Originally Doris Singleton who played the recurring character of Caroline (originally Lillian) Appleby on I Love Lucy was supposed to costar on the series. Her character was supposed to be Harry's efficient morning secretary, opposed to Lucy, his scatterbrained afternoon secretary. Her character was dropped after the first episode, because it was decided to show more of Lucy's family life with the kids than her job.
The series dropped out of the top 10 Nielsen ratings in its fifth season. This was the first time that a series starring Lucille Ball was not in the top 10. Because of this, Ball wanted to end the series and a final episode was filmed. But CBS convinced Ball to return for one more season.
