Mall Santa: We're doing this for the kids.
Howard: For the kids?
Mall Santa: For every kid who ever sat down on Santa's lap, for every little girl who left cookies and milk for Santa on Christmas night, for every little boy who opens a present Christmas morning and finds clothes instead of toys. Aw. It breaks my heart.
The Mall Santa to Howard explains that they do this for the kids and expounds on all the kids who do not get what they want for Christmas. He gets all emotional and tells Howard that it breaks his heart.
