There are simply far too many out of place artifacts in human history for us to do only one episode on the subject. This week we're back for part two of the strange and fascinating topic of things that seem as though they shouldn't be where - and when - they are.

Spencer dives into the Nazca Lines, and we discuss the massive crop-circle-style land carvings of 2,000 years ago, drawn into rock and illustrating monkeys, spiders, spider monkeys, monkey spiders, and maybe - just maybe, constellations.

Then, Ryan tells us about the Antikythera Mechanism - the oldest computer known to man, mapping stars in the sky to gears in a box on the ground. Found in a shipwreck in the early 1900's, the secrets of this artifact were only uncovered in the last 10 to 15 years.

Hot Topics: Barry Manilow the Alien, How to Get Abducted in 5 Features, Babies Digging Trenches, The Old Greek Dudes, and much more.
