Christmas Vacation (1989)

"National Lampoon's Christmas Vacation" is the beloved holiday comedy following the Griswold family as their attempt at a perfect Christmas spirals into chaos. Amid the sled mishaps and family squabbles, Nicolette Scorsese turns up as the object of Clark's daydreams, delivering the film's lone flash of skin in a fantasy sequence that's become a fan favorite. The archive holds just 1 scene from the movie, but it's the kind of brief, memorable aside that keeps this Christmas classic in rotation on the site long after the tree comes down.
