Continuity mistake: The large spoon and fork in Frank and Marie's kitchen change positions, right to left, and up and down. In some episodes the fork is on the right, and in others it is on the left. In other episodes, the fork is higher or lower than the spoon. At other times, the spoon and fork seem to be larger than at other times. It is obvious when she removes one of the utensils that they have never been moved - The Wallpaper underneath is a different shade from fading. If these were moved at subsequent times in the supposed feud, the difference in wallpaper fading would be seen.
Continuity mistake: In the kitchen scene Ray gives Debra a card that says "I Love You." The twins are seated in high chairs. Debra places the card on the table. At the end of the scene Ray picks it up off the high chair to give to Debra. Additionally, the twins are not in the chairs. (00:09:25)
