If you had read your ZSG, you'd know that the worst thing you can do in a zombie-overrun world is fire one of those things as all ghouls in 100-mile radius will converge on your location. STFU and wait.
To the poster who said black hole, DSC (I think it was them) did a special about the end of the world and a Black Hole is not a way we want to go out. Basically, the scientists stated that as the black hole moved closer to Earth it would suck off the ozone layer before it sucked all of off the planet. We'd die from the radiation, heat, etc. before the black hole ever got to us.
Actually, because of time dilation, it would take forever. I voted zombies (although it should be ghouls), because it is one of the few scenarios that can actually be survived.

Definitely asteroid b/c I would rule the post-apocalyptic survivors with my rugged good looks and off the chart charisma.
In my Zombie Apocalypse, there be a hot chick with a dirtied tank top, a high powered revolver, and a shot gun that has just the right kick and ammo to last you for the night.
shotguns need a large shot (like 00 or 000 buck or a slug) to get reliable skull penetration. You would be better off with a rifle and a handgun.
that guy is an idiot, he wrote it for comedy. in a zombie world loud noises are common place. Zombies work on smell not hearing anyways.
