This is exactly what happened to my cousin Sven back in St. Olaf. See the producers of I Know What You Did Last Summer were looking for a stunt double for Jennifer Love-Hewitt during the river boat scene. Well, unfortunately no woman in town had the upper body strength necessary to hold on to the fishing net recquired for the scene so they had to cast a man instead. Sven was able to impress the producers with his one man rendition of the King and I with his pet chicken and half-cousin, Bessie. The producers were in awe that he was able to insert the chicken dance into the play so perfectly. Well, when he did the scene a horrible accident from poorly wired pyrotechnics caused the prosthetic breasts Sven was wearing to permanently mold to his chest. After the movie was done filming he was able to get a job as St. Olaf's first human crash test dummy as his prosthetic breasts were able to absorb so much impact. Sven was never happier as it turned out he was really a woman trapped in a man's body with the love for dancing like a chicken
