How the world ends

When I heard of North and South Korea angrily poking at each other, I realized the world will end.

But how, exactly?


Step one:
A fat lady will sing in some public place.



Step two:
At this exact moment, North and South Korea (plus rest of world) will launch nuclear missiles at each other.



Step three:
The radiation will mutate pigs to have wings.



Step four:
ZOMBIES.



Step five:
2012 stuff.



Step six:
Earth goes boom.



The end.
