Clark Griswold was working on a non-nutritive cereal varnish and his boss demanded a brief summary he needed by the end of the day. Clark thanked him for the Christmas card at which point his boss looked at one of his lackeys and was informed that the card was a "corporate card". His boss walked by after this encounter followed by a group of corporate stiffs whom Clark wished Merry Christmas to and eventually told one to Kiss My Ass.
