it is passed around the table. Suddenly, the bowl is about half full, but is full again near the end of the "food fight." (00:28:05 - 00:28:52)
Other mistake: The outdoor newspaper dispenser has "The Mistleto Post" written on the side, misspelling "Mistletoe". (00:37:18)
