The sixth season of Married... with Children (1991–1992) is defined by one of the most infamous storylines in sitcom history: . The Main Storyline: The Pregnancy Arc
The season opens with a two-part premiere, "She's Having My Baby," where Peggy reveals she is pregnant, followed immediately by Marcy. This sets up a season-long arc featuring Al’s increasing misery and Marcy’s hormonal shifts.
In reality, actress Katey Sagal was pregnant, but she tragically lost the baby six weeks before her due date. To spare her the pain of working with a baby on set, the writers turned the entire pregnancy storyline into an imaginary nightmare Al had while he was on a "trip around the world" in his mind.
