Yes, you read that right. Zhang Nan, a 56-year-old Chinese man, was bathing with live eels, in the hopes that the tiny, serpentine critters would nibble away layers of dead skin, revealing more youthful-looking skin below.

At one point, Nan felt a sharp pain and realized a 6-inch eel had entered his penis and was wriggling up through his urethra. He tried to pull it out, but its tiny body was too slippery to hold, and it disappeared up his penis and into his bladder.

Although strange, this is not the first time such an incident has been described: A teenage boy had to undergo emergency surgery to remove a 0.79-inch fish that climbed into his urethra while he was holding it and urinating.
