Never let it be said that the human species isn't diverse, particularly when it comes to intelligence. From the Huff Post:
A man in China's southeastern Guangdong province admitted himself to a local hospital after he reportedly got a live eel stuck inside him. According to British tabloid The Sun, the man inserted the 20-inch-long Asian swamp eel into his anus after seeing it done in a porn movie, and he had to endure all-night surgery to have it extracted.
According to a HuffPost translation of Chinese news aggregation website Mop.com, the eel reportedly chewed through the man's colon, perforating his large intestine, and became stuck in his body cavity.
Incredibly, the eel was still alive when they pulled it out, but died shortly afterwards. The man lived to tell the tale (although it's hard to imagine he'd actually confess to his little 'experiment'), but may be facing charges of animal cruelty.
Sadly in China, they don't prosecute immense stupidity.
