Cheers, the tavern where everybody knows your name but not family-planning status. During the 1984-1985 season of the classic comedy, actresses Shelley Long and Rhea Perlman both became pregnant, but only Perlman's pregnancy was written into the script for her character, the wisecracking Carla Tortelli.
Long's pregnancy was purportedly hidden from the camera because her character Diane Chambers, fledgling waitress and self-proclaimed "student of life," was a single woman. For most of the season, Long was filmed behind the bar.
