One of the best and worst things about the internet is that if you think up an idea, there's a 99% chance someone else already thought of it. In this case I'm glad, because I'm lazy.
Anyway, here's the website for the conspiracy theory generator. Feel free to just post the title or summarize the whole thing or whatever; if you don't like your conspiracy theory, just refresh the page. I'll go first:
Here's the title: "The Truth About The Civil War and Tom Cruise"
Here's my favorite paragraph:
"I've decided not to have any children until the people involved admit their role. I don't want to bring any more innocent life into this sad, twisted world."
Edit: If you'd like to choose the topic of your conspiracy theory, use this link instead.
