Джек и Сара

Jack always lands on his feet. He lands on his feet when he marries the beautiful Sarah. He lands on his feet when he buys a luxurious new home. However, when Sarah goes into labour, 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 1.

She's not proper, she's not fitting, she's not British, but to Jack she's a breath of fresh air.
