I used to believe that when a man and woman slept in the same bed, that sperm would sneak out of the man's peen and creep across the bedsheets and into the woman's vagina, and that was how women got pregnant. I pictured the sperm to be about a half inch long with 4 little feet and really smirky looks on their faces.
