Share, or your fingers will look like this

Oh, that is a pretty common photoshop. It's a plant that has pods that look like that. Usually they have seeds in them, but these don't.
This photoshop originated on 4chan's /b/ some 2 years ago, featuring a woman's breast with lots of these instead of nipples. And people were just as freaked out as you, until someone told them it was a photoshop.
Knees has also been photoshopped this way.
