(Upon learning that one man has nine girls)
Fred: Hey, you can always start a girl's softball team!
When this episode originally aired, Philip Morris had a special announcement regarding the birth of the Ricadro baby after the episode ended and before the credits rolled.
The movements of the scene where Ricky, Fred, and Ethel take Lucy to the hospital are carefully written out in the script. These actions were then rehearsed to make the scene as funny as possible.
The scene with Ricky singing in his voodoo costume is filmed the following week because there wasn't enough room on the soundstage for the hospital set and the Tropicana set.
The sex of the Ricardo baby was pre-determined to be a boy. Lucille Ball and Desi Arnaz thought that if they had a daughter on the show that it would confuse Lucie, their real life daughter, who would wonder why she wasn't on TV with her parents.
On January 19, 1953, Lucy Ricardo gave birth to Little Ricky on I Love Lucy and 92% of U.S. TV viewing audience were tuned in to watch. Lucille Ball gave birth to Desi Arnaz, Jr. that same morning. Newborn Desi Jr. was featured on the very 1st cover of "TV Guide". More people watched this episode than watched the ignauration of President Eisenhower the next day and the coronation of Queen Elizabeth.
As a side note, in a strange coincidence, on January 19, exactly 43 years later, Marlee Matlin gave birth to her daughter at the same time that the evening's episode of Picket Fences was being aired and her character on the show, Laurie Bey, was giving birth to a son.
Music performed on this episode included "Voodoo".
TV Guide and TV Land rank this episode #59 out the 100 memorable moments.
