It has happened to babies, the narrator even said this is why drop gate cribs were banned
"Polly Wanna Crack Your Spine", has the parrot saying stuff like "You're dead", "Get your hands off me you dirty skank", and "Get on her and stay on her". She was just the housesitter, what goes on in that household?
The show took creative liberties to make a lot of its victims (aside from the ones that were just stupid) assholes so we wouldn't feel sad they died in horrible ways. This means a lot of the people who died in the real freak accidents these segments were based on probably weren't deserving of it, but normal Joes like you or I who just had bad luck.
"Drunk Die-er": The drunk driver who was still alive and had to not only watch his organs being harvested before they took out his heart, but feel every second of it. How do we know he's alive when there are no life signs actually? And how come highly trained doctors are so stupid to not notice he was alive either?
And if he died of it, how do we know he was still alive until they took his heart out?
There is a horror story similar to this, except mercifully the story ended just before they performed the actual autopsy and the guy just suffered a broken neck after falling off a tall building.
Easy solution: While the specific identity of someone who experienced this is unknown, it's common enough that it can be assumed to have happened at least once.
"Bushwhacked 3: Waxed Offed": The bitchy redhead at the Korean spa who died when doused with the water from the sprinkler system had a condition called aquagenic urticaria, which, in layman's terms, means "a deadly allergic reaction to water")... then how on Earth did this woman ever get properly clean?
People with this condition can only take 5 minute showers. The fire extinguisher was far more powerful than your average shower
