It's Christmastime, and Carly is depressed because all the kids are leaving to spend the holidays with their other parents. Jack just wants to get everyone ready and out of the apartment building. His reason: on his way in his car splattered their hapless neighbor Mr. Sandzimeier with water and caused him to fall down while carrying his groceries. Of course Jack can't escape a confrontation with him. Later, with the kids gone, Carly wants to do something meaningful for Christmas, like take Sandzimeier for a carriage ride. When they knock on his apartment door, though, they find that they've woken him up from a much-needed sleep now that he is getting ill from Jack's drenching. Carly and Jack return from their carriage ride to find a large puppy in the elevator. Carly insists they take it in for the night, against Jack's better judgment. They leave the dog in the living room for the night, where it proceeds to tear up the Christmas tree, decorations, presents and an odd pillow or two. W
