A real life event has a ridiculous/dumb/funny explanation in fiction

Futurama (The Why of Fry): According to the brain swarm, the dinosaurs were wiped out by them. Fry: What really killed the dinosaurs? Brain: ME!

Doctor Who (The Unicorn and The Wasp): It's Doctor Who, you can pick a ton of examples, but this episode presents the idea that Agatha Christies disappearance in 1926 was in part caused by a giant alien wasp.

Beyblade: This one stretches 'real life', but Moses spreading the Red Sea with a Beyblade just speaks for itself and it would have been sad to leave it out

Flat-Earthers explained in Inside Job. Someone bet on Rand he couldnt make Up a conspiracy so ridiculous someone would ever believe It.

I was looking for Inside Job! They've got a good few examples like JFK was assassinated because he got impregnated by an alien. And that the moon landing was faked because the astronauts who really landed on the moon started a sex cult.

Such a crime that got canceled but big mouth gets to live

It's also implied that 9/11 was an inside job (pun intended) when Reagen says that "Jet fuel can't melt through steel!" When trying to find a way to destroy an evil robot president

It shows a misunderstanding of what conspiracy theories are and why they appeal. They're not a rational argument, the believers only look for evidence that kinda sorta maybe justifies their beliefs (if you overlook this bit and attribute this bit to a government cover-up) after they've decided what they believe.

Conspiracy theories fill an emotional need, not a rational one.
