Bananas, Crates, and Maybe-Monkey Debates: The De Loys' Ape Story | 463

Picture this:

You and 19 of your closest coworkers go into the jungle looking for oil. Three years later, only four of you come out. You’ve buried most of your friends, you almost died of disease, and somewhere along the way you shot what might be the first ever “American ape.”

Or...you shot a spider monkey, cut off its tail, and accidentally invented one of the dumbest racist “missing link” hoaxes in history.

Welcome to this week’s saga, the De Loys’ Ape, on Hysteria 51!
