Okay, so it wasn't an outbreak, it was just one ninja, but school was canceled. Okay, wait, no it wasn't. I'm such a liar. It was only "locked down" for a short time, until it could be determined the ninja in the woods was not, in fact, a real ninja. This happened in New Jersey, where they have ninjas (ninji?) coming out their ears. When you look out your window in New Jersey, you might see a streak of black in the woods, but then again, you might not. But if you don't, it doesn't mean they're not there. Because, you know, they're ninjas. (See here.)
I just happened to recall that my younger cousin was a ninja once for Halloween many years ago, and my brother told him he looked like a black smurf.
P.S. Note: Should you take it into your soft heart to feed your elderly dog a diet of roast chicken, expect to become familiar with the smell of roast chicken farts. They smell exactly like roast chicken, but with a powerful, lingering component of. . . fart. It all makes perfect sense, really. Just, beware. And, why is it, I wonder, that dogs have a way of positioning themselves like they're aiming at you?
