After confusing a porcupine with an opossum, Antonio Rodrigues Mororó, 50, from Niterói, Rio de Janeiro, Brazil, was left with almost 400 porcupine quills stuck in his hand.
During a party at Mr Mororó's home, one of his son's said that his pregnant wife was afraid to enter the house because the animal was sitting on a wall by the entrance stairs.
So, in a bid to remove it, Mr Mororó slapped the animal, resulting in him receiving a handful of quills.
He was taken to the Emergency Unit of the local hospital and despite three shots of anaesthetic, the pain continued.
Following a tetnus jab and a course of antibiotics, Mr Mororó is recovering,
albeit with a hand full of holes.
Neighbours have reported that the porcupine is still living in the neighbourhood.
