You know how you always wonder for that split second what it would be like to murder the paperboy when he rides by on his bike? What? His undeveloped, childish arm can never get the damn paper on your porch! Well, according to figures from the Left 4 Dead Blog, you've killed him. A whole bunch.

Or how about the in-laws? Oh man, you murdered them cold-blooded in Left 4 Dead 2. Basically, if every person on the planet was a zombie in the game, you've killed them -- 4.26 times. That would mean you've killed them, resurrected them, killed them again -- ah, you get it.

Another interesting figure: if the average height of a zombie is six feet tall, you stacked enough undead corpses end-to-end to circle the globe 1,322 times. You know how that's in italics? That's because it's crazy. In short: you are really good at killing zombies. Hey, don't feel bad for so much genocide! That's how it goes in the zombie apocalypse.
