Hysteria 51 is your offbeat weekly podcast destination for all things weird and wonderful! We navigate the cosmic highways of UFOs, the alien-infested landscapes, and the enigmatic frontiers of the paranormal. With your hosts, Brent Hand and David Flora, alongside our cantankerous tin man, Conspiracy Bot (with a not-so-subtle desire to rule the world, doubling as our chief inquisitor into the unknown), we delve into unique mysteries, the inexplicable, and the downright unusual.
Each week, we explore a fresh topic, making one thing crystal clear... the truth is out there, but you won’t find it here.

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.
