Pierced!

(January 2008, Pennsylvania) A 23-year-old man with various body piercings wondered what it would feel like to connect his workplace test equipment to his chest piercings. Several co-workers tried to convince him that it was a bad idea to wire himself up to the electronic control tester, but he ignored their pleas.

He proceeded to connect two alligator clips to his piercings and hit the test button...

When the police and rescue personnel arrived, his co-workers were stiill trying to revive him with CPR and rescue breathing. They were not successful.
