I've had my fair share of fun with conspiracy theories, heck I've even come up with some myself. I remember telling my classmates that our math teacher was part of the illuminati trying to force us to join him with numbers. I admit it wasn't my best made up story but it sure did work for them.
I told my sister the tooth fairy was real and wasn't going to give her anything if she didn't give me a portion of her meat every night for 3 weeks, best 3 weeks of my life. Let's face it, conspiracy theories are fun.
Conspiracy theories are like 
Another one is the earth being flat even with all the very educative children's cartoons we've seen. This is a theory I want to believe because I have a couple of people I want to push over the edge if I ever see it.
Now if the illuminati is truly real, they've left me disappointed with their not so secret society. I mean the whole point was to control the masses from the shadows. Whats the point of being secretive if you can't stay secret.
The bigfoot own gets me every time. Bigfoot is supposed to be the missing link between humans and apes meaning more intelligent than apes but less intelligent than human being yet this creature has managed to elude us every single time. I think we need to check ourselves as the most "intelligent" creatures on the planet.
They say if you hold up a candle in a dark room room by yourself and repeat bloody Mary three times in front of a mirror, she appears. Well thats more of an urban legend than a conspiracy theory. Usually I like to debunk these things myself so I can tell people that believe it what sort of assholes they are but I can't this time. Its not because I'm scared or anything, I just don't have a candle but tell me how it goes when you try.
The last one I can think of is the moon being fake, it was made by China. I believe I can easily debunk this one. If the moon was really made by China, it wouldn't have lasted this long.
