Feeling a little eel?
The un-named patient rushed to A&E in Auckland last week with the embarrassing problem.
Medics x-rayed the man and discovered the fishy visitor wedged inside him.
It's unclear how the eel ended up inside the man - but staff at the hospital insist it's the weirdest medical emergency they've ever encountered.
A hospital source told the New Zealand Herald: "The eel was about the size of a decent sprig of asparagus and the incident is the talk of the place.
"Doctors and nurses have come across people with strange objects that have got stuck where they shouldn't be before, but an eel has to be a first."
After a painful procedure, doctors removed the slippery intruder and the red-faced man was sent home.
"No further comment will be made out of respect for the patient's right to privacy."
