A little advice: If you drop your phone in the toilet, think twice before going after it. Otherwise you could end up like this man in China who did that and had to be rescued by firemen. On television.
The man in this video lives in China's Jiangsu province. He dropped his phone and it disappeared down the little hole, so he went shoulder-deep trying to get it back. 10 minutes and a few crowbars later he was freed. And now he's all over Chinese television. Poor guy.
