A man in Brazil slapped an opossum this week. When Antonio Rodrigues Mororó was hosting a party at his house, he was informed an opossum was on his porch frightening a pregnant woman, so he decided to slap the animal away. The only problem? Well, other than why would you try and slap an opossum, is that the opossum he slapped wasn't an opossum at all. It was a porcupine.
