I added The Onion to my RSS feed a bit over a week ago. Since then there have been a couple headlines where I had to check just to make sure they were fakes, but I haven’t actually been caught believing one yet.
Instead, I was caught out by a real headline that I was sure would be a fake: Fugitive wanted for attempted murder found at White House, where he worked for National Security Council. That’s actually a real Boingboing headline — although the underlying story is slightly less sensational than you might think: instead of being in the Cabinet, the fugitive was only a contract worker, and the Secret Service is trying to make it sound like they caught him on his first day of work, although the linked story doesn’t quite say that.
