The "no shooter" theory is pretty far out there.

Microsoft, the state of South Dakota, and the Freemasons have been infiltrated by the Unified Buttjones Imperial Court (UBIC), formed in 1834 by the merger of the Imperial Buttjones Society and the All-Ireland Industrial Arsing Federation. UBIC agents camouflage themselves as janitors, assistant product managers, or beagles, and spread an invisible green slime over toilet seats to infect the minds of their targets. Through this mental infiltration, they obtain control over the vazween or pony-flavored sector of the human soul, creating Inter-Vazween Buttjones Networks (IVBN) through repeated application of the Greater Invoking Pentacle of Pony Erotic Revelation (GIPPER). Using an apparatus constructed from illegal immigrants, UBIC uses the IVBN and GIPPER to insert bugs into Windows, Masonic initiations, and the Lewis & Clark State Recreation Area. Anyone who denies this obvious truth is a buttjones.

Kangaroos don't exist

My pet conspiracy theory that California does not exist. It was invented by democrats to pad their electoral votes. Any one who has traveled there actually went to a staged area in Oregon. Anyone who claims to live there is either brainwashed or in on it. Maps, globes, etc. have all been altered. Satellites have special software that adds California to its images. Spacecraft windows are actually screens that digitally alter earth to add California.

Once you consider that California is allegedly the location of Hollywood and movies often create convincing, fake worlds, it makes sense. Hollywood was created to take advantage of the tech developed to fake California and continue funding the conspiracy...

The one where the Nazis found an Antarctic hole into a hollow earth world with aliens/lizards inside it... And that's where they were getting their tech.

That Stalin was the "good guy".

I make a YT channel about bizarre conspiracy theories. I keep coming back to the people who make videos claiming that 5G is actually a deadly weapon on their 5G Iphone 16. Nobody has more cognitive dissonance than these guys.

Lizard people wins the price, hands down.

I haven't been able to find this theory again because searching for it brings up the moon landing conspiracy, but some people think that there's a second, fake moon which is why the moon rises and sets twice a day.

Donald Trump is really Andy Kaufman method acting.

"Michelle Obama is a man"

Qantas used to have a 'u' in it, but they changed their name so now you don't even know!

That's like asking who the craziest person is. Like, there's so many to choose from, and they get less and less well known as you go nuttier and nuttier.

The Mandela Effect is pretty wild, but it’s also the most explicitly mental-health issue adjacent of an already “are you sure you’re ok?” field.
