The episode opens with a tongue-in-cheek 'true crime podcast' parody involving stolen Reese's candy, a winking nod to the Morbid audience before the proper content begins. State Farm's Personal Price Plan and Thumbtack's home-pro app each get brief sponsor reads, rounding out the cold open before the hosts take over.
Ash opens by announcing Amusement Park Disasters Part 2 before the two hosts fall into a genuinely illuminating conversation about risk. Ash explains she has zero interest in any form of thrill-seeking and traces that back to her Capricorn Sun, Virgo Rising, Cancer Moon chart — a personality perfectly designed to stay alive. Alaina, by contrast, sees risk as background noise and suspects her own calculus will shift once she has children. They land on a distinction that matters: Ash doesn't avoid thrills entirely — she loves haunted houses and horror films — but she refuses any thrill that carries genuine bodily risk. The hosts also announce their Radio City Music Hall show with special guest Jonathan Van Ness and tease the upcoming Butcher Legacy Tour before segueing into the main content.
Ash sets the scene with Disneyland's July 1955 opening, when early rides like the Railroad and Astro Jets were a far cry from today's hyper-modern attractions. The Matterhorn's origin story is perhaps the episode's first surprise: engineers repurposed the massive pile of excavation debris from Sleeping Beauty's Castle rather than hauling it away, eventually shaping it into the iconic 'mountain.' Named Holiday Hill, then Lookout Mountain, it became the Matterhorn in 1956. Walt Disney then conceived a toboggan-style ride through the structure, which opened in 1959 as the world's first tubular roller coaster — allowing the sled to pass through tunnels and holes in the mountain's walls.
The episode's first genuine horror arrives with the story of Mark Maples, 15, who boarded the Matterhorn with friends Doug Gibbs and Gary Payne on a May evening in 1964. At the steepest descent, Mark was thrown violently from the sled headfirst. Initially, park attendants refused to believe the boys' account and had to be corroborated by girls in the car behind before they searched the tunnel and called paramedics. Mark was found unconscious and bleeding; he never regained consciousness and died four days later. The coroner ultimately concluded the death was purely accidental and that Mark had unbuckled his own seatbelt 'for no explainable reason,' though hints of a hazing by a social club called Phidias were investigated and dismissed. Disneyland's official position — that Mark stood up and fell out — was backed by a test in which no one of Mark's size could free themselves while buckled.
Two years after Mark Maples's death, another young man paid with his life for trying to circumvent Disneyland's security. On June 18, 1966, Thomas Cleveland, 19, learned the park would host an exclusive all-night graduation party and hatched a plan: scale the 16-foot perimeter fence, climb a monorail pylon, and walk the track until he reached his friends. Security guards spotted him and shouted warnings, but rather than jump down, Thomas tried to hide on the fiberglass canopy between the rails. He apparently hadn't considered that the monorail would still be running while the park was occupied. As the train rounded a corner at 25 miles per hour, it struck Thomas. Monorail driver Dallas Baker never saw him — he only knew something had happened because he felt a bump. Thomas was killed instantly, and the coroner ruled his death purely accidental with no liability for Disneyland.
Seven years after Thomas Cleveland's death, two brothers found a different way to try to get free entertainment at Disneyland. Bogdan Dellerot, 18, and his 10-year-old brother Dorian took the ferry to Tom Sawyer's Island in June 1973 and hid from security until after the park closed. Then they entered the water to swim back to shore. Dorian quickly exhausted himself, and Bogdan tried to carry him by having Dorian wrap his arms around his neck — a decision that proved fatal. Both became too tired to continue. Park security heard Dorian's cries and rescued him by boat, but Bogdan had already slipped beneath the surface. His body was found the following morning, lodged in the rapid section of the river. A decade later in 1984, a similar tragedy would strike the same waterway when two drunk visitors stole a maintenance boat, hit a rock, and one drowned.
The Columbia disaster is arguably Disneyland's most egregious case of operational negligence. Park employee Christine Carpenter threw a mooring line around the Columbia's iron cleat while the tall ship was still moving, putting catastrophic tension on the hardware. The cleat's bolts sheared and the 8-pound, 12-inch iron fitting launched into the crowd at tremendous force — striking Carpenter in the foot first, then hitting Liu Tui Vuong in the face and her husband Luan Phi Dawson in the head. Luan was declared brain dead by the time he reached UC Irvine Medical Center and died that same evening, on Christmas Day. Liu underwent extensive surgery that left permanent nerve damage and paralysis on the right side of her face. A deputy coroner determined the accident was caused by Disney's failure to follow docking procedure. More troubling still: when a detective arrived, he was kept waiting in a conference room and found the accident scene had been entirely cleaned up, with the broken cleat and two teeth located later in a dumpster.
California's Great America, developed by Marriott and opened in 1976, was a smaller-scale competitor to Disneyland. Its flagship ride, Willard's Whizzer, was also its most dangerous: the braking system repeatedly failed to engage, and trains sometimes bumped each other at the terminal. Eleven injury incidents were documented before a 1979 evaluation. The fatal accident came on March 29, 1980, when 13-year-old Kyle Foss was climbing aboard the last car in a Whizzer train as a second train rolled in. A 'false electrical signal' had tricked the braking system into thinking it was holding a phantom train; when the system corrected itself and released the brakes, the real train was already pulling in, and it struck the car where Kyle was standing. He was crushed to death. Three other passengers were ejected from the ride and landed in a pond. Despite park officials initially claiming nothing was wrong, Vice President J. Robert Schultz's own technical explanation made clear the ride's electronics had misfired fatally.
The Great America Top Gun incident of September 7, 1998 begins as a cautionary tale about restricted zones but pivots into something far stranger. Newlywed Hector Mendoza and his brother-in-law re-entered the secured perimeter of the inverted roller coaster to retrieve a blown-off baseball cap. Just as he picked it up, the coaster rounded the corner and a dangling passenger foot struck him in the head at full speed, killing him instantly and breaking the passenger's leg. Great America and the victim's family disputed whether the gate was locked, but police backed the park's account. Then, a week after the accident, fingerprint analysis revealed the dead man's documents were fraudulent: the real Hector Mendoza was alive in Mexico. The victim was eventually identified as Suárez Robles, adding a layer of identity-crime mystery to an already tragic story.
Less than a year after the Top Gun tragedy, Great America faced another fatality, this time with no reckless behavior on the victim's part. Joshua Smurfett, 12, rode the Drop Zone free-fall tower with his family in August 1999. An attendant checked and confirmed every harness before the car ascended. At the 207-foot mark, Joshua slipped out and fell 20 stories while his family watched helplessly from below. Investigators could not determine how he escaped a properly functioning harness, but the 900-page incident report exposed deep systemic problems: the ride attendant that day was 14 years old and the one who had checked the harnesses was 16. Joshua's mother Tammy chose not to sue, asking only that parents treasure every moment with their children. His father hired a lawyer but ultimately the family did not pursue civil action, leaving the exact cause of the harness failure unresolved.
The episode pauses for a cluster of sponsored reads. Füm markets itself as a nicotine-free oral-fixation substitute that has helped over 700,000 people break habits. Quince promotes its European linen summer clothing line with a personal endorsement from Alaina, who describes styling linen pants for both casual and dressed-up occasions. BetterHelp, the world's largest online therapy platform, is pitched by Alaina in a personal segment about people-pleasing and stigma around mental health. All three sponsors offer exclusive listener discounts.
Eugene Mulvihill was a ski resort owner looking for off-season income when he conceived Action Park in 1978 — and his son Andy's memoir makes clear he had no idea what he was doing. Rather than engineering safety into rides, Mulvihill embraced risk as a brand identity, convinced Americans were tired of being 'coddled.' Wave pools were designed to simulate mini-shipwrecks; slides had no speed controls. The park grew from hundreds of visitors in its first season to millions within two years, even as visitors emerged bleeding, stinking of diesel fuel, and clutching Band-Aids. The first death came in July 1980 when 19-year-old George Larson was ejected from the Alpine Sled, rolled down an embankment, and struck his head on a rock 25 feet from the ride. The park's spokesperson argued it was the rock's fault, not the ride's. An investigation by the state Department of Labor found seven safety violations, including no emergency access road, but ruled the death accidental.
Action Park's wave pool was marketed as thrilling entertainment but functioned as a recurring death trap. In 1982 alone, 15-year-old George Lopez drowned in the wave pool and 27-year-old Nathan Langenthal was electrocuted in the whitewater kayak ride — the New Jersey coroner officially ruling heart failure by electrocution. State investigators later found a short circuit in one of the wave-producing fans, yet Action Park's owner Eugene Mulvihill told reporters Langenthal had 'probably had some kind of stroke.' In 1984, 20-year-old Donald DePass drowned after rocketing off a 10-foot slide into the pool. In 1987, 18-year-old Greg Grandchamps drowned in the wave pool; the prosecutor's investigation found lifeguards had not attempted CPR after pulling him out. Marketing director Vernon Merritt's response — 'we're not quite sure he was not resuscitated' — became one of the episode's darkest moments of corporate deflection.
The end of Action Park came not from a single tragedy but from financial exposure. When creditors discovered the park carried zero liability insurance, they forced Eugene Mulvihill into bankruptcy and the park shuttered in 1996. In the years after closure, more damning details emerged: rides were routinely designed by non-experts on shoestring budgets, employees were mostly undertrained local teenagers, and the park's 'enter at your own risk' ideology actively encouraged reckless behavior. Ash reads Andy Mulvihill's own summary — that Action Park admitted misfits and clergymen alike, gave them total freedom, and sometimes paid for that freedom with visitors' lives — before Alaina draws the episode's sharpest observation: America right now feels a lot like Action Park.
After the weight of Action Park's legacy, the hosts decompress with their signature warmth. Alaina drops the episode's fun fact — cows have regional accents and become depressed when separated from close friends — which circles back to Alaina's dream of petting a Highland cow in Scotland. The closing sign-off is followed by a post-roll block featuring Morgan Morgan injury law firm and a Chumba Casino promotion tied to WWE SummerSlam. The episode ends on the hosts' characteristic note: keep it weird, but not so weird that you open an amusement park without safety protocols.
tubular roller coaster
A roller coaster that runs on two parallel hollow steel tubes rather than a wooden or single-rail track, allowing tighter turns and more complex paths including tunnels — the Matterhorn Bobsleds was the world's first, opening in 1959.
cleat
A T- or horn-shaped metal fitting bolted to a ship or dock, used to secure mooring lines; the 8-pound iron cleat that killed Luan Phi Dawson at Disneyland sheared off when excessive tension caused its bolts to fail.
mooring line
A rope or cable used to tie a vessel to a dock or fixed point; securing it before the ship has stopped creates dangerous tension that can cause hardware like cleats to shear off at high velocity.
inverted roller coaster
A roller coaster design where seats hang below the rail rather than sitting on top of it, leaving passengers' feet dangling — the configuration that made it possible for a dangling foot to strike someone standing under the track at Great America.
shoestring budget
Extremely limited financial resources; used here to describe the minimal capital Action Park devoted to ride construction, contributing to unsafe designs.
libertine
Free from conventional moral or legal restraints; used to describe Action Park's operating philosophy of encouraging visitors to disregard safety rules and behave recklessly.
coroner's inquest
A formal legal inquiry conducted by a coroner to determine the cause of death, sometimes with a jury; in Mark Maples's case, an inquest was ruled out after the coroner concluded his death was accidental.
CPR
Cardiopulmonary resuscitation — an emergency procedure combining chest compressions and rescue breathing used to sustain circulation in a person who has stopped breathing; Action Park lifeguards failed to perform it on a drowning victim in 1987.
short circuit
An unintended electrical connection that causes current to flow along an unplanned path, potentially generating heat, sparks, or electric shock; investigators found one in an Action Park wave-pool fan after a visitor was electrocuted.
allure
Powerful attraction or fascination; used here to describe how the notoriety and danger of Action Park paradoxically increased its appeal to visitors rather than deterring them.
pragmatic
Dealing with things sensibly and practically rather than theoretically; Alaina uses it to describe Ash's analytical approach to risk assessment.
sheared off
Broke away suddenly under lateral or tension force, as when the bolts holding the Disneyland Columbia's iron cleat were overcome by the strain of the moving ship.
pylon
A large vertical structural support, such as the concrete columns that held up the Disneyland Skyway; the Matterhorn was built partly to conceal one of these.
hazing
Rituals of initiation imposed on new members of a group, often involving humiliation or physical risk; speculated as a possible cause of Mark Maples unbuckling on the Matterhorn, though never proven.

Action Park grew from a few hundred visitors in its first season to millions of visitors within a year or two of opening.
Action Park's founder Eugene Mulvihill had zero amusement park experience when he opened the park in 1978, but he intentionally built risk into the brand. Visitors could control their own speed on slides with no track, cling to rafts in wave pools designed to simulate shipwrecks, and were quietly encouraged to behave recklessly.
In 1980, 19-year-old George Larson was thrown from an Alpine Sled at Action Park and smashed his head on a rock 25 feet away. Action Park's spokesperson told reporters it wasn't the ride's fault — it was the rock. An investigation found no emergency vehicle access road existed at the park.

Action Park lifeguards failed to attempt CPR on 18-year-old Greg Grandchamps after pulling him from the wave pool where he drowned in 1987.
Ash KelleyProsecutor's office investigation into Greg Grandchamps's death
Action Park's wave pool killed at least three visitors — 15-year-old George Lopez in 1982, 20-year-old Donald DePass in 1984, and 18-year-old Greg Grandchamps in 1987. After Grandchamps drowned, investigators found lifeguards hadn't attempted CPR. The park's response: 'We're not quite sure he was not resuscitated.'
In 1982, 27-year-old Nathan Langenthal died in Action Park's whitewater kayak experience. The coroner ruled heart failure by electrocution; investigators later found a short circuit in a wave fan. Eugene Mulvihill's response: 'He probably had some kind of stroke or something.'
Action Park denied electrocution killed Nathan Langenthal in 1982 even after the coroner ruled heart failure by electrocution and investigators found a short circuit in a wave-pool fan.
Action Park operated for 20 years with near-hourly injuries and no liability insurance, finally closing in 1996 only when creditors forced bankruptcy proceedings.

Action Park Closes — And the Verdict on 20 Years of Chaos
The end of Action Park came not from a single tragedy but from financial exposure. When creditors discovered the park carried zero liability insurance, they forced Eugene Mulvihill into bankruptcy and the park shuttered in 1996. In the years after closure, more damning details emerged: rides were routinely designed by non-experts on shoestring budgets, employees were mostly undertrained local teenagers, and the park's 'enter at your own risk' ideology actively encouraged reckless behavior. Ash reads Andy Mulvihill's own summary — that Action Park admitted misfits and clergymen alike, gave them total freedom, and sometimes paid for that freedom with visitors' lives — before Alaina draws the episode's sharpest observation: America right now feels a lot like Action Park.
