In our second installment, we continue diving into the holiday classic, Christmas Vacation, starting with the meeting between Clark and the CEO of his company and ending with a spectacular failure lighting up his house. In between, both sets of parents have arrived to spend Christmas with the Griswold's. In an effort to both escape and impress them, Clark resolves to decorate the exterior of his home like never before. The Griswold Effect is alive and well, meaning he will likely fall and crash multiple times, but, as his neighbors realize, will never actually break his own neck. Even sliding off his own roof does more damage to his neighbor's CD player and stereo system than to himself. However, after dragging everyone outside, only to not have the lights work, we see a definite difference between the sets of parents. Ellen's parents mock and deride Clark, actually helping to bring his wife and kids to his defense. On the flipside, Clark's own parents are much more compassionate and we actually end the episode with a nice daddy-daughter moment.
