On its official Twitter account, South Africa's Kruger National Park posted a photo of an elephant helping a lioness by carrying her cub in its trunk. The caption explained: "The elephant put its trunk down, the cub jumped up & the elephant carried the lion cub!!" The image quickly went viral, reaching over 20 million people, with many people (judging by their comments) appearing to believe that the image was real. Of course, it wasn't. In reality, lions and elephants are typically hostile to each other in the wild.
