A page of the script for the famous episode titled “Lucy is Enceinte,” in which Lucy tells Ricky that she's pregnant. Months before Lucy Ricardo was with (scripted) child, Ball found out she was pregnant in real life. Ball and Arnaz assumed that the pregnancy would mean an end to I Love Lucy because pregnant women were verboten on television. But Jess Oppenheimer, the show's creator, decided to write the pregnancy into the Lucy scripts. He soothed the nerves of the network by having a priest, a rabbi, and a minister vet every pregnancy-related script to make sure it wasn't in any way offensive. And, famously, the word pregnant was never said on the I Love Lucy show.
