I hear Lucille Ball insisted on sharing the same bed with her real husband of that time; Ricky Ricardo. Nobody’s feet were on the floor.
When she became pregnant with little Lucy, Lucille again insisted on appearing in front of the cameras as obviously with child. It was time for the TV world and it’s public to grow up a little bit.
The Lucy show when she was pregnant and went into labor was hilarious.
The Hays code was in effect until 1965.
The Hays Code even extended to animated cartoon movies to such an extent that the ‘career’ of the famous cartoon character Betty Boop was ruined.
The Hays Code required that women, in love scenes, at all times have “at least one foot on the floor” (in other words, no love scenes in bed).
People could not be in a horizontal position if they were kissing.
