A day at the spa is supposed to be relaxing, but not for one Chinese man that had a beauty treatment go horribly wrong. Metro UK explains in graphic detail how one excited eel ended up in Zhang Nan’s bladder after taking the scenic route through his urethra.

“I climbed into the bath and I could feel the eels nibbling my body. But then suddenly I felt a severe pain and realised a small eel had gone into the end of my penis,” the 56-year-old from Honghu, Hubei province said. “I tried to hold it and take it out, but the eel was too slippery to be held and it disappeared up my penis.”

The eel treatment is supposed to make a person look ten years younger by eating away at dead skin. In this case the eel probably took ten years off Zan’s life just from the pain and shock. We lost a couple years off the old ticker just reading this story.

So what happened to the overzealous little eel? He was found dead in Zan’s bladder after a three hour operation. See what happens when you try to get “a head.”
