:Checks calendar to make sure its not April fool's day again...:

Are you talking "real life" Orcs?

The closest thing to a real life Orc is some of the early ancestors of the Human species, called "hominids" (spelling?). We have found Dinosaurs and other early life forms going back millions of years but no Orcs yet. I think some evidence would have come up by now.
Let me check the calendar again, I apologize if your post was serious, but man...
