  Speaker 1: Welcome to Aaron Manke's Cabinet of Curiosities, a production of
• 0:07
  Speaker 1: iHeartRadio and Grimm and Mild.
• 0:12
  Speaker 2: Our world is full of the unexplainable, and if history
• 0:17
  Speaker 2: is an open book, all of these amazing tales are
• 0:20
  Speaker 2: right there on display, just waiting for us to explore.
• 0:25
  Speaker 2: Welcome to the Cabinet of Curiosities. There's nothing quite like
• 0:37
  Speaker 2: a desert island hypothetical. What movies would you take with
• 0:41
  Speaker 2: you to a desert island? Or albums, or in particular
• 0:45
  Speaker 2: who There are a million variations of the same question
• 0:48
  Speaker 2: that all boil down to one thing. What's important in
• 0:51
  Speaker 2: your life? What can't you live without? What these questions
• 0:55
  Speaker 2: don't really consider, though, is that desert islands aren't a
• 0:58
  Speaker 2: place that you bring your reality too. There are places
• 1:01
  Speaker 2: that create their own reality. Today, let's turn our focus
• 1:05
  Speaker 2: to Sable Island in the North Atlantic. If you're Canadian,
• 1:09
  Speaker 2: you might have heard of it, but for those who haven't,
• 1:11
  Speaker 2: it's a narrow stretch of island about ninety five nautical
• 1:14
  Speaker 2: miles southeast of Nova Scotia. From a satellite POV, it
• 1:18
  Speaker 2: kind of looks like a thin snake or a single eyelash.
• 1:22
  Speaker 2: The name comes from the French word for sand, and
• 1:24
  Speaker 2: it's easy to see why. The parts of the island
• 1:27
  Speaker 2: that aren't beach are covered in dry grass with no
• 1:30
  Speaker 2: native trees. Throughout the age of sail, shipwrecks on the
• 1:34
  Speaker 2: island were frequent, thanks to thick fogs and the island's
• 1:37
  Speaker 2: deceptive sandbars. It's estimated that up to three hundred and
• 1:40
  Speaker 2: fifty ships wrecked themselves on the island. The most recent
• 1:43
  Speaker 2: confirmed wreck was in nineteen forty one, although it's possible
• 1:47
  Speaker 2: some ships struck the island as recently as the nineteen nineties. Again,
• 1:52
  Speaker 2: looking at the shape of the island from above, it's
• 1:54
  Speaker 2: not hard to imagine it's like a tripwire designed to
• 1:57
  Speaker 2: catch unwary or unlucky vessel. But those shipwrecked sailors didn't
• 2:02
  Speaker 2: stay there. Those that survive often wind up getting taken
• 2:05
  Speaker 2: to the mainland of North America. The ones who did
• 2:08
  Speaker 2: stay behind there, Beside the gray seals that inhabit the beaches,
• 2:12
  Speaker 2: were around five hundred wild horses. Now we don't know
• 2:16
  Speaker 2: exactly where they came from, but most likely these horses
• 2:19
  Speaker 2: were introduced to the island in the mid seventeen hundreds
• 2:23
  Speaker 2: without any natural predators. They became the most influential population
• 2:27
  Speaker 2: on the island. For over two hundred and fifty years,
• 2:31
  Speaker 2: they've maintained a small but relatively stable population pun intended.
• 2:36
  Speaker 2: Other domestic animals.
• 2:37
  Speaker 1: Have also been brought to Sable Island, but none survived
• 2:41
  Speaker 1: quite like these horses. Survival for an animal on a
• 2:44
  Speaker 1: desert island is not easy. Water sources are sparse, and
• 2:48
  Speaker 1: the horses on the east side of the island have
• 2:50
  Speaker 1: to dig in the sand to create little wells for themselves.
• 2:54
  Speaker 1: You would never mistake a Sable Island horse for a
• 2:57
  Speaker 1: mainland horse. Their coats are thicker, shaggy aar and have long,
• 3:01
  Speaker 1: unkempt manes. Complete isolation from their more domesticated relatives has
• 3:05
  Speaker 1: made them a scientific marvel of sorts. They've experienced what's
• 3:09
  Speaker 1: known as a genetic drift away from the horses we
• 3:12
  Speaker 1: see in Europe and North America. Basically, they've almost become
• 3:16
  Speaker 1: a small subspecies of their own. And what's even more
• 3:19
  Speaker 1: fascinating is that these horses are more well adapted to
• 3:21
  Speaker 1: the environment than any plants that humans have attempted to
• 3:24
  Speaker 1: introduce there. At one point in the nineteen seventies, a
• 3:27
  Speaker 1: single Scots Pine was planted on the island by the
• 3:30
  Speaker 1: park rangers who maintain this station there. They decorated it
• 3:34
  Speaker 1: for Christmas, and it even survived for a number of
• 3:36
  Speaker 1: years before finally dying and returning the island to its
• 3:40
  Speaker 1: original treeless state. The horses themselves pose an interesting question
• 3:44
  Speaker 1: for conservationists. They're clearly an invasive species, but they are
• 3:48
  Speaker 1: incredibly valuable to understanding how species adapt to hostile environments
• 3:53
  Speaker 1: and how a single population of animals can gradually reshape
• 3:57
  Speaker 1: the same environment. Removing them would perhaps be good for
• 4:00
  Speaker 1: the biodiversity of the island itself, But since the horses
• 4:04
  Speaker 1: have been on the island for so long that ship,
• 4:07
  Speaker 1: so to speak, has sailed. There's no buried treasure to
• 4:10
  Speaker 1: be found on Sable Island in spite of the prodigious
• 4:13
  Speaker 1: number of shipwrecks. But in a way, the march of
• 4:16
  Speaker 1: history has left its own strange fingerprint all the same.
• 4:20
  Speaker 1: Who would have thought that feral horses could thrive on
• 4:22
  Speaker 1: a thin sandbar thirteen square miles in area. But that's
• 4:26
  Speaker 1: the thing about desert islands. They always bring out the
• 4:29
  Speaker 1: unexpected in all of us. When there's nothing but you,
• 4:33
  Speaker 1: the sand and the ocean. You either need to escape
• 4:37
  Speaker 1: or adapt. You've probably heard people say that laughter is contagious,
• 4:54
  Speaker 1: but that isn't always just a turn of phrase. On
• 4:57
  Speaker 1: a January morning in nineteen sixty to a teacher was
• 5:01
  Speaker 1: writing on the chalkboard at a girl's boarding school in
• 5:04
  Speaker 1: the African republic of Tanganika. She heard laughter behind her
• 5:08
  Speaker 1: and turned around to see three of her students giggling uncontrollably.
• 5:12
  Speaker 1: This wasn't unusual for a classroom full of teenage girls,
• 5:16
  Speaker 1: but when the teacher asked them to stop, they didn't. No,
• 5:20
  Speaker 1: they couldn't. Beneath their smiles, there was a spark of
• 5:24
  Speaker 1: fear in their eyes, as if their laughter truly was uncontrollable.
• 5:29
  Speaker 1: The teacher sent the girls to the principal's office and
• 5:31
  Speaker 1: got on with the lesson. But at the end of
• 5:33
  Speaker 1: the school day, when she passed by the nurse's office,
• 5:36
  Speaker 1: she saw those three students and two more girls, all
• 5:39
  Speaker 1: doubled over in their chairs, all still laughing, with tears
• 5:43
  Speaker 1: streaming down their faces. It was hard to tell whether
• 5:46
  Speaker 1: they were amused or agonized. Their laughter hadn't stopped the
• 5:50
  Speaker 1: following morning, In fact, it was spreading several more girls
• 5:54
  Speaker 1: in the same dormitory had to skip class that morning
• 5:57
  Speaker 1: because their laughter was so intense that they could barely
• 6:00
  Speaker 1: sit still. Each girl's laughing fit could last for anywhere
• 6:03
  Speaker 1: from a few hours to multiple days, and after they
• 6:06
  Speaker 1: had finally stopped giggling, some of them would start up
• 6:09
  Speaker 1: again just a few minutes later. Within a week, almost
• 6:13
  Speaker 1: one hundred students at the school were afflicted. There was
• 6:15
  Speaker 1: no end in sight, and the staff had no idea
• 6:18
  Speaker 1: what to do. The students had been examined by doctors
• 6:21
  Speaker 1: and nothing appeared to be physically wrong with them. It
• 6:24
  Speaker 1: had to be psychological, perhaps induced by stress. If this
• 6:28
  Speaker 1: was a subconscious ploy to get out of doing homework,
• 6:31
  Speaker 1: it was working. With more than half of the school's
• 6:34
  Speaker 1: students doubled over in laughter at any given moment, it
• 6:37
  Speaker 1: was impossible to conduct class, and when the madness still
• 6:40
  Speaker 1: hadn't died down by March, almost three months after it began,
• 6:44
  Speaker 1: the administration was left with only one option. They decided
• 6:47
  Speaker 1: to close the school and send everyone home until they
• 6:51
  Speaker 1: got their giggles under control, and that was a mistake.
• 6:55
  Speaker 1: The students went back to their home villages and they
• 6:58
  Speaker 1: spread the laughter up add throughout the entire region. Over
• 7:02
  Speaker 1: the next two months, around one thousand young people over
• 7:05
  Speaker 1: one hundred mile radius were afflicted by laughter. Fourteen schools
• 7:10
  Speaker 1: had to be shut down, and the school where it
• 7:12
  Speaker 1: all started was slapped with a lawsuit for sending everyone
• 7:15
  Speaker 1: home to transmit the contagion. The laughter came and went
• 7:19
  Speaker 1: in waves for the next year and a half until
• 7:21
  Speaker 1: it gradually died out in the summer of nineteen sixty three.
• 7:25
  Speaker 1: Order was restored and schools were reopened, but experts were
• 7:29
  Speaker 1: never able to explain exactly why this outburst happened. Some
• 7:33
  Speaker 1: researchers speculate that it was a case of mass hysteria.
• 7:37
  Speaker 1: Just a month before the laughter started, Tanganika had gained
• 7:40
  Speaker 1: independence from Britain, which began a period of massive social upheaval.
• 7:45
  Speaker 1: On a subconscious level, maybe the girl's laughter could have
• 7:48
  Speaker 1: been a way of releasing stress and coping with the
• 7:51
  Speaker 1: chaos and confusion. But at the end of the day
• 7:54
  Speaker 1: it backfired. After eighteen months of NonStop chuckling, everyone could
• 7:59
  Speaker 1: agree the joke just wasn't funny anymore. I hope you
