Friends don't let friends join cults.

In this one, Ian and Liv talk about a religious cult that began in the 1970s, "The Class," which barely survived for 20 years until the remaining 39 cult members, along with their leader, committed mass suicide in 1997. Eventually, this became cult became known as "Heaven's Gate," and has since become famous not only for their mass suicide, but the sheer absurdity of events that the cult leaders orchestrated during its span of two decades.

Spoiler Alert: The aliens don't arrive in Part 1.

Also, Liv gains self-confidence. Ian learns about the post office.

Just the tip.

In this one, Liv and Ian talk about a mudslide/landslide/avalanche that struck the town of Aberfan, Wales, in 1966. Among the victims were children in a school that was in the center of the mudslide's path.

Also, Ian discusses an alternate version of Shrek. Liv wants to go to Applebee's.

Y'all know the ocean is cold, right?

In this one, Ian and Liv talk about an oil rig that sank in the middle of the night during an intense storm. Rogue waves were involved. Did you know they're a real thing?

Also, Ian is delirious from working all day. Liv confirms that she only has one personality.

Part 2? It's time TWO sit down and listen.

In this one, Ian and Liv conclude their story on the Radium Girls in the second part of their first ever Two-Parter. What becomes of the Radium Girls? Does USRC get screwed in court? Was Marie Antoinette involved? Lots, yes, no.

Also, Liv is freaked out by the coyotes. Ian loves Erin Brockovich.

If it glows, it's probably dangerous.

In this one, Ian and Liv talk about the Radium Girls, five young women who filed a lawsuit against their employer for knowingly exposing them to a deadly radioactive chemical: Radium. And, as you can imagine, the corporate lawyers of the early 1900s would stop at nothing to prove their false innocence.

Also, Liv is ready for a suppository. Ian got a new keyboard.

Special Alert: Katie's back. In this one, Ian and Liv are joined once again by Katie to talk about a triple train wreck back in 2005 that resulted in 11 deaths. Fun fact: Costco employees are the best people to walk the face of the Earth.

Also, Katie argues about different types of trains. Liv learns about the original CSI show. Ian gets defensive over Thomas the Tank Engine.

Maritime safety is very important. In this one, Liv and Ian talk about two ships that crashed in 1917 in Halifax. If that wasn't bad enough, one ship was carrying a boat load (word play) of explosives, all which detonated simultaneously. Halifax was almost completely wiped off the map by the explosion, as well as the subsequent tsunami. To add insult to injury, there was a blizzard the following day in Halifax.

Also, Ian struggles to speak English. Liv is not an official Uber sponsor.

For the record, volcanos can kill you. In this one, Ian and Liv talk about the eruption of Mt. Pelee and the destruction of the nearby city, St. Pierre, on the island of Martinique in 1902. But the volcano isn't the only part of nature that claims the lives of civilians living near the volcano. Starving vipers, desperate for food and shelter, invade the city just before the eruption, adding more mayhem to the situation.

Also, Liv wants to touch lava with her bare hands. Ian does not.

How much dancing is too much? In this one, Ian and Liv are joined by friend and special guest host Ashley while they talk about one of strangest plagues in history: Dancing Plague. In 1518, hundreds of people in Strasbourg were compelled to dance, and couldn't stop no matter how hard they tried. And yes, people died from dancing. Probably from dancing the Jitterbug.

Also, Liv knows a lot of sayings. Ashley is reassimilated into society. Ian has never seen Footloose, staring Kevin Bacon.

Sometimes, "stop drop and roll" isn't enough in the event of a fire. In this one, Ian and Liv talk about a fire that broke out in a sweatshop in NYC more than 100 years ago. Pro tip: if you're looking to save a few bucks on the construction of a factory, the fire sprinkler system isn't the cut you should make. Don't learn that the hard way.

Also, Ian begins falling apart when he's tired. Liv has personal experience as a "town crier."
