 Originally Doris Singleton (qv) who played the recurring character  of Caroline (originally Lillian) Appleby on I Love Lucy (qv) was  supposed to costar on the series. Her character was supposed to be  Harrys 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 Lucys  family life with the kids than her job.
