Big Bill catches a cold and has to stay home from work. Little Bill volunteers to take care of him, but Bill and Brenda insist he go to school so he doesn't get sick, too. At school, Little Bill can't concentrate because he's worried about Big Bill; Fuschia, Andrew and Kiku suggest they make a Get Well card for Mr. Bill, like they did when Little Bill had Chicken Pox, to cheer him up. During music time, the children make up a Get Well Song that Miss Murray records so Little Bill will have a copy to bring home. When Little Bill comes home from school and gives Big Bill the card and the tape, his father says the thing that made him feel better was having Little Bill do all these nice things for him.
