Samantha and Darrin get a card from the boy they took in last year for Christmas and have an episode long flashback of the previous year's holiday episode.
Note: repeat of "A Vision of Sugar Plums" (S1E15). The cold open is identical. There is one new scene, after the opening credits, in which Sam and Darrin open and read Michael's card, and go into the flashback. Two short early sequences with the Kravitzes (and which did not feature either Samantha or Darrin) are removed—the rest of the episode is identical to the original.
