Grampa's Christmas Origins: Christmas Lights/References

Cultural References

 * The story's being set in 1947 in Roswell is a reference to the 1947.

Trivia

 * The Flanders family are a far-flung clan (as indicated in the Flanders family reunion seen in "Lisa the Vegetarian"), so it's entirely possible for there to be a Ned look-a-like in Roswell in 1947.
