Have you ever been reading the news and really thought by the half way mark it would stop and say "just kidding! That really didn't happen. We just made that up to screw with your head. Can you imagine if that was real? That would be totally messed up! Now for the real news..."
I read the news every day and at least once I hve to check the source to make sure it isn't from The Onion. It usually has to do with politics. It's easier to believe an earthquake/tsunami/volcano/cyclone news story than the stupidity of a single person.
