A Croatian woman was left with a severely burned anus after a lightning strike which entered through her mouth left her body through her bottom. The lightning reportedly struck Natasha Timarovic's building as she was cleaning her teeth – with her mouth to the tap, sending the current through her body. And as she was wearing rubber-soled shoes, the lightning bolt was unable to earth through her feet – so it took the next easiest route, and came out of her rectum. http://www.metro.co.uk/weird/article.html?in_article_id=20883 Now there's an experiment I bet Ben Franklin Never Tried!
I can't even imagine how much that would hurt, with lightning going through your entire body and that leaving at a place like that.
