Someone snapped a photo of a father and his son wading in the ocean, but when they looked at the picture, it was pretty disturbing.
Because of an optical illusion, the photograph showed some kind of Benjamin Button old-boy.
The pair's heads are positioned in just the right way so it looks like the boy has a man's face. Even if you stare at the pic, it's still hard to tell what exactly is going on.
To help you out, we outlined where the child's face ends, but even with the help, it's impossible to unsee the manboy.
