In the movie National Lampoon’s Christmas Vacation, Chevy Chase plays Clark “Sparky” Griswold, who decorates his home with 25,000 Christmas lights. Comedy ensues as he tirelessly works to find the one burnt out bulb that’s prohibiting any of lights from coming on. The lights go live, he’s electrocuted (but survives) and the local power station has to kick into high gear to supply the power. The 1989 classic comedy is good fun and airs at this time of year.
