1. Australia doesn’t exist

That Australia doesn’t exist. It is a massive cover-up for Britain killing hundreds of thousands of prisoners at sea and just saying they sent them to Australia.

It gets even more ridiculous in the continuation of the cover-up. Apparently all airplane pilots and boat captains are in on it and whenever anyone “visits” Australia it is actually a cleared out section of land in South America that has thousands of actors paid to be “Australian”.

8. The Vincent Van Gogh was Jack the Ripper

I will always find the theory that Vincent Van Gogh was Jack the Ripper quite funny. Just… the sheer amount of work and thought the guy has put into this.

9. Eric Clapton was a serial killer

My favorite isn’t widely known, I’m pretty sure just this one crazy homeless dude in my city believes this but here it goes. Eric Clapton is mediocre at best and we all know about him pushing that kid out of the window so he could write a number one hit but this theory digs deeper and claims that every great front man that has died of an young since the 1960s was actually murdered by none other than Eric fucking Clapton. Jimmy Hendrix, John Lennon, Jim Morrison, Freddy Mercury, Kurt Cobain, the list goes on. Clapton felt threatened by their talent so he snuffed them out.

14. North Korea is using Pokémon Go to spy on the U.S.

My brother-in-law had one a few years ago that Pokemon Go was really a tool N. Korea was using to spy on the US. I can’t remember all of the details, but kids were supposedly taking pictures of top-secret locations. Oh dear.

16. Mattress Firm is actually a money laundering sceme

That Mattress Firm stores are popping up everywhere cause they’re a part of a money laundering scheme. I mean… it’s pretty interesting to think about. We have at least 4 or 5 in my area alone, why do we need that many Mattress Firm stores when the average person only buys a bed every 7 to 10 years?

— obsessedcrf

24. Vaccines cause autism

That vaccines cause autism. It was bullshit made up by an ex porn star who wanted someone to blame for her kid’s disability. It is so ridiculously stupid, plus, autistic people are just fine. Sure, they may need some extra help, but in my experience they are happy, insightful and a good laugh. They can teach you a thing or two too when they get stuck into a topic.

— Yngvar_Stormblade

25. Dinosaurs never existed

That dinosaurs never existed and that the government went around burying fake bones to perpetuate the myth that they did.

I didn’t think people could be that stupid but I am proven wrong every damn day of my life.
