This was actually a real story, I am sure it was. I wonder if they did a DNA test.
I can remember a news story many years ago about a guy who had had a vasectomy and something like 7 years later his wife had a baby. They checked his sperm count and it hadn't spontaneously reversed (as they occasionally do). His wife's claim was that there must have been an old sperm lurking inside her, and when she fell down the stairs stairs one time she must have shaken it loose and it fertilised her. Her husband claimed to believe her.This was actually a real story, I am sure it was. I wonder if they did a DNA test.
