We've all had "one of those days" at work where everything seems to go wrong. It's happened to me, it's happened to you, but maybe we've been lucky enough that our bad day wasn't captured on a high definition camera and recorded for posterity.
Remember a few months back when we were warned about packages containing "mystery seeds" showing up at U.S. homes? Given the choice, I think I might prefer to deal with a box of mystery seeds.
If you're a human being, there's every chance you've had an embarrassing moment. Maybe at school, or work, or someplace with a lot of people around.
If you've had it happen to you, perhaps watching it happen to this poor guy, during the changing of the guard in London, will give you that "misery loves company" feeling we all get from time to time...
