Technically speaking, I am pretty sure he can still have sex. It just won't be with a woman, and he won't be on top.

As for people dying, I did see a reference to an 18-year-old freshman at Tiffin College (in Seneca County, Ohio), who was trying to imitate a Jackass stunt and rode in the back of a pick-up truck, set a chair on fire, threw it onto the roadway. He then either fell or jumped while being videotaped by his friends. County officials said the youth died from massive head injuries.

And remember when the movie "The Program" came out (1993)? There was a scene where the kids were laying in the middle of a country road at night, to see how close the cars would come to them or something. This scene was copy-catted by real-life teens, and three were killed (plus two critically injured) in Pennsylvania, Texas, New Jersey, and New York. Touchstone Films responded by deleting the scene from all prints.
