This year, Santa and Mrs. Claus are having their entire family over for Christmas dinner. There’s Uncle Alfred the inventor from Bermuda; Sister Olga the opera singer; eight young children, including Baby Wllie; even a polar bear named Oscar. With a family like this, mayhem is bound to follow, and from a snowball fight to the Christmas pageant, it’s a wild affair. But in the spirit of the season, everyone has a wonderful time—even the frazzled hosts!
