Jack & Sarah (1995)

Jack (Richard E. Grant) always lands on his feet. He lands on his feet when he marries the beautiful Sarah (Imogen Stubbs). He lands on his feet when he buys a luxurious new house. However, when Sarah goes into labor, he takes a tumble down the stairs and lands on his head. When he comes around, he discovers he is the proud father of a baby girl, but deficient in the spouse department to the tune of one. He hires the help of a novice nanny, but at the end of the day, it's Jack who's left holding the baby.
