The actress, 41 at the time, had scheduled a C-section to coincide with the episode—an idea the CBS network and one of the show’s advertising sponsors opposed at first. Sure enough, when the episode was airing and the fictional Lucy was giving birth to Little Ricky, the real-life Desi Arnaz Jr.—son of Ball and husband Desi Arnaz—entered the world at 8 pounds and 1 ounce. On the show, TV husband Ricky Ricardo wreaked comic havoc in the waiting room by putting on his freaky costume for a band performance that evening.
Incredibly, the birth episode garnered more media attention than really big news the next day: the inauguration of President Dwight D. Eisenhower on January 20, 1953. Ball recalled: “Sixteen years later, President Eisenhower was standing with us outside the El Dorado Country Club and he pointed to my son and said, ‘Is that the young man who knocked me off the front pages?’”
It was lucky that “Lucy” writers wrote a baby boy into the script, show editor Dann Cahn said in an interview with the Television Academy: “The child being a boy [in the show] had been decided weeks earlier. Remember, there was no ultrasound testing—they didn’t know if it was twins, whether it’s a boy or a girl, or two boys or whatever. They didn’t have that in the ’50s.”
Ball died at age 77 on April 26, 1989, in Los Angeles. The famous-upon-birth Arnaz Jr. grew up to become an actor and musician.
