A woman in China's Henan Province dropped her
$300 cellphone into a pit toilet (think: outhouse), and her husband was
nice enough to crawl into the pool of fecal matter to retrieve her
device. But, once he was in there, he was overwhelmed by the fumes
coming from excrement, and fainted.
While they were able to get everyone out in a matter of minutes, they had to wait over an hour for an ambulance to arrive, and the husband and his mother died.
(Note: with the amount of fecal matter in a large pit, methane gas can build up without proper ventilation, and can suffocate someone, as it did here.)
