If, for some strange reason, human being haven't wiped themselves off the face of the Earth before March 16th, 2880, we may all end up dead anyway. A great, big asteroid is headed straight for Earth.

That's right, there's a 1/300 chance that we should panic, run around gathering all our tinned food and shotguns, shoot a bunch of people (just incase they're the asteroid) and then go hide in an underground bunker in the middle of the desert. Of course, we'll need a lot of food; the asteroid won't be anywhere near here for another 878 years.
