Cinderfella

Keaton's new wife takes him home to her father and brothers, who all mistreat him terribly. His would be the lot of an overworked "Cinderfella" had the father not found the misappropriated letter, opened it, read of an inheritance, and assumed his son-in-law to be the beneficiary.

All my life I was an underdog who was now finally living out my Cinderfella story.

Of course I felt dreadful about using him, but still I somehow explained to Marty as we stood on the noisy sidewalk that I needed him to pose as my date for the night, and then like Cinderfella he would leave at midnight and go home like nothing had ever happened, although I suspected he had other plans.
